Objectives: To determine the prevalence of retinal lesions and describe the fundoscopic findings of retinopathy in Greyhound dogs in the Manawatu/Whanganui region of New Zealand. To examine possible associations between sex, age, and racing variables with retinopathy in the study population. To describe retinal histologic findings in seven Greyhounds with retinopathy in New Zealand. Methods: Two hundred Greyhound dogs from the Manawatu/Whanganui region of New Zealand underwent fundoscopy and fundic photography to identify and score the degree of retinopathy. Associations between retinopathy and age, sex, as well as racing variables, were examined. Histologic examination of the retina was undertaken on the eyes of seven Greyhounds from the Manawatu and Canterbury regions previously diagnosed with retinopathy by fundoscopy. Results: Fifty dogs (25.1%) were identified with retinopathy of varying degrees of severity. In at least one eye, 7.5% of dogs had mild retinopathy, 11.6% moderate retinopathy, and 6.0% severe retinopathy. Males were more likely to be affected in both eyes and with moderate or severe grades, than females. Increasing age was not associated with increased prevalence of retinopathy, nor increased grade of severity. Retinal histology identified multifocal retinal detachment in 5 of the 7 cases examined and other common lesions included choroidal necrosis and outer to full‐thickness retinal atrophy in the absence of significant inflammation. Conclusions: Retinopathy is prevalent in Greyhounds in the Manawatu/Whanganui region of New Zealand, but more research is required to elucidate the etiopathogenesis. Consideration should be made to include mandatory eye health examination in racing Greyhound dogs. [ABSTRACT FROM AUTHOR]

To describe the characteristics of companion animal rescue organisations (CARO) in New Zealand; to describe current capacity, resource limitations and challenges of CARO with a particular focus on cats and dogs; and to explore support for creating a national database of CARO in New Zealand. A cross-sectional survey was administered to CARO in New Zealand in May 2022. The survey asked about organisational characteristics, types and numbers of animals cared for, services provided, policies, staffing, funding sources, challenges, and attitudes towards a national database for rescue organisations. Descriptive statistics were provided for all quantitative study variables and free-text comments were analysed for common themes. The survey was completed by 106/208 (51%) known CARO distributed across the country. These CARO provided services to an estimated 59,874 homeless animals annually with 86/106 (81%) providing services to cats and/or dogs. Primary services provided by CARO who cared for cats or dogs included rehoming (72/86; 84%) and housing (70/86; 81%) animals. Intake was managed through a combination of strategies. Donations (72/86; 82%) were the main funding source. The 62 registered charities were more likely to report being funded by grants than the 23 non-charities (39/62 (63%) vs. 1/23 (4%); p < 0.001), and non-charities were more likely to self-fund (18/23 (78%) vs. 20/62 (32%); p < 0.001). Nearly half of the CARO that provided workforce information (35/72; 49%) had a workforce of 10 or fewer including volunteers. A total of 5,699 people worked for 86 CARO that care for cats or dogs of whom 4,847 (85%) were part-time volunteers. Of the 72 cat and dog CARO who provided workforce information, 57/72 (79%) relied solely on volunteers. The majority of all 106 CARO respondents (78/106; 73%) indicated they were likely to register on a national database of CARO, subject to addressing concerns about time required and information security. CARO respondents described challenges of insufficient funding, access to veterinary services, and a shortage of volunteers and foster homes, with additional concerns including a lack of public awareness, supportive legislation, and resources. Financial support (90/106; 85%) and policy change (76/106; 72%) were preferred support options. This study highlights the significant role played by CARO in New Zealand and the challenges they face, emphasising the need for financial support, legislation, and initiatives extending beyond the rescue sector to reduce the number of animals being surrendered. The findings also suggest a willingness among CARO to participate in a national database. [ABSTRACT FROM AUTHOR]

Medical records of four dogs diagnosed with protothecosis in New Zealand were reviewed. The dogs were aged between 4 and 9 years and three of the four dogs were female. Breeds were one Labrador, one Miniature Schnauzer and two crossbreeds. The reasons for initial veterinary evaluation were a cough and opaque appearance of the right eye (Case 1), diarrhoea (Cases 2 and 3), and cutaneous disease (Case 4). The ocular signs were characterised by panuveitis, retinal detachment and secondary glaucoma. Gastrointestinal signs included chronic haemorrhagic diarrhoea due to colitis. Three cases had disseminated infection and developed both bilateral, blinding, ocular disease and chronic gastrointestinal disease. Cutaneous signs consisted of draining fistulae over the olecranon, multifocal cutaneous nodules, and ulceration and tracts of the foot pads. Disseminated protothecosis was confirmed by histopathology of biopsied ocular tissues in Cases 1 and 2 and by gastrointestinal biopsies in Case 3. Prototheca spp. were also identified in cytological specimens from Cases 1 and 4 and recovered by culture in Cases 2 and 4. Cutaneous protothecosis was diagnosed in Case 4 initially by cytology and histopathology of skin lesions, and Prototheca zopfii was confirmed by PCR of cultured organisms. Prior to diagnosis of protothecosis, a variety of treatments were prescribed to treat the gastrointestinal and ocular signs. After diagnosis, only Cases 2 and 4 received medication aimed at treating the protothecal infection, which was itraconazole in both cases. Following the progression of clinical signs and concerns about quality of life, all four dogs were euthanised. Disseminated protothecosis in three dogs, cutaneous protothecosis in one dog. Canine protothecosis is rarely reported, despite the ubiquity of the causal algae, and the disease usually carries an extremely grave prognosis when infection is generalised. In New Zealand, protothecosis should be considered as a differential diagnosis in dogs with panuveitis, chorioretinitis or retinal detachment, colitis, or nodular, ulcerative or fistulating cutaneous lesions.

Hookworms (Ancylostomatidae) are well‐known parasites in dogs due to their health impacts and zoonotic potential. While faecal analysis is the traditional method for detection, improvements in husbandry and deworming have decreased their prevalence in urban owned dogs. Drug resistance in Ancylostoma caninum is becoming a discussion point in small animal practices across the region. This study aimed to identify hookworm species present in Australian and New Zealand dogs using molecular techniques. The ITS‐2 and isotype‐1 β‐tubulin assays were used to identify and quantify hookworm species. Results showed absence of coinfection in Australian samples from Greater Sydney region belonging either to A. caninum or Uncinaria stenocephala, while New Zealand samples were a mixture of A. caninum and U. stenocephala. The amplified isotype‐1 β‐tubulin sequences exhibited susceptibility to benzimidazole drugs. Rare mutations were identified in A. caninum and U. stenocephala sequences, representing a small percentage of reads. This study highlights the importance of molecular techniques in accurately identifying and quantifying hookworm species in dog populations. [ABSTRACT FROM AUTHOR]

To collect data on protocols used by New Zealand veterinarians to perform euthanasia of dogs and cats, and to explore opinions towards the training they received in euthanasia during veterinary school. A cross-sectional survey was administered to all veterinarians registered with the Veterinary Council of New Zealand. The survey asked respondents about their practices' policies for euthanasia; protocols for performing euthanasia of dogs and cats; opinions towards euthanasia training received in veterinary school; and subsequent experiences with euthanasia in practice. Descriptive statistics were provided for all quantitative study variables and thematic analysis was performed on the free-text comments. The survey was completed by 361/1,448 (24.9%) veterinarians in companion or mixed animal practice. The mean numbers of dogs and cats euthanised each month were 7.2 (median 5; min 0; max 60) and 7.9 (median 5; min 0; max 60), respectively. Fewer than half of respondents reported that their clinic had a standard protocol for euthanising dogs (147/361; 40.7%) or cats (157/361; 43.5%). For euthanasia of dogs, 119/361 (32.9%) always used sedation while 71/361 (19.7%) indicated that they would not use sedation. For euthanasia of cats, 170/361 (47.1%) always used sedation while 53/361 (14.7%) indicated that they would not use sedation. Placement of IV catheters, methods for patient restraint, preferences towards the presence of owners during euthanasia, services provided with euthanasia, and discussions with owners were also highly variable and handled case-by-case depending on the client, patient, and clinical scenario. When asked about the euthanasia training received at veterinary school, it was generally ranked as below satisfactory, with approximately one-third of respondents indicating that they received no training in dealing with emotional clients (113/361; 31.3%), sedation protocols for euthanasia (107/361; 29.6%), or managing compassion fatigue (132/361; 36.6%). Most respondents (268/361; 74.2%) received no formal training in euthanasia after graduation and learned from experience or discussions with colleagues. Providing animals and owners with a good experience during the euthanasia process was highlighted as important for managing compassion fatigue. Euthanasia is a common procedure in companion animal practice and there is considerable variation in how veterinarians approach both the technical and non-technical elements. Training provided during veterinary school was generally considered below satisfactory, particularly regarding managing compassion fatigue and clients' emotional needs. Providing veterinarians with additional training on adapting their euthanasia protocols to different clinical scenarios may improve the experience for patients, owners and veterinary staff.

Purpose: This study determined the diversity and distribution of tick species infesting domestic dogs and the life cycle parameters of the dominant dog tick species. Methods: An island-wide, cross-sectional survey of tick species infesting domestic dogs was carried out, and the life cycle of the most commonly occurring dog tick, Rhipicephalus sanguineus was studied under laboratory conditions. Results: A total of 3026 ticks were collected from 1219 dogs in all 25 districts. Eight species in five genera were identified: R. sanguineus (63.4%), R. haemaphysaloides (22.0%), Haemaphysalis bispinosa (12.5%), Haemaphysalis intermedia (0.9%), Haemaphysalis turturis (0.6%), Amblyomma integrum (0.4%), Dermacentor auratus (0.2%) and Hyalomma sp (0.1%). R. sanguineus was the dominant species in the Dry and Wet zones, while R. haemaphysaloides was the dominant species in the Intermediate Zone. Species diversity (Shannon diversity index H) was 1.135, 1.021and 0.849 in the Intermediate, Dry and Wet zones, respectively. The three-host life cycle of R. sanguineus was completed within 70–126 days, and all three stages successfully fed on New Zealand white rabbits under laboratory conditions. The Reproductive Efficiency Index (REI) and Reproductive Fitness Index (RFI) were 50.8 ± 9.69 and 9.1 ± 5.01, respectively. Larger females had higher reproductive success. Conclusions: Of the eight species infesting domestic dogs in Sri Lanka, R. sanguineaus was the most frequently occurring tick species. The three-host life cycle of R. sanguineus was successfully completed within an average of 98 days on New Zealand white rabbits. The number of eggs laid, duration of the pre-oviposition period, incubation period and parasitic periods of all three life stages were lower than in previous records. [ABSTRACT FROM AUTHOR]

Aims: To determine whether evidence for infection with Theileria orientalis (Ikeda) could be identified in samples of commercial red deer (Cervus elaphus) , horses, and working farm dogs in New Zealand., Methods: Blood samples were collected during October and November 2019 from a convenience sample of red deer (n = 57) at slaughter. Equine blood samples (n = 50) were convenience-sampled from those submitted to a veterinary pathology laboratory for routine testing in January 2020. Blood samples, collected for a previous study from a convenience sample of Huntaway dogs (n = 115) from rural regions throughout the North and South Islands of New Zealand between August 2018 and December 2020, were also tested. DNA was extracted and quantitative PCR was used to detect the T. orientalis Ikeda major piroplasm surface protein (MPSP) gene. A standard curve of five serial 10-fold dilutions of a plasmid carrying a fragment of the T. orientalis MPSP gene was used to quantify the number of T. orientalis organisms in the samples. MPSP amplicons obtained by end-point PCR on positive samples were isolated and subjected to DNA sequencing. The resulting sequences were compared to previously published T. orientalis sequences., Results: There were 6/57 (10%) samples positive for T. orientalis Ikeda from the deer and no samples positive for T. orientalis Ikeda from the working dogs or horses. The mean infection intensity for the six PCR-positive deer was 5.1 (min 2.2, max 12.4) T. orientalis Ikeda organisms/µL., Conclusions and Clinical Relevance: Red deer can potentially sustain low infection intensities of T. orientalis Ikeda and could act as reservoirs of infected ticks. Further studies are needed to determine whether naïve ticks feeding on infected red deer can themselves become infected.

Two dogs were referred to Veterinary Specialists Aotearoa for evaluation and treatment after sustaining significant head trauma. Case 1 was a 7-month-old, female Staffordshire Bull Terrier who was hit by a car at low speed. Case 2 was a 2-year old, male neutered German Shepherd who sustained a gunshot wound to the head whilst on duty for the New Zealand Police Dog Unit. The dog in Case 1 suffered numerous facial fractures which caused collapse of the ventral nasal meatus and dorsal nasopharyngeal wall. The dog in Case 2 had extensive osseous and soft tissue damage to the nose, nasopharynx and cervical region with severe narrowing of the ventral meatuses, nasopharyngeal meatus and rostral nasopharynx due to multiple fracture fragments and shrapnel pieces. A diagnosis of traumatic nasopharyngeal stenosis was made in each case by computed tomography. Mechanical balloon dilation was used to treat the stenosis in both dogs. The balloon dilations were performed using a 12-mm balloon dilation catheter inserted in an antegrade fashion. In the first dog, the procedure was performed blind and was repeated three times with 5- and 9-day intervals between dilations. In the second dog, the procedure was performed under endoscopic guidance and again, was repeated three times with a 7-day interval between dilations. Clinical success was reported in both patients following treatment and the second dog also underwent a follow-up computed tomography scan which confirmed resolution of the stenosis. Traumatic nasopharyngeal stenosis that was successfully treated with balloon dilation. Findings suggest that balloon dilation may be an effective technique for the treatment of traumatic nasopharyngeal stenosis in dogs. Multiple dilation procedures are likely required, but the procedure can ultimately result in long term clinical resolution.

A 1-year-old Border Terrier presented with acute onset of neurological signs and neck pain. Severe generalised ataxia, muscle tremors and cranial nerve deficits were noted. Multifocal brain lesions were suspected based on neurological examination. Computed tomography revealed an abdominal mass and cerebellar herniation through the foramen magnum. Cytological and histopathological analysis of the abdominal mass revealed necrotising and granulomatous lymphadenitis with intralesional algal elements most consistent with Prototheca spp.. Culture of a sample from the mesenteric lymph node confirmed the presence of Prototheca spp. which was identified as P. bovis based on sequencing of a DNA fragment amplified by PCR. Following inadequate response to symptomatic therapy and poor prognosis, the dog was subjected to euthanasia. Histopathological evaluation of the central nervous system lesions, identified granulomatous meningitis and ventriculitis with the presence of intralesional algae. Disseminated protothecosis with granulomatous meningitis and ventriculitis caused by Prototheca bovis (formerly P. zopfii gen. 2). This is the first case report of disseminated protothecosis with central nervous system involvement in a dog in New Zealand. [ABSTRACT FROM AUTHOR]

To evaluate the proportions of canine mammary gland lesions submitted to a New Zealand diagnostic laboratory, that were neoplastic vs. non-neoplastic and, among neoplasms, malignant vs. benign, and to determine whether age, reproductive status or breed of dog, or size of the mammary mass were associated with the histological diagnosis. Canine mammary gland biopsies submitted between the start of 2012 and the end of 2016 were selected from the surgical biopsy database of IDEXX Laboratories, NZ. For each case, details on age, breed, and reproductive status of the patient were registered as reported by the submitting veterinarians, along with the size (classified as small, medium or large) of the lesion and the histological diagnosis reported by the pathologists. χ2 tests and independent sample t-tests were performed to evaluate associations. Samples (n = 895) were submitted from 797 dogs, of which 673 had mammary neoplasms while 124 had non-neoplastic lesions. Neoplasms composed of a single nodule were found in 591/673 (87.8%) dogs, while 82/673 (12.2%) dogs had multiple nodules. Of the total 771 neoplasms, 432 (56.0%) were histologically malignant, while 339 (44.0%) were benign. Among malignancies, the most common histological sub-types were simple carcinoma (160/771; 20.8%), complex carcinoma (54/771; 7%), and ductal carcinoma (32/771; 4.2%), while benign mixed mammary tumour (128/771, 16.6%) and complex adenoma (105/771; 13.6%) were the most frequently reported benign mammary neoplasms. There was no evidence of a difference in age (p = 0.09) or reproductive status (p = 0.79) of the dog or the size of the mass (p = 0.21) between neoplastic and non-neoplastic lesions. However, neoplastic mammary gland lesions were more frequent in purebred dogs (612/671; 91.2%) than crossbred dogs (61/126; 48.4%; p < 0.001). There was no evidence of a difference in age (p = 0.15) reproductive status (p = 0.36) or breed (p = 0.45) of dog between malignant and benign neoplasms. There was an association between size and histological benign or malignant status of a neoplasm (φ = 0.65, p < 0.001). Most canine mammary gland samples submitted for examination were neoplastic with slightly more malignant than benign lesions. Masses submitted from purebred dogs were more likely to be neoplastic, while large neoplasms were more likely to be malignant. The present findings provide the first description of the distribution of mammary gland lesions in a relatively large number of dogs in New Zealand, representing a preliminary investigation of canine mammary gland diseases in this country.

Aims: To obtain preliminary data on changes in gait from the use of a green-lipped mussel ( Perna canaliculus ) extract product in working farm dogs with musculoskeletal abnormalities using accelerometry. Methods: New Zealand working farm dogs (n = 32) with signs of musculoskeletal abnormalities were enrolled in a double-blinded, placebo-controlled cross-over study. Each dog was allocated to one of six groups to receive three trial substances (180 mg full fat green-lipped mussel extract (GLME 180 ); 220 mg full fat green-lipped mussel extract (GLME 220 ); placebo) in one of the six possible different orders. Each trial substance was administered orally once a day for an 8-week period, with a 4-week washout in between each. Dogs wore a collar-mounted triaxial accelerometer for the study duration. Diet and activity were not controlled. Accelerations were recorded continuously and analysed (n = 27) in 10-second activity epochs partitioned into daytime and night-time periods. Analysis of activity during the daytime period was limited to epochs when dogs were gaiting faster than a walk. The median and IQR of activity were determined for the daytime and night-time. Additionally, the 75th and 90th percentiles of daytime activity for each 24-hour period were determined. Mixed effects linear regression models were constructed to determine if each trial substance altered the response variables., Results: During the daytime, the 90th percentile was higher when dogs were given GLME 220 compared with the placebo (β coefficient 2.6; 95% CI = 0.25-4.94; p = 0.03). Dogs that started the trial with the GLME products had a higher 90th percentile activity compared with dogs that began with the placebo (β coefficient 26.26; 95% CI = 0.45-52.06; p = 0.046). The 75th percentile for activity was not affected by the GLME product. The daytime IQR was larger when dogs were given the GLME 180 product compared with the placebo (β coefficient 1.25; 95% CI = 0.12-2.37; p = 0.03). Night-time median activity and the IQR was greater in dogs that started the trial with the GLME products than in dogs that began with the placebo. The night-time IQR for activity was greater for GLME 180 than for the placebo., Conclusions: Administration of a low dose of the GLME-containing product increased peak activity in working farm dogs with signs of musculoskeletal abnormalities and may improve their performance., Clinical Relevance: Even mildly affected working farm dogs might benefit from support of their musculoskeletal abnormalities, and this particular GLME-based product shows promise as an adjunct to other management strategies.

In New Zealand, dogs appear in the earliest archaeological contexts and were a common sight in the Māori villages described by European explorers in the late eighteenth century. In this review, we argue that the fundamental nature of dog–human relationships remained stable throughout New Zealand's early history, despite major environmental change and transformations in Māori settlement patterns, subsistence systems, and social organisation. Although there are variations in dog abundance levels in the archaeological record through time, these are likely due to differences in site function rather than dogs' diminishing importance or changing status. Dogs are unique in early New Zealand as the only animal that shared living space with humans. They did so as free-ranging populations; travelling with people, interacting in village life, and playing diverse roles in Māori social, technological, and ritual systems. [ABSTRACT FROM AUTHOR]

As the introduction of concentrated cattle pour‐on products containing abamectin, there have been veterinary reports of both fatal and non‐fatal poisoning in New Zealand working dogs. Because these products are highly palatable to dogs, a toxic dose is readily ingested. The pharmacokinetic properties of abamectin in dogs are not published in the public domain. This information is important in understanding the processes of absorption and elimination when treating poisoned dogs and is useful in determining an appropriate treatment for poisoned dogs. The pharmacokinetic properties of abamectin administered orally to six healthy dogs (3 male and 3 female) at a dose of 0.2 mg/kg were established. Plasma concentrations of abamectin were determined by high‐performance liquid chromatography (HPLC) coupled with a fluorescence detector. The maximum plasma concentration (Cmax) for abamectin was 135.52 ± 38.6 ng/ml at 3.16 ± 0.75 h. The elimination half‐life (T1/2 elim (h)) was 26.51 ± 6.86 h. The area under the curve (AUC 0‐∞) was 3723.50 ± 1213.08 ng h/ml. The mean residence time (MRT) was 38.82 ± 8.93 h. These pharmacokinetic data provide helpful information regarding the treatment of poisoned dogs. [ABSTRACT FROM AUTHOR]

Canine acute hemorrhagic diarrhea syndrome (AHDS) has been associated in some studies with Clostridioides perfringens overgrowth and toxin-mediated necrosis of the intestinal mucosa. We aimed to determine the effect of a single fecal microbiota transplantation (FMT) on clinical scores and fecal microbiomes of 1 and 7 dogs with AHDS from New Zealand and South Africa. We hypothesized that FMT would improve AHDS clinical scores and increase microbiota alpha-diversity and short-chain fatty acid (SCFA)-producing microbial communities' abundances in dogs with AHDS after FMT. We sequenced the V3-V4 region of the 16S-rRNA gene in the feces of AHDS FMT-recipients and sham-treated control dogs, and their healthy donors at admission, discharge, and 30 days post-discharge. There were no significant differences in median AHDS clinical scores between FMT-recipients and sham-treated controls at admission or discharge (P = 0.22, P = 0.41). At admission, the Shannon diversity index (SDI) was lower in AHDS dogs than healthy donors (P = 0.002). The SDI did not change from admission to 30 days in sham-treated dogs yet increased in FMT-recipients from admission to discharge (P = 0.04) to levels not different than donors (P = 0.33) but significantly higher than sham-treated controls (P = 0.002). At 30 days, the SDI did not differ between FMT recipients, sham-treated controls, and donors (P = 0.88). Principal coordinate analysis of the Bray-Curtis index separated post-FMT and donor dogs from pre-FMT and sham-treated dogs (P = 0.009) because of increased SCFA-producing genera's abundances after FMT. A single co-abundance subnetwork contained many of the same OTUs found to be differentially abundant in FMT-recipients, and the abundance of this module was increased in FMT-recipients at discharge and 30 days, compared to sham-treated controls. We conclude in this small pilot study FMT did not have any clinical benefit. A single FMT procedure has the potential to increase bacterial communities of SCFA-producing genera important for intestinal health up to 30 days post-FMT. [ABSTRACT FROM AUTHOR]

Aims: To isolate canine respiratory coronavirus (CRCoV) and canine pneumovirus (CnPnV) in cell culture and to compare partial genomic sequences of CRCoV and CnPnV from New Zealand with those from other countries., Methods: Oropharyngeal swab samples from dogs affected by canine infectious respiratory disease syndrome that were positive for CnPnV (n = 15) or CRCoV (n = 1) by virus-specific reverse transcriptase quantitative PCR (RT-qPCR) in a previous study comprised the starting material. Virus isolation was performed in HRT-18 cells for CRCoV and RAW 264.7 and Vero cells for CnPnV. The entire sequence of CnPnV G protein (1,266 nucleotides) and most (8,063/9,707 nucleotides) of the 3' region of CRCoV that codes for 10 structural and accessory proteins were amplified and sequenced. The sequences were analysed and compared with other sequences available in GenBank using standard molecular tools including phylogenetic analysis., Results: Virus isolation was unsuccessful for both CRCoV and CnPnV. Pneumovirus G protein was amplified from 3/15 (20%) samples that were positive for CnPnV RNA by RT-qPCR. Two of these (NZ-048 and NZ-049) were 100% identical to each other, and 90.9% identical to the third one (NZ-007). Based on phylogenetic analysis of the G protein gene, CnPnV NZ-048 and NZ-049 clustered with sequences from the USA, Thailand and Italy in group A, and CnPnV NZ-007 clustered with sequences from the USA in group B. The characteristics of the predicted genes (length, position) and their putative protein products (size, predicted structure, presence of N- and O-glycosylation sites) of the New Zealand CRCoV sequence were consistent with those reported previously, except for the region located between open reading frame (ORF)3 (coding for S protein) and ORF6 (coding for E protein). The New Zealand virus was predicted to encode 5.9 kDa, 27 kDa and 12.7 kDa proteins, which differed from the putative coding capacity of this region reported for CRCoV from other countries., Conclusions: This report represents the first characterisation of partial genomic sequences of CRCoV and CnPnV from New Zealand. Our results suggest that the population of CnPnV circulating in New Zealand is not homogeneous, and that the viruses from two clades described overseas are also present here. Limited conclusions can be made based on only one CRCoV sequence, but the putative differences in the coding capacity of New Zealand CRCoV support the previously reported variability of this region. The reasons for such variability and its biological implications need to be further elucidated.

Aims: To describe the variation in surgical techniques used by veterinarians to perform routine dog and cat spays in first-opinion veterinary practice in New Zealand, and how these techniques differed with the number of years since the veterinarian graduated. Methods: A cross-sectional survey of veterinarians registered to practice in New Zealand was conducted online between 1 April and 30 May 2018. Respondents were asked their year of graduation and about the procedures, they would use to perform a routine spay of a healthy, 5 kg, young adult, female domestic shorthair cat, and a healthy, 20 kg, young adult, female mixed-breed dog. The number of years since graduation was calculated by subtracting the reported year of graduation from 2018. Results: Overall, 282 respondents provided details about dog spays, and 361 about cat spays, and the median number of years since graduation was 14 (min 0, max 50). Only 54/282 (19.1%) respondents performing dog spays and 43/361 (11.9%) performing cat spays wore a surgical cap, gown, mask, and gloves. For dog spays, 278 (98.6%) respondents used a ventral midline approach and 147 (52.1%) used manual exteriorisation of the uterus. Most used two clamps (168; 59.6%) and used two encircling ligatures (152; 53.9%) for removal of the uterus. For cat spays, 254 (70.4%) respondents used a ventral midline approach and 313 (86.7%) used a spay hook for exteriorising the uterus. Most used two clamps (250; 69.3%) with one encircling ligature (213; 59.0%) for removal of the uterus. Simple interrupted external or intradermal patterns were mostly used for skin closure for both dog and cat spays. For cat spays, the percentage of respondents using the ventral midline approach decreased with increasing years since graduation (p < 0.001). For both dog and cat spays, the percentage of respondents using two encircling ligatures and transfixation ligation of the uterus, and using a simple continuous suture pattern for the closure of the abdomen, decreased with number of years since graduation (p < 0.05). Conclusions and clinical relevance: Veterinarians responding to this survey used a wide range of techniques to perform routine dog and cat spays, some of which were associated with the number of years since graduation. It may be beneficial to provide veterinarians with resources to reflect on their current approaches for performing routine spays. However further research is needed to determine whether any surgical techniques are superior to others. [ABSTRACT FROM AUTHOR]

Cystic echinococcosis (CE), caused by Echinococcus granulosus, is a chronic and debilitating zoonotic larval cestode infection in humans, which is principally transmitted between dogs and domestic livestock, particularly sheep. Human CE occurs in almost all pastoral communities and rangeland areas of the underdeveloped and developed world. Control programmes against CE have been implemented in several endemic countries to reduce or eliminate the disease. New Zealand and Tasmania are examples of some of the first programmes to be undertaken (in insular territories) and which were very successful in the elimination of CE. The advent and proven effectiveness of praziquantel, plus the experience of insular models, produced high expectations for rapid advances in a second generation of control programmes undertaken in continental areas (Argentina, Uruguay and Chile). Nevertheless, only moderate gains in CE control have been made and the impact on prevalence among humans has been slight. A major impediment to the adoption of procedures that were successful in New Zealand and Tasmania has been the requirement to administer praziquantel to dogs in rural areas eight times per year over numerous years. In addition, there have been clear technological improvements made in the diagnosis of canine echinococcosis for surveillance, the genetic characterization of parasite strains and in vaccination against CE infection in livestock. In order to establish new paradigms and appropriate combinations of control strategies, we have carried out a review and discussion of the available control tools and control models. Control strategies must be suitable and sustainable to benefit the Echinococcosis–endemic areas primarily, which at the same time are the poorest regions of the world. [ABSTRACT FROM AUTHOR]

Across the globe there is an increasing number of initiatives promoting biodiversity in urban areas – both for the benefit of native wildlife and the people who live in cities. In these situations, the role that companion animals, such as cats and dogs, play as predators of wildlife becomes increasingly important. The objectives of this case study were two-fold. Firstly, to investigate activity patterns of domestic cats inside a 75 ha urban reserve; and secondly, to survey the attitudes and beliefs of the community neighbouring the reserve about pet ownership and the threat that domestic cats and dogs may pose to native wildlife. Twelve motion-activated camera traps were triggered by cats 83 times during the 32-day study period. Distance from reserve edge was found to affect the rate of cat detection, with almost six times as many cat-related triggers 25 m from the reserve edge than at 100 m. Distance from the nearest walking track within the reserve had no significant effect on detection rate. The online survey found that the urban reserve is highly valued by the local community for its provision of habitat for native wildlife and, in general, there is strong agreement that the threat cats pose to native wildlife is a problem. Attitudes of cat owners, however, did differ from those of non-owners, especially in their degree of support for suggested solutions. Advocacy and education about the effects of cats on native wildlife may alter the behaviour of cat owners who value native biodiversity, however, these strategies alone are unlikely to persuade pet owners who are not motivated by conservation goals.

Aims: To describe the opinions of respondents to an online survey on desexing, microchipping and pet registration, and the management of cats, and aggressive dogs in New Zealand. Methods: A cross-sectional survey was conducted online from 18–22 June 2015 using a permission-based panel of New Zealand residents aged ≥18 years. Questions included demographics of respondents, number of dogs and cats owned, and opinions on desexing, microchipping, pet registration, management of cats and aggressive dogs. Results: Of the 1,572 survey respondents, 216 (13.7%) owned ≥1 dog and ≥1 cat, 227 (14.4%) owned ≥1 dog and no cats, 480 (30.5%) owned ≥1 cat and no dogs, and 559 (35.6%) did not own any pets. The majority of dogs (456/613; 74.8%) and cats (974/1,045; 93.2%) were desexed. The most common reasons for not desexing pets were cost, feeling that it was not needed, or keeping the dog for breeding. Of the 613 dogs, 557 (90.9%) were registered with the local council, and 434 (71.0%) were microchipped, but only 290 (47.3%) were registered in the national database. Of the 1,045 cats, 326 (31.2%) were microchipped and 279/486 (57.4%) owners felt that it was unnecessary. Of the 1,572 respondents, 947 (60.2%) were unaware of stray cats in their local community, and 479 (30.5%) stated that local councils, or animal welfare organisations (546/1,572; 34.7%) should be responsible for managing strays. Among all 1,572 respondents, 787 (50.1%) thought stray cats should be assessed and subjected to euthanasia. Compared with non-pet owners, a lower percentage of cat owners agreed that cats should be confined (p < 0.001). When asked to choose the most appropriate course of action for dogs that had bitten people or other animals, 849 (54.0%) and 820 (52.5%) respondents, respectively, agreed that the dog should be assessed by an expert who would then determine the appropriate action. Compared with non-pet owners, a lower percentage of dog owners supported registration and education of dog owners, aggressive dogs being destroyed, and giving more power to local councils (p < 0.05). Conclusions: The results highlight opportunities to improve owner compliance with desexing, microchipping and registration of dogs and cats. Opinions towards management of stray cat and aggressive dogs varied between pet owners and non-owners. Further research is needed to better understand how to engage the public in important dog and cat management policy issues. [ABSTRACT FROM AUTHOR]

Aims: To describe the demographics of and predictors for pet ownership, reasons for visiting a veterinarian, and pet-related expenditure in pet owners in New Zealand. Methods: A cross-sectional online survey was conducted from 18–22 June 2015 using a permission-based panel of New Zealand residents aged ≥18 years. Questions included demographics of respondents, number of pets and reasons for owning or not owning pets, number of visits and reasons for visiting a veterinarian, and pet-related expenditure. Results: Of the 1,572 respondents who completed the survey, 1,013 (64.4%) owned ≥1 pet. Of these, 443 owned dogs, 696 cats, 32 horses, 103 birds, 55 rabbits, and 159 owned fish. Companionship was the most common reason for getting dogs, cats, and birds; horses were mostly owned as a hobby, rabbits to provide fun for children, and fish as a source of relaxation. The majority of dog, cat, and rabbit owners considered their pets to be family members; horse owners almost equally considered their horses a hobby or a family member. The odds of pet ownership increased for respondents from a rural region, having a higher household income, having children and being female. Overall, 711/1,013 (70.2%) pet-owning respondents had taken ≥1 animal to the veterinarian in the previous year, with the most common reasons being for vaccination or annual check-ups or health issues. Respondents who considered their pets trusted companions, had a higher income, and owned dogs or cats compared with other species, were most likely to have taken their pet to a veterinarian. The greatest pet-related expenditure for all species was food. The median yearly veterinary expenditure was $200–499 by dog owners, $100–199 by cat owners, and <$100 by horse, bird, rabbit, and fish owners. The best source of information for pet-related issues was considered to be veterinarians by 724/1,001 (72.3%) owners, and the internet by 509/1,001 (50.8%) owners. Conclusions: Among survey respondents, pet ownership was common and pets filled a variety of roles in the household. Pet owners reported spending considerable amounts of money on their pets each year, but some of them may be underutilising veterinary services despite veterinarians being considered as valuable sources of information about pet-related issues.

'Go Slow myopathy' (GSM) is a suspected toxic myopathy in dogs that primarily occurs in the North Island of New Zealand, and affected dogs usually have a history of consuming meat, offal or bones from wild pigs (including previously frozen and/or cooked meat). Previous epidemiological and pathological studies on GSM have demonstrated that changes in mitochondrial structure and function are most likely caused by an environmental toxin that dogs are exposed to through the ingestion of wild pig. The disease has clinical, histological and biochemical similarities to poisoning in people and animals from the plant Ageratina altissima (white snakeroot). Aqueous and lipid extracts were prepared from liver samples of 24 clinically normal dogs and 15 dogs with GSM for untargeted liquid chromatography-mass spectrometry. Group-wise comparisons of mass spectral data revealed 38 features that were significantly different (FDR<0.05) between normal dogs and those with GSM in aqueous extracts, and 316 significantly different features in lipid extracts. No definitive cause of the myopathy was identified, but alkaloids derived from several plant species were among the possible identities of features that were more abundant in liver samples from affected dogs compared to normal dogs. Mass spectral data also revealed that dogs with GSM have reduced hepatic phospholipid and sphingolipid concentrations relative to normal dogs. In addition, affected dogs had changes in the abundance of kynurenic acid, various dicarboxylic acids and N-acetylated branch chain amino acids, suggestive of mitochondrial dysfunction. • 'Go Slow' myopathy (GSM) of dogs in New Zealand has been associated with the ingestion of wild pig. • The cause of GSM is unknown, although studies have demonstrated changes to the structure of mitochondria in affected dogs. • Aqueous and lipid extracts of liver from 24 normal dogs and 15 dogs with the myopathy were analysed by LC-MS. • No cause was identified, but several mass spectral features in GSM dogs could be consistent with plant-derived alkaloids. • The disease is associated with changes in the abundance of phospholipids, kynurenic acid and N-acetylated amino acids.

• ESBL or AmpC-E. coli were isolated from faecal swabs collected from companion animals, at a prevalence close to the prevalence of faecal carriage in humans. • Multivariable analysis identified variables independently associated with increased odds of ESBL-/AmpC-E. coli carriage in cats and dogs. The incidence of infections with extended spectrum β-lactamase producing Escherichia coli (ESBL-E) is increasing both in humans and animals. There is a paucity of data about the rate of faecal carriage of ESBL-E in pets. In this study, faecal swabs collected from 586 pets (225 cats; 361 dogs) in Auckland, New Zealand, were analysed for the presence of ESBL-E by culture, and a questionnaire was delivered to the owners. The ESBL-E were characterised and data elicited by the questionnaires were used for a multivariable analysis, to investigate the factors associated with faecal ESBL-E carriage. The prevalence of ESBL-E in faecal swabs was 6.4%. The β-lactamase genes detected in the ESBL-E were the blaCTX-M-14 (n = 2) and blaCMY-2 (n = 34). Several isolates displayed multilocus sequence types (ST) associated with human and animal infections. Multiple isolates sharing the same ST displayed different antibiograms and β-lactamase genes, reflecting horizontal gene transfer between and within ST. Variables independently associated with increased odds of ESBL-E carriage were: animal received systemic antimicrobial treatment in the six months before the sampling; presence of household members working in veterinary clinics; presence of household members travelling overseas in the six months before the sampling. We conclude that pets are colonised by ESBL-E which are genotypically similar to the bacteria found to infect humans and animals. The statistical analysis suggested a number of eco-epidemiological factors associated with ESBL-E carriage. In particular, they suggest veterinary clinics may represent hot-spots of antimicrobial resistance. [ABSTRACT FROM AUTHOR]

Aims: To assess the prevalence of obesity in adult dogs and cats presented to first-opinion veterinary clinics in the North Island of New Zealand for routine vaccination appointments, using electronic medical records. Methods: Ten first-opinion veterinary clinics across the North Island of New Zealand provided electronic medical records for all routine vaccination appointments for adult (>1 year old) dogs and cats between 1 January 2011 and 30 June 2016. Animals with a body condition score (BCS) of 6 or 7 on a 9-point scale and 4 on a 5-point scale were classified as overweight; those with a BCS of 8 or 9 on a 9-point scale and 5 on a 5-point scale were classified as obese. A total of 106,144 records were available over the study period, of which 48,041 (45.2%) had both a recorded weight and BCS. Results: Of the 24,247 records for dogs with both BCS and weight, 6,324 (26.1%) were classified as overweight, and 551 (2.3%) as obese. The prevalence of dogs classified as overweight or obese was highest in dogs aged between 5-13 years. The odds of desexed dogs being classified as overweight or obese was greater than the odds for intact dogs (OR=1.42 (95% CI=1.29-1.57), p<0.001) adjusting for the effects of age. Of the 23,794 records for cats with a recorded weight and BCS, 5,222 (21.9%) were classified as overweight, and 622 (2.6%) as obese. The prevalence of cats classified as overweight or obese was highest in cats aged between 5-11 years. The odds of desexed cats being classified as overweight or obese tended to be greater than the odds for intact cats (OR=1.14 (95% CI=0.98-1.31); p=0.075), adjusting for the effects of age. Conclusions: Although there are limitations with using electronic medical records to estimate the prevalence of obesity in companion animal populations, the results highlight that a significant number of animals presenting for routine vaccination appointments were classified as overweight or obese. Clinical Relevance: It is important for veterinarians to record both patient body condition and weight during routine preventative care appointments to allow accurate ongoing monitoring of trends in obesity at both the patient and population levels.

AIM: To conduct an epidemiological investigation of an idiopathic myopathy, known as “Go Slow” (GSM), which was initially recognised in dogs used for pig hunting. A secondary aim was to describe the hunting activities, diet and health of dogs used for pig hunting in New Zealand. METHODS: A retrospective cohort study was conducted between June 2014-June 2017. Cases of GSM in dogs were diagnosed by veterinarians using a combination of clinical history, physical examination findings, serum biochemistry and/or skeletal muscle histology. A telephone interview was conducted with the owner or primary veterinarian to provide information regarding the dog’s diet and exercise over the 7 days preceding the onset of clinical signs. In August 2015, a separate online survey of owners of dogs used for pig hunting was conducted to characterise the normal hunting activities, diet and health of these dogs. RESULTS: A total of 86 cases of GSM were recruited, of which 58 (67%) were pig hunting dogs, 16 (19%) pet dogs and 12 (14%) working farm dogs. Cases were most commonly reported in the upper North Island, and 65 (76 (95% CI=67-85)%) were from the Northland region. Processed commercial dog food had been fed to 93 (95% CI=88-98)% of affected dogs. Ingestion of raw, frozen or cooked wild pig in the preceding week was reported for 76 (88 (95% CI=82-95)%) dogs with the myopathy. In the survey of owners of healthy pig hunting dogs, 203 eligible responses were received; pig hunting was reported to most commonly occur in Northland (20.2%), Waikato (22.3%) and Bay of Plenty (23.2%) regions. Commercial dog food was fed to 172 (85 (95% CI=80-90)%) of the dogs included in this survey, and 55 (27 (95% CI=20-33)%) had eaten wild pig in the preceding week. The most common reported health problem in pig hunting dogs was traumatic wounds. CONCLUSIONS: Cases of GSM were most commonly recognised in dogs used for pig hunting, but also occurred in pet and working farm dogs. The disease was most frequently reported in the upper North Island of New Zealand and ingestion of wild pig was a consistent feature in cases of this myopathy. CLINICAL RELEVANCE: To minimise the risk of dogs developing this myopathy, it would seem prudent to avoid feeding any tissues from wild pigs to dogs in areas where the disease is known to occur.

AIMS: To survey current anaesthesia practices for dogs and cats in small and mixed animal practices in New Zealand in order to improve anaesthesia education. METHODS: A questionnaire was sent to 440 small and mixed animal practices, including questions regarding the type of practice, preanaesthetic examination, anaesthetic drugs and management, anaesthetic machines, monitoring and topics of interest for continuing professional development. RESULTS: Responses were obtained from 113/440 (26%) practices, with 78 (69%) respondents from small and 35 (31%) from mixed animal practices. A preanaesthetic physical examination was carried out by >95% of respondents and premedication was usually given to dogs (112/113; 99%) and cats (95/113; 85%). Acepromazine was the preferred sedative for dogs and cats, with morphine or buprenorphine. Propofol and alfaxalone were the preferred induction agents, and isoflurane was preferred for maintenance in both dogs and cats. A venous catheter was usually placed for anaesthesia in dogs (59/113; 52%), but less so in cats (39/113; 35%). Perioperative fluid was administered at 10 mL/kg/hour by 62/110 (56%) respondents. Intubation was usually used for anaesthesia in dogs (111/112; 99%), and cats (87/112; 78%). Almost 40% of respondents usually administered supplementary oxygen if patients were not intubated. Local analgesia was used by 69/111 (88%) respondents sometimes or always if applicable. Morphine or buprenorphine, and meloxicam were common choices for post-operative analgesia after neuter surgery in dogs and cats. A semiclosed (non-rebreathing) system was used in animals weighing <10 kg, and a Mapleson E or F non-rebreathing circuit was used by 66/109 (61%) practices. Only 15/111 (14%) practices had a ventilator in their practice. A dedicated anaesthetist was usually used by 104/113 (92%) practices, and apnoea alarms, pulse oximeters, thermometers and oesophageal stethoscopes were the main monitoring devices available in practices. Loco-regional block, pain management, and anaesthetic drugs were the main topics of interest for continuing education. CONCLUSIONS AND CLINICAL RELEVANCE: Responses by the veterinarians taking part in this survey indicated that they had a reasonably good standard of anaesthetic practice. A physical examination was carried out preanaesthesia, and premedication including analgesia was routinely administered to most patients. A dedicated anaesthetist usually monitored patients and most respondents reported they had access to basic anaesthetic monitoring equipment. Areas where changes could lead to improved anaesthetic practice were increased use of I/V catheterisation, endotracheal intubation, and supplementary oxygen, and reduced I/V fluid rates.

Objectives: Staphylococcus aureus skin and soft tissue infection (Sa-SSTI) places a significant burden on healthcare systems. New Zealand has a high incidence of Sa-SSTI, and here most morbidity is caused by a polyclonal methicillin-susceptible (MSSA) bacterial population. However, MSSA also colonise asymptomatically the cornified epithelia of approximately 20% of the population, and their divide between commensalism and pathogenicity is poorly understood. We aimed to see whether MSSA are genetically differentiated across colonisation and SSTI; and given the close interactions between people and pets, whether strains isolated from pets differ from human strains.Methods: We compared the genomes of contemporaneous colonisation and clinical MSSA isolates obtained in New Zealand from humans and pets.Results: Core and accessory genome comparisons revealed a homogeneous bacterial population across colonisation, disease, humans, and pets. The rate of MSSA colonisation in dogs was comparatively low (5.4%).Conclusions: In New Zealand, most Sa-SSTI morbidity is caused by a random sample of the colonising MSSA population, consistent with the opportunistic infection model rather than the paradigm distinguishing strains according to their pathogenicity. Thus, studies of the factors determining colonisation and immune-escape may be more beneficial than comparative virulence studies. Contact with house-hold pets may pose low zoonotic risk.

The introduction and subsequent rapid spread of Japanese encephalitis virus genotype IV across all Australian mainland states and the Northern Territory since late 2021 has increased the risk of an incursion of this mosquito-transmitted zoonotic virus disease into New Zealand, with serious implications for both animal and human health. The potential modes of entry are through introduction of infected mosquitoes as hitchhikers on ships or aircraft, windborne transfer of mosquitoes, or arrival of infected reservoir bird species. A competent vector mosquito, Culex quinquefasciatus , is endemic in New Zealand and other mosquito species may also become involved. If infection becomes established in New Zealand, the scale of transmission may be considerably less than has occurred in Australia because climatic and epidemiological factors are not so favourable. Early evidence of an incursion could come from detection of clinical disease in horses or pigs, or from human cases. Targeted surveillance to confirm or refute indications of an incursion could be undertaken by antibody detection in a number of species. Dogs have been shown to be a particularly valuable sentinel species due to their cohabitation with people and high seroconversion rate. Other novel methods of surveillance could include reverse transcriptase PCR (RT-PCR) on oronasal secretions of pigs. Should evidence of the disease be detected, prompt action would be required to vaccinate at-risk human populations and clarify the epidemiological situation with respect to mammalian hosts and mosquito vector species, including whether a new mosquito species had arrived in the country.

There has been a recent upsurge in human cases of leptospirosis in New Zealand, with wildlife a suspected emerging source, but up-to-date knowledge on this topic is lacking. We conducted a cross-sectional study in two farm environments to estimate Leptospira seroprevalence in wildlife and sympatric livestock, PCR/culture prevalence in wildlife, and compare seroprevalence and prevalence between species, sex, and age groups. Traps targeting house mice (Mus musculus), black rats (Rattus rattus), hedgehogs (Erinaceus europaeus) and brushtail possums (Trichosurus vulpecula) were set for 10 trap-nights in March-April 2017 on a dairy (A) and a beef and sheep (B) farm. Trapped wild animals and an age-stratified random sample of domestic animals, namely cattle, sheep and working dogs were blood sampled. Sera were tested by microagglutination test for five serogroups and titres compared using a Proportional Similarity Index (PSI). Wildlife kidneys were sampled for culture and qPCR targeting the lipL32 gene. True prevalence in mice was assessed using occupancy modelling by collating different laboratory results. Infection profiles varied by species, age group and farm. At the MAT cut-point of ≥ 48, up to 78% of wildlife species, and 16-99% of domestic animals were seropositive. Five of nine hedgehogs, 23/105 mice and 1/14 black rats reacted to L. borgpetersenii sv Ballum. The sera of 4/18 possums and 4/9 hedgehogs reacted to L. borgpetersenii sv Hardjobovis whilst 1/18 possums and 1/9 hedgehogs reacted to Tarassovi. In ruminants, seroprevalence for Hardjobovis and Pomona ranged 0-90% and 0-71% depending on the species and age group. Titres against Ballum, Tarassovi and Copenhageni were also observed in 4-20%, 0-25% and 0-21% of domestic species, respectively. The PSI indicated rodents and livestock had the most dissimilar serological responses. Three of nine hedgehogs, 31/105 mice and 2/14 rats were carrying leptospires (PCR and/or culture positive). True prevalence estimated by occupancy modelling in mice was 38% [95% Credible Interval 26, 51%] on Farm A and 22% [11, 40%] on Farm B. In the same environment, exposure to serovars found in wildlife species was commonly detected in livestock. Transmission pathways between and within species should be assessed to help in the development of efficient mitigation strategies against Leptospira., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Moinet et al.

Objectives: (1) To explore the relationship between regionally implemented dog control strategies and dog bite injuries (DBIs) and (2) to evaluate current implementation of dog control strategies., Methods: Observational study using a nationwide online survey of territorial authorities (TAs). Domains of interest included complaints for attacks on people, dog population, primary and secondary prevention strategies, resourcing and perspectives of current strategies. Quantitative variables were compared with DBI Accident Compensation Corporation (ACC) claims by region from 2014 to 2018., Results: Two-thirds of TAs (70%; n=47/67) responded to the survey. No clear relationship was observed between DBIs and: registered dog population, proportion sterilisations or microchipping, classifications due to dog behaviour, or existing limited resourcing. Legislated breeds and infringements for failure to control a dog or non-registration were higher in areas with greater DBIs. Educational messages varied widely and were predominantly victim directed (67%; n=71/106). Complaints for dog attacks on people were lower than DBIs in most areas, with no formal cross-agency notification policies. Few prosecutions or dog destruction orders were made., Conclusions: Regional inequity in DBIs could not be explained by differences in the registered dog population or dog control strategies. Minimal and inequitable resourcing exists to implement current dog control strategies and provide owner-directed education. Gaps in legislation include environmental barrier requirements for all dogs (leash/muzzle use, adequate fencing), notification of incidents and child protection. Partnership with the Indigenous community (Māori) and other community groups will be required to implement these measures successfully., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

AIM: To survey the attitudes and perceptions of veterinary paraprofessionals in New Zealand to postoperative pain in dogs and cats. METHODS: In December 2011, veterinary paraprofessionals (VP) from throughout New Zealand were invited to participate in an online survey. Eleven questions, which were divided into five sections, were used to determine demographic information, the respondents’ assessment of pain after commonly performed surgeries in dogs and cats, their opinions on provision of analgesia, who had responsibility for pain monitoring and the use of any formal pain scoring system in the practice. RESULTS: Data from 165 respondents were able to be used, and 162 (98%) respondents to the survey were female. According to the respondents’ estimates, fracture repair in dogs and repair of diaphragmatic hernias in cats had the highest pain score following surgery. Neutering procedures involving dogs were scored higher than for cats (p<0.01). All respondents agreed that animals benefit from perioperative analgesia. The veterinary nurse was reported to be predominantly responsible for monitoring pain in animals postoperatively by 116/165 (70.3%) respondents. Of 165 respondents, 154 (93%) considered that their knowledge of pain and assessment of pain could be enhanced. CONCLUSIONS: This survey reflects the attitudes and perceptions of a sample of VP in New Zealand to postoperative pain in dogs and cats. The results indicate that all respondents believe that surgery results in sufficient pain to warrant analgesic therapy. Routine neutering surgeries were considered to be more painful in dogs than in cats. The current survey also provides information to educators on potential areas of focus, given that 93% of respondents felt that their knowledge of pain and assessment of pain could be enhanced.

Aims: To examine and assess causes of mortality of kiwi ( Apteryx spp.) submitted to Massey University between 2010 and 2020 across the five recognised species according to location, age group and captivity status in New Zealand., Methods: Post-mortem reports were obtained from the Massey University/Te Kunenga ki Pūrehuroa School of Veterinary Science/Wildbase Pathology Register. Inclusion criteria were all species of kiwi with a date of post-mortem examination between August 2010 and August 2020. Data from each report was exported, categorised and compared using Microsoft Excel., Results: Of a total of 1,005 post-mortem reports, there were 766 North Island brown kiwi (NIBK; A. mantelli ), 83 tokoeka ( A. australis ), 73 rowi ( A. rowi ), 49 great spotted kiwi ( A. haastii ), and 34 little spotted kiwi ( A. owenii ). This comprised 19 eggs/embryos, 125 neonatal, 473 juvenile, 153 subadult, and 235 adult kiwi. There were 615 kiwi from wild populations, 148 from sanctuary populations, 238 from captivity, and four from unspecified locations. The leading cause of death was trauma, affecting 322 (32.0 (95% CI = 29.2-35.0)%) kiwi including 289 (37.3 (95% CI = 26.0-31.7)%) NIBK. Nearly half of these died from predation by mustelids, with losses recorded from neonates to adults and clustered in the central to southern North Island. Predation by dogs was the second most common cause of death, killing 84 (8.4 (95% CI = 6.7-10.2)%) kiwi, of which 65.5% came from the northern districts of the North Island. Non-infectious disease killed 214 (21 (95% CI = 18.8-24.0)%) kiwi, and included developmental deformities, gastrointestinal foreign bodies and predator trap injuries. Infectious disease killed 181 (18.0 (95% CI = 15.7-20.5)%) kiwi and the proportion decreased with age, with common diagnoses including coccidiosis, bacterial septicaemia, avian malaria, and fungal respiratory disease. Starvation affected 42 (4.2 (95% CI = 3.0-5.6)%) kiwi, comprised of mainly neonatal or juvenile individuals from wild or sanctuary populations, with a higher percentage seen in tokoeka (11/83; 13.3%) compared to other species (min 0%, max 5.9%). The cause of death was undetermined in 246 (24.5 (95% CI = 21.8-27.3)%) cases, which was most often due to poor preservation of remains. This included 33/73 (46%) rowi and 32/83 (39%) tokoeka, and affected mainly birds from sanctuary and wild populations., Conclusions: This study enhances our understanding of causes of mortality in captive, wild and sanctuary populations of all kiwi species and age groups within contemporary New Zealand.

Aims: To investigate the frequency of carriage of methicillin-susceptible and methicillin-resistant Staphylococcus pseudintermedius (MRSP) in a population of clinically normal dogs within the Christchurch and wider Canterbury region, an area in which MRSP has been detected., Methods: Buccal and perianal swabs were collected from 126 clinically normal dogs presenting at veterinary clinics in the Christchurch/Canterbury region for de-sexing or routine vaccination. S. pseudintermedius was isolated by selective culture. Isolates were tested for susceptibility to 12 antimicrobials by disc diffusion., Results: S. pseudintermedius was isolated from 92/126 (73.0 (95% CI = 64.4-80.5)%) dogs, with 38/126 (30.2 (95% CI = 22.3-39.0)%) positive dogs carrying S. pseudintermedius at both sampled sites. More animals (78/126; 61.9 (95% CI = 52.8-70.4)%) had positive mouth cultures than positive perianal region cultures (52/126; 41.3 (95% CI = 32.6-50.4)%). No MRSP was isolated from clinically normal dogs. However, resistance to penicillin (106/130 (85.1%) swabs) and tetracycline (33/130 (25.4%) swabs) was seen., Conclusions: The majority of the dogs in this sample were carriers of S. pseudintermedius . However, none of these isolates were MRSP., Clinical Relevance: While most clinically normal dogs in the studied region are likely to be carriers of S. pseudintermedius , only a small proportion, if any, are likely to be carriers of MRSP. Antibiotic stewardship practices may be important to maintain low-level circulation of drug-resistant bacterial lineages.

AIMS: To investigate public attitudes towards barking dogs in New Zealand in order to quantify the extent to which people perceive barking dogs to be a problem, to compare tolerance of barking with that of other common suburban noises, to assess the level of public understanding about the function of barking, to determine risk factors for intolerance of barking and to assess knowledge of possible strategies for the investigation and management of problem barking. METHODS: A 12-page questionnaire was sent to 2,000 people throughout New Zealand randomly selected from the electoral roll. Risk factors for being bothered by barking were examined using logistic regression analysis. RESULTS: A total of 1,750 questionnaires were successfully delivered; of these, 727 (42%) were returned. Among respondents, 356/727 (49.0%) indicated that frequent barking during the day would bother them while 545/727 (75.0%) would be bothered by barking at night. Barking and howling were ranked above other suburban noises as a cause of annoyance. Risk factors for being bothered by daytime barking were not being home during the day, not owning a dog, and considering a dog bite to be a serious health risk. Risk factors for being bothered by night-time barking were not being home during the day, marital status, considering dog bites to pose a serious health risk, and having been frightened by a dog. Overall, 510/699 (73%) respondents understood that barking was a form of communication. Action likely to be taken by 666 respondents hearing frequent barking included notifying and offering to help the owner (119; 17.8%), complaining to the owner (127; 19.1%) or the authorities (121; 18.2%), or doing nothing (299; 48%). Possible responses by 211 dog owners if they had a barking dog included seeking help from dog trainers (59; 28%) or behaviourists (54; 26%), buying an anti-barking device (33; 15%) or getting rid of the dog (20; 10%). CONCLUSIONS: Barking was considered to be potentially disturbing by respondents to this survey. Attitudes towards barking were most influenced by age, dog ownership, past experience with dogs and attitude towards dog bites. Public understanding of the possible reasons for barking and appropriate methods of managing the behaviour when it becomes a problem could be improved by better education and the provision of information through veterinary clinics and social media.

Abstract: Objectives: To investigate the psychosocial effects of the companion robot, Paro, in a rest home/hospital setting in comparison to a control group. Design: Randomized controlled trial. Residents were randomized to the robot intervention group or a control group that attended normal activities instead of Paro sessions. Sessions took place twice a week for an hour over 12 weeks. Over the trial period, observations were conducted of residents’ social behavior when interacting as a group with the robot. As a comparison, observations were also conducted of all the residents during general activities when the resident dog was or was not present. Setting: A residential care facility in Auckland, New Zealand. Participants: Forty residents in hospital and rest home care. Measurements: Residents completed a baseline measure assessing cognitive status, loneliness, depression, and quality of life. At follow-up, residents completed a questionnaire assessing loneliness, depression, and quality of life. During observations, behavior was noted and collated for instances of talking and stroking the dog/robot. Results: In comparison with the control group, residents who interacted with the robot had significant decreases in loneliness over the period of the trial. Both the resident dog and the seal robot made an impact on the social environment in comparison to when neither was present. Residents talked to and touched the robot significantly more than the resident dog. A greater number of residents were involved in discussion about the robot in comparison with the resident dog and conversation about the robot occurred more. Conclusion: Paro is a positive addition to this environment and has benefits for older people in nursing home care. Paro may be able to address some of the unmet needs of older people that a resident animal may not, particularly relating to loneliness. [Copyright &y& Elsevier]

Abstract: Dogs (Canis familiaris) pose a significant threat to kiwi (Apteryx spp.) through predation. In an attempt to balance kiwi conservation and the need for dogs to be used for hunting purposes in kiwi habitat, the New Zealand Department of Conservation (DOC) developed the Kiwi Aversion Training (KAT) programme. KAT involves a training session in which a dog is presented with KAT stimuli (stuffed kiwi, frozen kiwi, and kiwi feathers) and a brief period (0.5–1.5s) of aversive electrical stimulation from an electric shock collar is applied when the dog makes contact with the training stimuli. This paper reports three experiments: (1) investigating whether dogs can learn to avoid the KAT stimuli through aversion training; (2) investigating maintenance of aversion to the KAT stimuli 1 month after initial training; and (3) investigating maintenance of aversion to the KAT stimuli 1 year after initial training. All dogs showed aversion responses to the KAT stimuli during the initial KAT training and also when exposed to the KAT stimuli 1 month after training without an electric collar being worn. 1 year after initial training, 87% (48/55) of dogs avoided the KAT stimuli. This research indicates that KAT effectively produces aversion towards the KAT stimuli that generalizes to another location, is independent of the electric collar being worn, and that lasts at least 1 year after training.

The article discusses a study of the prognosis for a return to work of working farm dogs in New Zealand that underwent partial tarsal arthrodesis (PTA). The researchers identified 14 dogs using medical records of Masset University Veterinary Teaching Hospital and Veterinary Specialist Orthopaedic Services and assessed their ability to work after surgery. They found that 50 percent of the dogs could go back to work duties after undergoing PTA.

The article describes the case of an eight-year-old female, spayed Border Collie which was taken to the Massey University Veterinary Teaching Hospital in New Zealand because of coughing, choking, and haemoptysis. The dog was diagnosed of having extramedullary plasmacytoma of the larynx and treated with melphalan and predisolone. After six months of chemotherapy, the tumor reappeared and euthanasia was performed.

The article presents a study which examined whether there has been considerable improvement in the phenotypic hip dysplasia status in four susceptible dog breeds as measured by the New Zealand Veterinary Association (NZVA) Canine Hip Dysplasia scheme. A retrospective analysis of the NZVA on records of all four dog breeds that were evaluated for hip dysplasia was conducted. The impact of date of birth on total hip score was determined. No significant improvement in three out of the four breeds was found.

The article presents information on a research study which investigated the behavioral responses of dogs and cats to fireworks in New Zealand. Data collection was through a questionnaire aimed at dog and cat owners distributed via the "Animals Voice" journal and 25 veterinary clinics. Survey topics include demographics of animals, fear of fireworks, severity of the fear and exhibited behaviors, among others. A discussion on the research findings is detailed.
