Dogs with Black in Their Mouth
Can Your Spot the Spots on this Dog's Tongue?
Whether your dog has black spots on the roof of his mouth, a black tongue or black gums, you may be wondering where those black colors are coming from. You may have heard that dogs with black in the roof of the mouth are much more smarter and easier to train. Some hunters also used to think that dogs with a lot of black on the roof of their mouths made the best hunting dogs, and the more black there was, the better. Some others believe that black spots in a dog's mouth or any black areas in the mouth are suggestive of a dog that is purebred. How true are these statements?
There are several dog breeds across the globe who have black in their mouths, but turns out, a dark mouth isn't necessarily a sign of a purebred dog or of a genius dog with superior cognitive abilities. Nor does it necessarily signal a dog with premium hunting abilities. While it's perfectly normal for some dogs to have black pigment in their mouths, it's important to recognize that in some cases, those black spots may not be normal at all, and they may warrant a vet visit. In the next paragraphs we will take a look at some dog breeds known for having black in their mouths and some causes of black spots in the mouth--and while we're at it, we will also debunk some common myths surrounding those black spots in a dog's mouth, tongue, gums and roof of the mouth.

What Causes Black Spots in a Dog's Mouth?
If you're wondering what causes black spots in a dog's mouth, it's likely the result of heavy pigmentation. These darker spots are the result of microscopic melanin granules and present as flat, pigmented areas found on your dog’s tongue, gums and inside the lips and mouth. As long as these areas are flat and not raised above the surrounding tissues, thy are normal and nothing to worry about, explains Karen Becker, author and veterinarian at Natural Pet Animal Hospital in Bourbonnais, Illinois. For the sake of comparison, consider that those areas of extra pigmentation are sort of like freckles or birthmarks in people. These random spots can be actually found on the tongues of many other breeds. There are actually more than 30 dog breeds known for sporting spotted tongues; however, consider that even mixed breeds can have black spots in their mouths.
However, in some cases, those black area may need veterinary attention. Even if your dog belongs to a breed for which it's normal to have a pigmented mouth, it's good practice to keep an eye out for any abnormalities. Dogs with heavily pigmented skin and mouths have an increased predisposition for developing oral melanoma, explains Robyn Elmslie, a veterinarian specializing in oncology practicing for Veterinary Cancer Specialists in Englewood, Colorado. See your vet if you notice any dark, pigmented areas inside your dog's mouth that look raised instead of flat.
Also, consider that the sudden onset of bluish gums or a purple-tinged tongue in a dog whose gums and tongue are normally pink, warrants an immediate vet visit as this could signal a problem with the heart, circulatory system or some other serious disorder.

Dog Breeds with Blue/Black Tongues
Unlike certain dogs displaying random black spots in their mouths, two dog breeds in particular were specifically bred to have a black tongue and black mouth: the chow chow and the Chinese Shar-Pei. In the American Kennel Club chow chow breed standard, the top surface and edges of the tongue must be solid blue-black, the darker the better. The black tongue feature is so important in this breed that the presence of red or pink spots on the tongue's top surface or edges are considered disqualifying faults.
The American Kennel Club Shar-Pei breed standard instead calls for a preferably solid bluish-black tongue with the roof of the mouth, gums and flews of the same pigment. A solid lavender tongue is only allowed in diluted coats. A spotted pink tongue is considered a major fault, while a solid pink tongue is grounds for disqualification.
Contrary to popular belief, dogs with black spots in their mouth or black tongues don't necessarily have chow chow or Shar-Pei blood running through their veins. These random spots can be found on the tongues of many other breeds or mixed breeds. There are actually more than 30 dog breeds known for sporting spotted tongues and several of them are listed in the table below.

The Myths About Dogs with Black in the Roof of Their Mouths
You may have heard many interesting facts about dogs with black on the roofs of their mouths. Some say that they are smarter, easier to train and make wonderful hunting dogs. Others say that dogs with black in the roof of their mouths instead are more aggressive. How true are all these beliefs? Turns out there's actually no scientific evidence indicating this relationship.
There's belief these old wives tales may have started by some breeder who obtained a batch of pups with black in their mouths who proved to be smarter than the average dog with a pink mouth, and then when these smart dogs were bred, more batches of smart puppies were born and soon the voice spread that dogs with black mouth must have been smarter compared to other dogs. Something similar must have happened with the myths surrounding blondes, red hair and people with freckles.
