are not the only ones with this unique property. If you’ve ever seen a Chow Chow, you’ve probably noticed their unique blue-black tongue. Chow Chows and Chinese Shar Peis actually require a blue and black tongue in their breed standard.
Pigment spots on your dog’s tongue are usually nothing to worry about. These darker spots are probably the result of microscopic granules of melanin appearing as flat, pigmented areas on your dog’s tongue, just like a human can have freckles or birthmarks.
The Chow’s blue tongue makes it unique in the canine world, with one exception: the Chinese Shar-Pei. As with the Chow-Chow, the Shar-Pei breed standard requires bluish-black pigmentation on the mouth and tongue, with exceptions for diluted colors which may show lavender pigmentation.
Some dogs have naturally black gums or black spots in their mouths due to pigment differences. German shepherds and pit bulls are two examples. Other dogs, such as the Chow-Chow and Great Pyrenees, have black roofs in their mouths, also due to natural pigment differences.
Unlike dogs that have an all-black tongue, like Chow-Chow and Shar-Pei, the patches on a German Shepherd’s tongue are typically small. Many breeds can have these spots, but most of them are dogs that also have some black fur or spots, but this is not always the case.
Many breeds are known for displaying spotted tongues, but there are six dog breeds that are known for their black tongues, making them particularly unique.
The Chow-Chow, for example, has a purple or purple-spotted tongue.
You’re no doubt wondering if you should be concerned about that black coloration on your Labrador Retriever’s tongue. Black tongue markings don’t mean your dog isn’t purebred, and it doesn’t mean he’s ill. You don’t need to fret. Many healthy purebred Labradors have black spots on their tongue.
