When Rufus was about six months old – a month after taking him in – I noticed that he had a few new black spots on his tongue. Then a few more and a few more…
The vet said everything was fine so no worries about my dog having a plague.
Some breeds are prone to this. It simply means extra pigment like freckles. And freckles, as we all know, are a sign that the gods sprinkled extra love.
There is a rumor out there that says that a black spotted tongue must mean the dog is part Chow. While the Chow is known for a black tongue (and is required by the AKC to have one for show purposes) there are also another thirty (and change) breeds that have this trait.
Breeds with Black Tongues:
Australian Cattle Dog
Bouvier de Flandres
Kerry Blue Terrier
Soft-Coated Wheaten Terrier
The vet & I are pretty sure he has Boxer, Rottweiler, and Shar Pei in his DNA, and this theory gets extra oomph from this list. Overall, the black tongue, or spotted tongue are fairly common. I only wish that it meant fresher dog breath.
