This tumor usually affects the dog's genitals. Cases of damage to the mouth and nose are more rare. In appearance, the tumor often resembles a cauliflower.
As it turned out, lesions of the mouth and nose are stillmore common in males. Researchers believe this is due to behavioral differences: males spend more time sniffing and licking the females' genitals.
In the study, the researchers looked at a database of nearly 2,000 cases from around the world and found that only 32 tumors affected the nose or mouth. Of these, 27 cases were in males.
