Kerry Blue Terrier Traits

General Appearance

Famous for its spectacular blue coat, this former farm breed is a smart-looking, comfortably-sized dog.

Coat and Colouring

The Kerry Blue Terrier's wiry coat is various shades of blue (gray). The color ranges from pale silver to deep slate. Kerry Blue puppies are born black and get lighter as they age—a process called clearing. These dogs may also have darker shading on their feet, heads, and tails.

Distinctive Physical Traits

The striking blue coat is a signature feature of this muscular breed. The Kerry Blue also sports a stylish beard, small V-shaped ears that fold forward, and dark eyes that complement its long head.

Kerry Blue Terrier Temperament

Kerry Blue Terriers are intelligent. But like many terriers, they have an independent streak. Though these dogs are known to be strong-headed and highly spirited, they're also loving and affectionate toward their families and very gentle with children.

Common behaviors to be aware of are chasing wildlife, barking, and digging. Because of their working dog backgrounds, Kerry Blue Terriers can be challenging to distract once they're engaged in an activity.

Kerry Blue Terrier History

Developed in County Kerry, the Kerry Blue Terrier is the national dog of Ireland. Its exact origins are a mystery, but legends abound.

According to one story, when only the Irish nobility was permitted to hunt with the Irish Wolfhound, peasants developed the Kerry Blue Terrier so they could poach. Some experts speculate that the Kerry was created by breeding the Irish Wolfhound with a basic terrier breed (an Irish Terrier or English Terrier).

Another tale proposes that Kerry Blue Terriers are the offspring of a Russian Blue Dog that swam ashore when a Russian ship wrecked in Tralee Bay in southwest Ireland. The Russian Blue Dog purportedly bred with local terriers to produce the Kerry Blue. A similar tale theorizes that the shipwreck was part of the Spanish Armada.

Though the true story of the breed's origins remains a mystery, one fact is indisputable: When it comes to faithfulness and friendliness, these dogs are legendary.

The Kerry Blue first appeared in a dog show in 1916. And the American Kennel Club recognized the breed in 1924.

Kerry Blue Terrier Care


The Kerry Blue Terrier requires a high-quality dog food that is appropriate for its age and activity level. It's important to monitor the amount of food you feed your Kerry Blue and reduce the portions if your pup gains weight. Also, remember that giving too many treats in addition to regular meals can contribute to obesity.


Kerry Blue Terriers don't shed. But they still need to be brushed thoroughly every week. And combing their coats is essential to keep them from matting. When it's time for a trim, use clippers to cut the hair on the head, neck, ears, and belly and a pair of scissors for the coat.


Active, spirited dogs, Kerry Blue Terriers like swimming and jogging. Exercise them enough outdoors, though, and they'll welcome calm family time inside the home. This breed also enjoys agility, earthdog trials, flyball, herding, hiking, retrieving, tracking, Frisbee, musical freestyle, rally, and competitive obedience.


Kerry Blue Terriers can be stubborn. But that doesn't mean training is impossible—it just may be a bit more challenging. Kerry Blues respond well to reward-based training approaches. For example, offer their favorite treat as a reward for dropping an inappropriate item (such as your shoe) that they've retrieved.

Like all breeds do, Kerry Blue Terriers benefit from socialization and obedience training early on in life.

Kerry Blue Terrier Genetic Health Conditions

  • Factor XI Deficiency

    Factor XI Deficiency is a hereditary disorder that impacts blood clotting. The disease usually causes a mild, spontaneous bleeding disorder but more severe bleeding may occur following surgery. Many dogs that are at risk will not show any signs of disease.

  • von Willebrand's Disease, type 1

    von Willebrand's Disease (vWD) type 1 is a clotting disorder that usually causes mild bleeding tendencies in affected dogs though some may have more severe signs. The low level of von Willebrand's factor impacts the bloods clotting ability.
