Melanoma is the most common tumor found in the mouth of dogs, and the second most common tumor found is on the digits (toes). There is a predisposition for male dogs and certain breeds seem to be overepresented, including Scottish terriers, Cocker Spaniels, Gordon Setters, Chow Chows, and Golden retrievers. They are locally invasive tumors, often infiltrate deep into the bone (of the jaw or toe), and have a high rate of metastasis (spreading). Cats can also get melanomas but it is much less common than in the dog.
