With currently 226 distinct characterized human papillomaviruses (hpvs), the majority of the established papillomavirus (pv) diversity is isolated from humans [1]. The involvement of this viral type in oral oncogenesis has been hypothesized in oral squamous cell carcinomas (sccs), but has never been investigated in other neoplastic and hyperplastic oral lesions of dogs.

Animal pvs cause distressing diseases in both farm and companion animals, such as teat papillomatosis in cattle, equine sarcoids and canine oral papillomatosis and there is an urgent need to understand the pathogenesis of these problematic infections.

Canine papillomavirus is spread by direct contact between an infected dog and a susceptible dog. It is now known that many genetically different papillomaviruses infect human beings, that specific types have predilections for particular anatomical sites, and certain types are known to be associated with lesions that progress to carcinoma.
