If you have noticed a black spot on your dog’s tongue, it is important that you get some information before rushing to any conclusions. 

While it is natural to worry when you find a strange looking blemish on your dog, you’ll want to get the facts first.

Importance of Checking Your Dog’s Mouth

Most veterinarians will recommend that dog owners check the inside of their pet’s mouth once in a while. A simple visual infection of your dog’s mouth can help you keep them healthy over the years. 

You’ll want to look for things like swollen gums, broken teeth, and strange-looking spots on their tongue, roof or sides of their mouth. All of these things can indicate a serious issue that may require treatment.

The sooner you discover something that doesn’t look right, the sooner you will be able to find out what is really going on. Your veterinarian should be able to give you a definitive answer.

Appearance of the Black Spots

These black spots will most likely be consistent with every other part of their tongue in terms of texture. You might want to run your finger along with the spot just to make sure.

These spots are a natural part of your dog’s tongue. It is normal for these spots to become larger or smaller over time. They may even become a slightly different shape.

When to See Your Veterinarian

It is very possible that the black spots on your dog’s tongue are perfectly harmless, but there are a few things to watch out for. If you notice that the spots have changed in shape and/or size over a short period of time, you’ll want to take your dog to the vet. This could be a sign of cancer, but not necessarily.

You’ll also want to go see your vet if the black spot has a different texture/feel than the rest of their tongue. This is not normal and could be an indication of a serious health issue. Another thing to look out for is a foul odor coming from your dog’s mouth. There are a lot of possible explanations for this, but it’s better to play it safe and see the vet.

If your dog was not born with any black spots on its tongue, you’ll probably want to take them to the vet just to be safe. While benign black spots can develop in older dogs, it could also be a melanoma. You’ll want to know if this is the case, as waiting longer than necessary to have your dog examined could put its overall health at risk.
