Human papillomaviruses (HPVs) are well-known for causing both benign and malignant epithelial growths in humans, but their occurrence in non-human species is rarely reported. In our investigation of serum samples from dogs collected in Guangxi, China, between 2014 and 2020, we unexpectedly detected two strains of HPV with a detection rate of 0.16% (2 out of 1226 samples). Phylogenetic analysis reveals that the canine-origin HPV strain GX-70 is grouped within the same evolutionary branch as alpha2-HPV78, while GX-47 is positioned in the same clade as alpha2-HPV94. Interestingly, both strains displayed multiple amino acid variations. Although virus isolation was not achieved, the detection of HPV nucleic acids suggests the potential presence of HPV in canine hosts. These findings provide new insights into the possible host range of HPV, underscoring the need for further research to assess the virus's infectivity, transmission dynamics, and potential implications for both animal and human health.
