Take your dog to the vet. It may be sick. On the other hand, you may just have a breed that naturally has a purple tongue. I know there is some kind of breed that does.

i think thats like chow or sharpe my dog has it to she is mixed basengii and sharpe.well if it wasnt born that way take it to the vet

It means that your dog is probably part chow.

do you by any chance have a chow dog? they have purple tounges and sometimes black spots on their gums.

Dog!!!!!!!!!!!!!!!!!!?

What breed is it? Could be part chow. Chows are known for their purple tongue.

could just be from the breed, or it could be something else, call your vet for a quick look.

It may just be a birthmark. My grammas dog had chow, and chow have those weird colorings on their tongues

shows and Sharpais have purple tongues so more than likely your dog has one of these mixes.
