Background: Beagles are a popular companion animal dog breed and are generally stated to be a healthy breed. This VetCompass study aimed to report the demography, common disorders and mortality of Beagles under primary veterinary care in the UK. Anonymised clinical records within VetCompass were followed over time to extract disorder and mortality data during 2019 on Beagles under primary veterinary care in the UK. Results: Beagles comprised 19,906 (0.88%) of the 2,250,417 dogs in the study population. Annual proportional birth rates showed an increasing breed popularity from 0.41% of all dogs born in 2005 and peaking at 1.06% in 2012, followed by a decrease to 0.90% in 2019. The median adult bodyweight was 18.19 kg (IQR 15.68–21.07). From a random sample of Beagles (3,729/19,906, 18.73%), the most diagnosed disorders were obesity (24.27%, 95% CI: 22.89–25.65), periodontal disease (17.78%, 95% CI: 16.55–19.01), overgrown nail(s) (11.61%, 95% CI: 10.58–12.64), otitis externa (11.18%, 95% CI: 10.17–12.19) and anal sac impaction (10.59%, 95% CI 9.60-11.58). Once disorders were grouped by pathology, the most common group-level disorders were obesity (24.27%, 95% CI: 22.89–25.65), dental disorders (21.48%, 95% CI: 20.16–22.80), ear disorders (13.62%, 95% CI: 12.52–14.72), claw/nail disorders (13.14%, 95% CI: 12.06–14.22) and anal sac disorders (11.10%, 95% CI: 10.09–12.11). The median age at death was 11.28 years (IQR 9.32–13.08) for 322 deaths recorded during the study period. The most common causes of death at group level were neoplasia (19.26%, 95% CI: 14.76–23.75), mass (13.18%, 95% CI: 9.32–17.03), poor quality of life (12.84%, 95% CI: 9.03–16.65), and brain disorders (6.76%, 95% CI: 3.90–9.62). Conclusions: Their disorder profile suggests the Beagle breed should not be considered to have an extreme conformation. Owners and veterinary teams should put special emphasis on care related to bodyweight control and dental hygiene in Beagles. Their median age at death of 11.70 years suggests reasonable overall health but neoplasia is a common biomedical cause of death in Beagles. Plain English summary: The Beagle is a scenthound originally created to hunt hare but that is now more commonly kept as a companion dog breed. The Beagle is promoted as a generally healthy dog but there is limited published evidence of the health of the subset of the breed that is owned outside of laboratory research. This VetCompass study aimed to report on the demography, common disorders and mortality of Beagles under primary veterinary care in the UK. VetCompass collects anonymised veterinary clinical records for research on canine health. Beagles comprised 0.88% of the 2,250,417 dogs in the current study under veterinary care during 2019 in the UK. The average adult bodyweight of Beagles was 18.19 kg. Male Beagles were on average over 3 kg heavier than female Beagles (19.70 kg vs. 16.59 kg). From a random sample of 3,729 Beagles whose clinical records were examined in more detail, the most common disorders diagnosed were obesity (24.27% of all Beagles affected in 2019), dental disease (17.78%), overgrown nail(s) (11.61%), ear infection (11.18%) and anal sac impaction (10.59%). From 322 dogs that died during the study, the average age at death was 11.28 years. Females outlived males by almost a year (11.70 years vs. 10.75 years). The most common general causes of death were cancer (19.26%,), lumps (13.18%), poor quality of life (12.84%) and brain disorders (6.76%). These results confirm the Beagle as a generally healthy breed, with a lifespan and disorder profile similar to dogs overall. However, owners and veterinary teams should put special emphasis on care related to bodyweight control and dental hygiene in Beagles. [ABSTRACT FROM AUTHOR]
