The fascinating world of dog breeds boasts a remarkable array of colors, shapes, and sizes. But have you ever stopped to consider the color of a dog’s tongue? While most dogs sport pink tongues, certain breeds stand out with a unique blue-black hue. So, what dog breeds have blue tongues? This article delves into this intriguing characteristic, exploring the breeds known for their blue tongues, the genetic reasons behind this unique trait, and any associated health implications.
The most well-known breed with a blue tongue is the Chow Chow. Originating from China, these majestic dogs are instantly recognizable by their lion-like mane and distinctly blue-black tongues. The intensity of the blue can vary, ranging from a dark slate to a lighter lavender. However, it’s important to note that not all Chow Chows are born with a fully blue tongue; puppies are born with pink tongues that gradually darken to blue-black as they mature.
Other Breeds with Blue Tongues
While the Chow Chow is the most prominent example, a few other breeds also exhibit this unique trait. The Chinese Shar-Pei, known for its wrinkled skin, also boasts a blue-black tongue, further suggesting a possible genetic link between the two breeds.
The Shar-Pei Connection
Like the Chow Chow, the Chinese Shar-Pei’s tongue color deepens as they grow older. This shared characteristic reinforces the theory of a common ancestry or genetic link between these two ancient Chinese breeds.
The Genetics Behind Blue Tongues
The exact genetic mechanism responsible for blue tongues in dogs isn’t fully understood. However, it is believed that a dominant gene controls the production of melanin, the pigment responsible for coloration in skin, hair, and eyes, and in this case, the tongue. This increased melanin production results in the characteristic blue-black pigmentation.
Melanin and Pigmentation
Melanin plays a crucial role in determining an organism’s coloration. In dogs with blue tongues, the higher concentration of melanin in the tongue tissue results in the distinctive blue-black color. This is similar to how melanin affects the color of a dog’s nose or coat.
Health Implications
Generally, a blue tongue in the breeds mentioned above is a normal characteristic and doesn’t indicate any health issues. However, a sudden change in tongue color in any dog breed warrants a visit to the veterinarian. It could be a sign of an underlying health problem requiring immediate attention.

Are There Any Myths Associated with Blue Tongues?
One persistent myth suggests that dogs with blue tongues have colder tongues. This is simply untrue. Tongue temperature is not related to color. Another myth is that breeds with blue tongues are more susceptible to certain diseases. Again, this lacks scientific basis.
“A blue tongue is a breed-specific trait, not an indicator of health problems,” says Dr. Emily Carter, DVM. “Regular veterinary check-ups are essential for all dogs, regardless of tongue color.”
Conclusion
The blue tongue in certain dog breeds, primarily the Chow Chow and Chinese Shar-Pei, is a fascinating genetic trait. While the precise genetic mechanism remains somewhat of a mystery, it’s a harmless characteristic that adds to the unique appeal of these breeds. While the blue tongue itself doesn’t pose health concerns, any sudden change in tongue color should always be checked by a veterinarian.
