14 Blue Dog Breeds: Pictures, Facts & History


Blue dogs, like a Blue Heeler or Kerry Blue Terrier, have a dilute black coat or patterns that give them the “blue” name. Some dog breeds come in blue as a standard color, while others may just have a high likelihood of producing blue pups.

Here are the 14 blue dog breeds and the patterns they can come in.


How Are Blue Dog Breeds Classified?

Several dog breeds have a blue color, but it’s not actually blue. It’s more of a silvery gray or ice color, which is known as “blue.” It can be light or a steely shade. Blue dog breeds carry the recessive genes for blue coat coloration from their parents. As long as both parents have the gene for a diluted black coat—which is “blue”—they will produce blue pups.

Some dogs have blue as a known coloration, while others may get a blue coat or patterns outside of the breed standard.

What Is Color Dilution Alopecia?

Color dilution alopecia (CDA) is a genetic recessive inherited condition that causes patches of hair thinning or loss with flaky skin. Typically, color dilution alopecia occurs in dogs with dilute colors, such as blue or fawn dogs. Fortunately, other than appearance and skin issues that need treatment, color dilution alopecia isn’t associated with any other health problems.



Blue dogs come in a variety of breeds. If you have your heart set on a blue dog, there are plenty of options for hunting, sporting, and companion dogs alike. It’s important to consider not only the dog’s looks, however, but their temperament and energy levels to ensure they’re a good fit for your family.
