01/Overview
The Kerry Blue Terrier is a medium-sized terrier from Ireland known for its distinctive blue-gray coat, strong build, lively expression, and spirited character. Developed as a versatile farm and hunting dog, the breed combines intelligence, courage, and determination with a loyal and often playful personality.
02/History
The Kerry Blue Terrier originated in Ireland, particularly in County Kerry, where similar blue-coated terriers had been used for generations as all-purpose working dogs. Farmers valued them for their versatility, and the dogs were expected to handle a wide range of jobs rather than perform a single specialized task.
Kerry Blues were used to control rats and other vermin, hunt small game, guard property, and assist with livestock. They were also used for hunting Otters and other quarry, requiring strength, persistence, and the ability to work in difficult terrain.
The breed’s exact ancestry is not fully documented. It likely developed from native Irish terriers, with possible influence from other working dogs found in the region. Over time, selective breeding produced the characteristic soft, wavy coat and blue-gray coloring that distinguish the breed today.
Kerry Blue Terrier puppies are born black, with the coat gradually changing color as the dog matures. This progressive clearing process can take many months and is one of the breed’s most recognizable characteristics.
The breed became more prominent during the early twentieth century as Irish fanciers worked to establish a consistent type and promote it at organized dog shows. The Kerry Blue Terrier quickly became closely associated with Irish national identity and was one of the native breeds shown during the early development of organized canine competition in Ireland.
The Irish Kennel Club was founded in 1922, and the Kerry Blue Terrier played an important role in its early history. The breed was already gaining recognition beyond Ireland during this period and soon attracted interest in Britain and the United States.
The American Kennel Club recognized the Kerry Blue Terrier in 1922 and placed it in the Terrier Group. The United States Kerry Blue Terrier Club serves as the breed’s American Kennel Club parent club.
The Royal Kennel Club also recognizes the Kerry Blue Terrier in the Terrier Group. The Fédération Cynologique Internationale recognizes it as an Irish breed and places it in Group 3, Terriers, Section 1, Large and Medium-Sized Terriers.
03/Appearance
An adult male Kerry Blue Terrier stands 18 to 19.5 inches tall at the withers, while a mature female stands 17.5 to 19 inches tall. Males typically weigh 33 to 40 pounds, with females weighing somewhat less.
Skull: The Kerry Blue Terrier has a long, well-proportioned head with a flat skull and only a slight stop. The head should appear strong without becoming coarse or overly broad.
Expression: The expression is keen, alert, and intelligent, reflecting the breed’s confident and spirited character.
Eyes: The eyes are small, dark, and well placed, contributing to a sharp and attentive expression.
Ears: The ears are small to medium in size, V-shaped, and carried forward close to the cheeks. They are set high on the skull and should not appear heavy or overly large.
Muzzle: The muzzle is strong, deep, and well filled beneath the eyes, with powerful jaws and a clean outline.
Nose: The nose is black with large, open nostrils.
Bite: The Kerry Blue Terrier has strong white teeth that meet in a level or scissors bite, where the upper incisors slightly overlap the lower incisors.
The Kerry Blue Terrier is compact, well balanced, and strongly built, with a body that is close to square in proportion. The overall outline should convey strength, agility, and athletic ability without appearing heavy or coarse.
The chest is deep and moderately broad, with well-sprung ribs, a short back, and a strong loin. Bone is substantial in proportion to the dog’s size, providing the strength expected of a versatile working terrier while preserving freedom and efficiency of movement.
Texture: The Kerry Blue Terrier has a soft, dense, wavy coat without a harsh or wiry texture. The coat should be abundant and have a natural wave, giving the breed its distinctive appearance while remaining close enough to preserve the outline of the body.

Health
The Kerry Blue Terrier is generally considered a healthy and sturdy breed with a typical lifespan of 12 to 15 years. Preventive veterinary care, balanced nutrition, regular exercise, good dental hygiene, and maintenance of a healthy weight can help support long-term health.
The Kerry Blue Terrier is confident, intelligent, energetic, and deeply loyal to its family. It often has a strong personality and may be both playful and independent, especially when it decides that something else is more interesting than the task at hand.
The breed can be affectionate with familiar people but may be reserved or assertive around unfamiliar dogs. Early socialization is important, and careful introductions can help the Kerry Blue develop appropriate behavior around other animals and new situations.
Kerry Blue Terriers can live successfully with respectful children, particularly when raised with them. Their strength and enthusiastic play style may be better suited to families with older children.
Exercise Expectations
A healthy adult generally benefits from about 60 minutes of activity each day, although particularly energetic individuals may need more. Scent games, retrieving, puzzle toys, and dog sports can provide additional mental engagement. Because the breed may have a strong prey drive and can be assertive around other dogs, off-leash exercise should take place only in a securely enclosed area.
Grooming Expectations
The Kerry Blue Terrier can often adapt to apartment living when given enough exercise, training, and mental activity. Its energy level, alert nature, and strong personality may require additional management in smaller homes.
A securely fenced yard can provide space for play, but outdoor time should not replace walks, training, and interaction with the family. The breed generally prefers living indoors and remaining involved in daily household life.
The Kerry Blue Terrier usually does best in a household that appreciates its intelligence, confidence, and independent character. Regular companionship, consistent routines, and structured activity help the breed thrive.
05/Puppies
Kerry Blue Terrier puppies are lively, curious, and quick to learn. Early routines, positive socialization, patient training, and regular grooming will help any pup develop into a confident and well-mannered adult.
A Kerry Blue Terrier puppy benefits from a predictable daily schedule that includes regular meals, potty breaks, sleep, play, training, and quiet time. A crate or secure puppy area can provide a safe place to rest and support housetraining when direct supervision is not possible.
Early socialization should introduce the puppy to different people, well-mannered dogs, household sounds, surfaces, vehicles, and unfamiliar environments. These experiences should remain positive and appropriate for the puppy’s age.
Training can begin as soon as the puppy arrives home. Short sessions can introduce name response, recall, leash walking, basic manners, impulse control, and calm greetings. Because the breed can be confident and independent, consistent expectations are especially important from an early age.
A Kerry Blue Terrier puppy should receive a complete and balanced diet formulated for growth. Exercise should focus on supervised play, short walks, and gentle exploration rather than forced running or repetitive jumping while the puppy is still developing.
Regular veterinary visits are important during the first year. Grooming should also begin early so that the puppy becomes comfortable with brushing, combing, beard care, nail trimming, ear checks, tooth brushing, and general handling.

Official Standard of the Kerry Blue Terrier
General Appearance: The typical Kerry Blue Terrier should be upstanding well knit and in good balance, showing a well-developed and muscular body with definite terrier style and character throughout. Correct coat and color are important. A low-slung Kerry is not typical.
Size, Proportion, Substance: The ideal Kerry should be 18½ inches at the withers for a dog, slightly less for a bitch. In judging Kerries, a height of 18 to 19½ inches for a dog, and 17½ to 19 inches for a bitch, should be given primary preference. Only where the comparative superiority of a specimen outside of the ranges noted clearly justifies it should greater latitude be taken. In no case should it extend to a dog over 20 inches or under 17½ inches, or to a bitch over 19½ inches or under 17 inches. The minimum limits do not apply to puppies. The most desirable weight for a fully developed dog is from 33 to 40 pounds, bitches weighing proportionately less. A well-developed and muscular body. Legs moderately long with plenty of bone and muscle.
Head: Long, but not exaggerated, and in good proportion to the rest of the body. Well balanced. Eyes -Dark, small, not prominent, well placed and with a keen terrier expression. Anything approaching a yellow eye is very undesirable. Ears - V-shaped, small but not out of proportion to the size of the dog, of moderate thickness, carried forward close to the cheeks with the top of the folded ear slightly above the level of the skull. A "dead" ear, houndlike in appearance, is very undesirable. Skull - Flat, with very slight stop, of moderate breadth between the ears, and narrowing very slightly to the eyes. Foreface full and well made up, not falling away appreciably below the eyes but moderately chiseled out to relieve the foreface from wedginess. Little apparent difference between the length of the skull and foreface. Jaws deep, strong and muscular. Cheeks-Clean and level, free from bumpiness. Nose - Black, nostrils large and wide. Teeth - Strong, white and either level or with the upper (incisors) teeth slightly overlapping the lower teeth. An undershot mouth should be strictly penalized.
Neck, Topline, Body: Neck - Clean and moderately long, gradually widening to the shoulders upon which it should be well set and carried proudly. Back short, strong and straight (i.e., level), with no appearance of slackness. Chest deep and of moderate breadth. Ribs fairly well sprung, deep rather than round. A slight tuck-up. Loin short and powerful. Tail should be set on high, of moderate length and carried gaily erect, the straighter the tail the better.
Forequarters: Shoulders fine, long and sloping, well laid back and well knit. The elbows hanging perpendicularly to the body and working clear of the side in movement. The forelegs should be straight from both front and side view. The pasterns short, straight and hardly noticeable. Feet should be strong, compact, fairly round and moderately small, with good depth of pad free from cracks, the toes arched, turned neither in nor out, with black toenails.
Hindquarters: Strong and muscular with full freedom of action, free from droop or crouch, the thighs long and powerful, stifles well bent and turned neither in nor out, hocks near the ground and, when viewed from behind, upright and parallel with each other, the dog standing well up on them.
Coat: Correct coat is important it is to be soft, dense and wavy. A harsh, wire or bristle coat should be severely penalized. In show trim the body should be well covered but tidy, with the head (except for the whiskers) and the ears and cheeks clear.
Color: Color is important. The correct mature color is any shade of blue gray or gray blue from the deep slate to light blue gray, of a fairly uniform color throughout except that distinctly darker to black parts may appear on the muzzle, head, ears, tail and feet. Kerry color, in its process of "clearing," changes from an apparent black at birth to the mature gray blue or blue gray. The color passes through one or more transitions-involving a very dark blue (darker than deep slate), shades or tinges of brown, and mixtures of these, together with a progressive infiltration of the correct mature color. The time needed for this "clearing" process varies with each dog. Small white markings are permissible. Black on the muzzle, head, ears, tail and feet is permissible at any age. A black dog 18 months of age or older is never permissible in the show ring and is to be disqualified. Disqualification - A black dog 18 months of age or older is to be disqualified. (White markings on a black dog 18 months of age or older does not constitute clearing or mature color and the dog is to be disqualified.)
Gait: Full freedom of action. The elbows hanging perpendicularly to the body and working clear of the sides in movement; both forelegs and hind legs should move straight forward when traveling, the stifles turning neither in nor out.
Disqualifications: A black dog 18 months of age or older is to be disqualified. (White markings on a black dog 18 months of age or older does not constitute clearing or mature color and the dog is to be disqualified.)

The correct mature color is any shade of blue gray or gray blue, from the deep slate to light blue gray, and of a fairly uniform color throughout except that distinctly darker to black parts may appear on the muzzle, head, ears, tail and feet. Kerries appear black when born, and the color changes to the mature gray blue or blue gray. The color passes through one or more transitions. The time needed for this "clearing" process varies with each dog. A black dog 18 months of age or older is to be disqualified from competing in the show ring.

A Kerry Blue Terrier should receive a complete and balanced diet suited to the dog’s age, activity level, and body condition. Portions should be measured carefully because excess weight can reduce agility and place unnecessary strain on the joints.
A puppy generally needs three or four small meals each day before gradually moving to two meals. Most adults are fed twice daily, with the amount adjusted according to the food’s caloric density and the dog’s level of activity.
Treats can be useful during training but should be given sparringly. Fresh water should always be available.
The Kerry Blue Terrier is intelligent and capable of learning quickly, but it can also be independent and strong-willed. Training is most effective when sessions are short, varied, and supported by praise, food rewards, toys, or play.
Early socialization should introduce the puppy to different people, well-mannered dogs, environments, sounds, and surfaces. Recall, leash manners, impulse control, and calm greetings are especially important because the breed can be strong and energetic.
Clear and consistent expectations can help to prevent unwanted habits such as pulling, excessive barking, or ignoring commands. Patient, reward-based training usually produces the best results.
The coat is typically trimmed and shaped regularly to maintain the breed’s characteristic outline. Unlike many terriers, the Kerry Blue is not hand-stripped because its coat is soft rather than harsh and wiry. The beard should be cleaned regularly because it can collect food and moisture. Nails should be trimmed as needed, ears should be checked for irritation or debris, and teeth should be brushed routinely.
