Examine the color of your pit bull's nose. A blue pit bull will have a charcoal gray or blue-gray nose, or a combination of those colors and small bits of pink. If your dog has a brown, black or red nose, you probably do not have a blue pit bull.
Look at the color of your dog's fur. A blue pit bull's coat will primarily be the characteristic blue-gray or charcoal gray color, possibly with white patches. If your dog has dark black, red, brindle, tan or brown fur, it's probably not a blue pit bull.
Examine the color of your pit bull's eyes. If your dog has blue, gray or light amber colored eyes in combination with the blue coat and nose, it is likely a blue pit bull. Some blue pits have darker eyes, but lighter colors are more common.
How to Tell You Have a Blue Pit Bull
The American pit bull terrier comes in several color variations, including the popular blue pit bull. These dogs are actually a diluted black color that only appears blue to the human eye. Some pit bull breeders try to profit from the blue pit's color, calling these dogs rare and charging high prices for them, but they are no different from other pit bulls, aside from color. If you are looking to satisfy your own curiosity, there are certain characteristics you can look for to determine if your dog is a blue pit bull.
