What Dog Breeds Have Black on the Roofs of Their Mouth?

The chow chow, the Pyrenean mountain dog, the Pyrenean shepherd, and the Estrela mountain dog all have a black palate. The black palate is a hereditary trait caused by melanin granules, which are darker skin pigments.

It is believed that melanin is the skin’s natural response to ultraviolet radiation because it can disperse about 99.9 percent of UV rays. As a dog ages, it is usual for these malinin regions to expand to the tongue or alter shape. However, it is essential to frequently inspect these malinin sites for lumps or elevated surfaces. Normal malinin regions should be flat and smooth. As this may be an indication of melanoma, dogs with rough or elevated malinin surfaces should be taken to a local veterinarian as soon as possible. If a black tongue or gums are observed in a dog breed that is not prone to this physical condition, it is equally vital to consult a veterinarian.

This hue could potentially be the result of cyanosis. Cyanosis is the darkening of the tongue, gums, or palate caused by insufficient blood oxygen circulation. Cyanosis may be a sign of cardiovascular or respiratory illness. Any dog exhibiting cyanosis signs must be checked immediately by a veterinarian.
