Any idea what these are? What should be done to confirm your suspicion? Prognosis? Treatment?
This dog has viral papillomas, which was confirmed by biopsy. These were initially removed with only topical anesthetic, since they were attached by narrow stalks, but this would not always be possible. Viral papillomas tend to recur, however, and this dog was no exception. They eventually spontaneously resolve, but oral azithromycin has been suggested as a means of encouraging prompter resolution.
