15 Bold and Beautiful Blue Dog Breeds


A blue dog is not truly blue, but more of a silvery-gray or icy color. Blue-coated dogs have noses that appear to have a bluish shine to them, and many have blue eyes that emphasize their blue coat sheen. The blue color can vary from light, pale blue, or a deeper, steely shade of blue.

Blue dogs come in all sizes. Some breeds are known for their blue coat, while others carry the blue coat gene outside the breed standard. Many blue dog breeds are sought after and highly prized for their good looks and unique blue coat markings, including blue tick, blue merle, blue harlequin, blue brindle.

Breed Characteristics

Blue dog breeds carry the recessive genes for blue coat coloration from their parents. Both parent dogs do not have to be blue, but each will have the gene for a diluted black coat. If your dog has the merle gene, it can manifest as mottled patches of color. Merle-pattered dogs cannot consistently create pigment, which explains the bluish coloration. Blue merle dogs also have a greater chance of having blue eyes or heterochromia—two different colored eyes.

Color dilution alopecia is an inherited hair loss that affects dogs that have a dilute fur color, such as blue or fawn. Also known as color mutant alopecia, this inherited disease is a result of a recessive gene that causes brittle hair growth before progressing to an inability to grow new hair completely.

Here are the top 15 breeds known for carrying the blue coat gene.

    Also known as the blue heeler, it’s no surprise that the Australian cattle dog lands on the list of best blue dog breeds. While a red coat is also possible (known as the red heeler), a blue coat on this dog may be solid, mottled, or speckled according to the breed standard. Other markings in black or tan may be present, but the overall impression of a blue heeler is a blue cast.

    Kerry Blue Terrier

    As the name suggests, the Kerry blue terrier only comes in one color: blue. This breed has a unique, curly coat that ranges in shade from a deep slate to a light blue-gray. While the muzzle, head, ears, tail, and feet may be darker (or even black), the breed standard calls for a dog that is described as either “blue-gray” or “gray-blue,” with either color showing more dominantly. However, the blue hue should not be missing. All Kerry blue puppies are born black. Through a process called “clearing,” the coat of a Kerry blue terrier gradually changes to the characteristic blue coat color by about 18 months.

Breeds to Avoid

If blue dogs meet your fancy, then pure white dogs, devoid of any color, would likely not interest you. The snowy coats of Arctic dogs like the Samoyed and American Eskimo dog adapted to match their frozen surroundings, while white dogs like the Komondor, with its long, white corded coat, blended in with the sheep it would herd. Other popular white breeds include the Great Pyrenees, West Highland terriers, and bichon frise.
