A new type of parvovirus known as feline chaphamaparvovirus (FeChPV) was discovered in the feces of shelter cats in Canada in 2019, and >50% of cats were reported to be infected with this virus. In this study, two FeChPV-positive samples were identified from the rectal swabs of 285 dogs with diarrhea but none in 50 healthy dogs. Whole genome sequences of these two FeChPV strains (OQ162042 and OQ162043) were amplified and compared with those of the two viruses originally discovered in Canada (IDEXX-1 and VRI849). The whole genome, NS1, and VP1 of the two FeChPV strains shared a high identity of 95.0%–97.8% nucleotide, 96.9%–98.6% amino acid (aa), and 97.2%–98.8% aa with the reported FeChPV strains, respectively. The phylogenetic tree of NS1 and VP1 revealed that two FeChPV strains, namely, CHN20201025 and CHN20201226, were closely clustered with the two FeChPV prototypes detected in Canada in a group. Moreover, CHN20201025 and CHN20201226 were obviously different from Carnivore chaphamaparvovirus 1 and were classified as Carnivore chaphamaparvovirus 2. This is the first study to report the identification of FeChPV in fecal samples from dogs in China, and the genetic analysis of the FeChPV, which was previously detected in Canadian cats, would improve our understanding of its host spectrum.
