How unusual is a black spot on dog’s tongue?

Black spots on the tongue of a usually pink tongue dog breed like the Labrador are not actually that rare.

Many dogs have a spot or two on their tongue, just like many people have a mole or freckle or two on their arms.

What do dog black tongue spots look like?

The spots may almost cover the tongue, they may be well defined separate spots, or they may be a single large patch of color.

Dogs with black spots on tongue – labs are not the only breed

Black tongue spots are common in a number of breeds, not just in Labradors. Golden Retrievers get them too, as do German Shepherd Dogs.

In fact tongue spots occur regularly in over thirty different breeds of dog

When is a dog tongue spot harmful?

The surface of tongue spots that are caused by harmless pigmentation, or color changes, don’t feel different to the touch.

The spots are simply a different color from the pink areas of your dog’s tongue. 

The color you will see in this case is usually black, or a dark grey or blue grey, or bluish black. It will have been there from birth or have developed when your puppy was very young.

Any other color may have a different cause and needs bringing to the attention of your veterinarian. Tongue spots that develop in the older dog may be a cause for concern, and should be checked out by a vet.

If any parts of your dog’s tongue are raised or unusually smooth and shiny it is a good idea to have a chat with your vet about it. It may be nothing important, but it could be a health problem that needs treating.

Regular dental checks with your vet will help highlight any problems with your dog’s tongue but in the meantime, always consult your vet about any changes in your dog’s mouth.  Your vet won’t mind if there is nothing wrong, and problems spotted early on are much easier to treat.

What causes black spots on a dog’s tongue

The harmless dark spots that occur in some individuals in many dog breeds are caused by a pigment called melanin.

Find out all about black spots on a dog's tongueIt’s the same pigment that colors a black Lab’s fur and that causes darker skin in people.

Why does my dog have black spots on his tongue

According to the AKC

“While the random spots on the tongue of other breeds is just a result of heavy pigmentation carrying over to the tongue from the black points”

This may explain why a black Lab and other dark furred dogs might have dark tongue spots, but it clearly isn’t the whole story and many pale furred dogs, or dogs without black points, have tongue spots too.

The gene for pigmentation on the tongue is obviously capable of being expressed separately.

While it is likely that dog tongue spots are inherited we don’t know exactly how the mechanism of inheritance works.

If your dog has black tongue spots it is possible that one of your dog’s parents or grandparents had tongue spots too. But it isn’t a given, and tongue spots may appear in a dogs whose ancestors were spot-free.

What do black spots on a dog’s tongue mean

All this tells us that black spots on a dogs tongue doesn’t mean very much at all.

It doesn’t mean that there was a Chow in your dog’s family tree.

It doesn’t even mean he isn’t pure bred – many pedigree dogs have black tongue spots.

And provided the spots have always been there, and are not raised, changing shape or different in texture from the rest of his tongue, they are harmless

Just accept it as a delightful quirk in your dog’s appearance and part of his own character and individuality.

  1. My lab Delaney had 2 black spots one in the centre near the front and one further back which you only really saw after he’d been chasing his ball and he was worn out needing a drink lol

  2. My 8 month old lab cross has developed bluish black spots on his tongue that I am sure were not there when we got him at 6 weeks old. He’s a very healthy pup and the spots aren’t raised or anything, but seeing them gave me cause for concern

  3. We got our Sadie Sue, Lab Sheherd (NOT CHOW!) Mix, 12 and a half years ago when she was six months. (we had her 13th b’day cake last week) she is nearing the end of her long happy busy life and just today on this site I discovered that, black spotted tongue and all, she has NO Chow in her! Holy cow! She has been my best friend – and shadow- for many lovely years!

  4. My chocolate lab mix, 8 mos, has not barked since I adopted her 3 1/2 months ago. Does that mean she can’t bark? She is very submissive, afraid of everything, even me after 3 1/2 months. I wouldn’t hurt an animal for all the money in the world. Please answer me on e-mail.

  5. My pedigree field black lab has a black tongue spot quite far back on one side, she has a matching black spot in her ear on the same side. I like them as a little quirk of her and also a “Lassie” style way of identifying her if her legal “owner” was ever in question (she’s chipped, but I like the idea of dramatically proving she’s mine by my knowledge of her hidden anatomy lol)
