The Genetics of Black Tongues in Dogs

The Role of Melanin

To comprehend why certain dogs have black tongues, we must first explore the role of melanin, the pigment responsible for various colors in animals, including humans and dogs. Melanin is produced by special cells called melanocytes. In dogs with black tongues, these melanocytes produce a higher concentration of melanin, resulting in the dark pigmentation.

Breeds with Black Tongues

While the majority of dog breeds possess pink tongues, several breeds stand out for their distinctive black tongues. The most well-known breed associated with black tongues is the Chow Chow. This ancient Chinese breed is renowned for its lion-like appearance and deep blue-black tongue. Other breeds with black tongues include the Shar-Pei, Thai Ridgeback, Labrador Retriever, and Eurasier. It’s worth noting that not all members of these breeds have black tongues, as tongue color can vary within a breed.

Common Misconceptions

Connection to Chow Chows

One prevalent misconception is that only Chow Chows have black tongues. While Chow Chows are indeed the breed most commonly associated with black tongues, other breeds can also exhibit this trait. It’s important to recognize that tongue color alone is not an accurate indicator of breed purity or mix.
