Size and Build
The Kerry Blue Terrier is a robust, medium-sized terrier with males typically standing 22-24 inches tall and weighing 64-75 pounds. Females are slightly smaller, standing 20-22 inches and weighing 55-64 pounds. Their body is well-proportioned, with a deep chest, well-sprung ribs, and a flat back. The neck is strong, leading smoothly into flat shoulders. Their legs are straight and strong, with small rounded feet and black nails. The hindquarters are muscular, supporting an agile and free-moving gait.
Coat and Colors
Their hallmark coat is soft, dense, and wavy, reminiscent of astrakhan fur rather than typical terrier hair. Puppies are born with black fur, which gradually shifts to the characteristic slate-blue color by around 18 months. Recognized colors by The Kennel Club include black, black and blue, black turning blue, and solid blue. A small white patch on the chest is allowed in conformation showing and is not penalized.
Distinctive Features
Kerry Blues possess a distinctive long, flat-topped head with a slight stop, a strong muzzle with powerful jaws, and a black nose. Their eyes are dark and medium-sized, reflecting a keen, alert terrier expression. Ears are V-shaped, moderately small, and carried forward. The tail is moderately long, set high, thick at the base tapering to the tip, and usually held straight but carried gaily when excited. Their movement is energetic, free, straight, and parallel in both front and hind limbs without twisting of the stifles.
Gender Differences
Males tend to be slightly taller and heavier with a more dominant demeanor. Females are typically lighter and display a somewhat more reserved nature but share the breed’s characteristic alertness and energy. Both genders require consistent grooming and active management.
Breed Standard and Show Ring Preferences
The breed standard highlights a balanced, athletic build without exaggerations that could impair health or working ability. Judges look for the typical slate blue coloring, strong scissor bite, and confident, lively movement. Docking of tails was traditional but is now illegal except for approved working dogs or medical reasons, so natural tails are the norm in modern shows.
