“Sound Medicine” healthy pet expert Liz Murphy, DVM, joins host Barbara Lewis in the studio to talk about why cats and dogs are at risk for melanoma. According to Dr. Murphy, melanoma in pets has nothing to do with sun exposure. Tumors in the mouth and between the toes on pets usually indicate melanoma. Catching melanoma early in pets, as well as in humans, is key to survival because melanoma metastasizes quickly. Establishing a quick once-over routine with your pet can help detect tumors quickly.
