The incubation period for HPV ranges from 1 to 6 months; however, latency periods of up to 3 years or more are suspected. The lesions are present for several months and usually regress spontaneously within two years, although some may persist indefinitely.

This is a relatively short incubation period that is similar to that of influenza infection in other species.However, it is shorter compared to other causes of acute respiratory disease in canines, such as canine distemper and Bordetella bronchiseptica.his is a relatively short incubation period that is similar to that of influenza infection in other species.
