My dog has a black birthmark spot on his tongue
Blue-black spots on tongues are very common, much more common than we thought - more than 30 pure breeds are known to have spotted tongues.
Spots on tongues are simply deposits of extra pigment, like birthmarks and freckles on people, some people call them freckles or natural tattoos. Dogs often have spots of dark pigment on their skin, too, you just can see them as they are hiding under their coats. They have all different sizes and could have a lot of them or just one (like Sandy).

Should I take my dog to the vet if I notice bluish-black spots on his tongue?
A bluish tongue color in dogs can indicate a condition called cyanosis - which essentially means there is a shortage of oxygen in the blood. Cyanosis is usually noticeable in the gums and other mucous membranes and can be a symptom of a number of underlying causes, including heart disease, respiratory disease and exposure to a toxin. If your dog's tongue is bluish in color, and this is not normal for him, and you are sure that this is not due to eating anything that could transfer this color (also check toys for transferable dye) then visit a veterinarian for a thorough examination to determine if the discoloration is due to cyanosis.
Remember, it is better to take your dog to the vet and have him say it is nothing than to hope for the best and have something terrible happen. Always err on the side of caution when it comes to your pets.

The original and most famous of breeds for the black tongue is the Chow Chow
The blue-black/purple tongue gene appears to be dominant, as almost all mixed breed dogs that come from a Chow Chow retain the tongue color.

Shar-Pei dogs also have completely black tongues
Shar-Pei dogs also have completely black tongues, but most people know the Shar-Pei from there wrinkles.The Shar Pei, or Chinese Shar-Pei, is a breed of dog known for its distinctive features of deep wrinkles and a blue-black tongue. The breed comes from China. The name translates to "sand skin" and refers to the texture of its short, rough coat. As puppies, Shar Pei have numerous wrinkles, but as they mature, these wrinkles disappear as they "grow into their skin". Shar Pei were in 1978 named as the world's rarest dog breeds by Time magazine and the Guinness Book of World Records, and the American Kennel Club did not recognize the breed until 1991. The Shar-Pei is believed to have shared a common origin with the smooth-coated Chow-Chow because of the blue-black mouths and tongues.
