Does your dog have a black or bluish spot on their tongue?
These spots can appear black or blue and have the same texture as the rest of your dog's tongue. Dogs can be born with these spots or they can appear when they are young. As your dog ages, these spots can change shape and color over time.
Like human birthmarks and freckles, spots on a dog's tongue are just deposits of extra pigments. These pigments can be found on their gums and also under their coats.
Dogs are not the only ones that have black spots in their mouths. Polar bears, giraffes, and certain breeds of cattle also can have blue or black spots on their tongue.
Are black spots a problem?
As mentioned, these spots are most often just pigmented spots on your dog's tongue. If however, the spots have a foul odor, are bumpy, or don't look like a part of your dog's skin, you should contact your vet.
Dog Breeds That Have Blue/Black Tongues
The black spots on their tongue are most commonly associated with the Chow Chow and Chinese Shar-Pei.
Some people falsely believe that if your dog has a spot on their tongue, they are not a purebred or are part Chow Chow. This is not true. It's just extra pigments of melanin.
More than 30+ dog breeds have spotted tongues. These spots can appear in any breed of dog, but are most common with breeds that have black coloring in their noise, eyes, lips, paw pads, and toenails.
The following is a list of dog breeds that have been known to have black spots on their tongues:
Australian Cattle Dog
Bull Mastiff, Cairn Terrier
Chinese Shar Pei
Flat Coated Retriever
At the end fo the day, I believe we can call the myths about dogs with spots on their tongues exactly that... Myths.
That said, we may as well toss one more possible reason for the dark spots into the mix for everyone to consider.
Maybe golden retrievers have evolved to now come with a "place treat here" spot on their tongue to help new owners!
