History of the Kerry Blue Terrier Breed
The history of the Kerry Blue Terrier is a blend of mystery and classic Irish legends. The breed’s homeland is considered to be the mountainous County Kerry in southwestern Ireland, where these dogs have been cherished for centuries as versatile farmhands. Local lore has it that blue terriers have lived in these lands forever, although the first written records only date back to 1847.
One of the most romantic legends tells of a wondrous blue dog that swam to the shores of Ireland from a shipwrecked vessel. It is said to have been the ancestor of the modern Kerry, who, after reaching the land, defeated all the local terriers and became the founding sire of a new, exceptional breed. Another, more plausible version, links their origin to the Irish Soft Coated Wheaten Terrier, which was possibly crossbred with other breeds to improve its working qualities.
Originally, Kerry Blue Terriers were the dogs of commoners. They were used for a wide range of tasks:
- Hunting: They were excellent at hunting badgers, foxes, otters, and other small game.
- Herding: They helped herd sheep and cattle.
- Guarding: They were reliable protectors for farms and homes.
- Retrieving: They would retrieve downed game from the water.
True recognition came to the breed in the early 20th century, when Irish patriots, including Michael Collins, chose the Kerry Blue Terrier as a symbol of the struggle for Irish independence. In 1920, the first breed club was formed in Dublin, and by 1922, the breed made its debut at the prestigious Crufts show in England. Their elegant appearance and exceptional character quickly won the hearts of dog lovers across Europe. At one of the 1928 shows, the Kerry Blue Terrier was even called “the almost perfect dog”.
What the Kerry Blue Terrier Looks Like: A Description of its Appearance

The Kerry Blue Terrier is a well-built, sturdy, and elegant medium-sized dog. Its look combines the power of a terrier with grace. The dog’s silhouette is square, which speaks to its well-proportioned body.
The breed’s main feature is its coat. It’s soft, silky, dense, and wavy, with no undercoat. This structure makes Kerries hypoallergenic because they hardly shed. Interestingly, puppies are born completely black, and only by 18-24 months does their coat gradually change, acquiring its final blue shade. This shade can range from a light silver-blue to a dark steel-blue. Thanks to this unique soft coat, the Kerry stands out from most terriers, for example, from the Wire Fox Terrier with its wiry coat, or from the sheep-like Bedlington Terrier.
| Body Part | Description according to FCI Standard No. 3 |
|---|---|
| Head | Long, proportional, with a dense coat. The skull is strong and well-balanced. The stop is barely noticeable. |
| Muzzle | Jaws are strong and muscular. Scissor bite. Nose is black, nostrils are large. |
| Eyes | Dark, from medium to dark brown, of medium size, with an alert “terrier” expression. |
| Ears | Thin, small, V-shaped, lying close to the cheeks, pointing forward. |
| Neck | Proportional, muscular, elegantly set on the shoulders. |
| Body | The back is straight, short, and the topline is level. The chest is deep and moderately wide. |
| Tail | Thin, set high, the dog carries it vertically and cheerfully. It used to be docked. |
| Limbs | Straight, parallel, with a strong bone structure. Paws are compact, pads are firm, claws are black. |
Temperament and Behavior
Kerry Blue Terriers are dogs with big hearts and a vibrant temperament. They are very loyal and bond deeply with their family, becoming true companions. With their loved ones, they are affectionate, playful, and friendly dogs who love being the center of attention. They are very patient with children and are ready to be part of all family activities, whether it’s a hike in the mountains or a quiet evening on the couch.
However, like all terriers, Kerries have a flip side. They can be stubborn and independent. Their hunting instinct and courage sometimes lead to conflicts with other dogs, especially if a Kerry feels challenged. They won’t look for a fight, but they will never back down from one. Therefore, early and consistent socialization is absolutely necessary for this breed. From a young age, a puppy needs to be introduced to different people, animals, sounds, and situations.
Kerries are reserved and suspicious of strangers, which makes them excellent watchdogs. They will always warn you with a loud bark when guests are approaching. They need an owner with a firm but fair character who can be a leader for the dog. Despite their stubbornness, Kerries are very smart and eager to please their owner, which makes them quick learners with the right training approach.
Pros and Cons of the Kerry Blue Terrier Breed
Before getting such an energetic and smart dog, it’s worth weighing all the pros and cons.

Kerry Blue Terrier Health: Typical Diseases and Prevention

Kerry Blue Terriers are generally a healthy and resilient breed with a lifespan of 12-15 years. However, like many purebred dogs, they have a predisposition to certain genetic diseases. Responsible breeders test their dogs for hereditary conditions, so it’s important to study the pedigree of a future puppy.
The most common health problems in the breed include:
- Hip and Elbow Dysplasia: Improper joint development that can lead to arthritis and lameness. It’s important not to over-exert a puppy with physical activity during its growth period.
- Eye Problems: The most common are entropion (inward-rolling of the eyelids) and dry eye syndrome (keratoconjunctivitis sicca). Entropion is corrected surgically. Cataracts are also possible in old age.
- Skin Diseases: Due to their dense coat, Kerries are prone to skin cysts and tumors. Any growths on the skin require a vet’s attention.
- Chronic Otitis: Ear inflammation. Due to their floppy ears and dense hair in the ear canal, ventilation is poor, which creates favorable conditions for infections.
- Cerebellar Abiotrophy (PNA): A rare but fatal neurological disease that appears in puppies at 2-4 months of age. There are DNA tests to identify carriers.
Prevention involves regular vet check-ups, proper nutrition, sufficient physical activity, and careful grooming of the coat, ears, and eyes.
How to Groom a Kerry Blue Terrier’s Coat
Grooming is the most crucial aspect of owning a Kerry Blue Terrier. Their luxurious coat requires constant attention, or it will quickly mat and lose its attractive appearance. Irish Blue Terriers will feel great even in a small apartment, provided they get enough exercise. Regular walks and outdoor games are absolutely essential for them.
- Daily Brushing: The coat should be brushed with a metal comb and a brush daily or at least 3-4 times a week to prevent the formation of tangles, especially in the areas of the beard, paws, and underarms.
- Professional Trimming: Every 6-8 weeks, a Kerry needs professional grooming. Show dogs are trimmed to a specific standard that accentuates their elegant physique. Pet owners can opt for a simpler, hygienic trim.
- Beard Care: After each meal, the beard must be washed and dried to avoid an unpleasant odor and bacterial growth.
- Ear and Eye Care: Regularly inspect and clean the ears, removing excess hair from the ear canal. Wipe the eyes daily with a cotton pad moistened with a special lotion.
- Claws: Trim the claws every 3-4 weeks if they don’t wear down naturally.
Training and Socialization

You need to train a Kerry Blue Terrier consistently and persistently from the very first day it comes home. These are very smart dogs who quickly grasp new information, but their innate stubbornness requires patience and leadership skills from the owner. Training should be based on positive reinforcement—praise, treats, and games. Harshness and physical punishment will only make the situation worse and can make the dog withdrawn or aggressive.
The “Come!” command is very important, as impulsive Kerries might chase a cat or another dog, ignoring the danger. Keep training sessions short but regular so the dog doesn’t get tired or lose interest. Their high intelligence and energy make Kerries perfect candidates for various dog sports like agility, obedience, or flyball. This is a great way to channel their energy in the right direction, similar to how other energetic dogs are trained, for example, the Dunker Norwegian Hound, although the methods for terriers and hounds, of course, differ.
Socialization is the key to successful training. From puppyhood, get the dog used to different people, animals, sounds, and places. This will help raise a balanced and confident dog that won’t show aggression toward others. Remember that a Kerry is not a dog that will blindly follow commands. It will always first consider whether it’s worth doing. Your job is to become an authority figure for them that they will trust.
Kerry Blue Terrier Nutrition: Key Recommendations
Proper nutrition is the foundation of your pet’s health and longevity. For a Kerry Blue Terrier, both high-quality premium or super-premium dry food and a natural diet are suitable. The main thing is a balanced diet.
Feeding a puppy:
- Up to 2 months: 5 times a day.
- 2-4 months: 4 times a day.
- 4-10 months: 3 times a day.
- After 10 months: 2 times a day (morning and evening).
For a natural diet, the basis of the ration (about 70%) should be lean meat (beef, turkey, chicken) and offal. You should also include in the menu:
- Sea fish without bones (1-2 times a week).
- Grains (buckwheat, rice).
- Fermented milk products (cottage cheese, kefir).
- Vegetables and fruits (carrots, pumpkin, apples).
- Eggs (1-2 times a week).
It is strictly forbidden to give a Kerry: fatty meat, smoked products, sweets, pastries, tubular bones, legumes, and food with spices. It is important not to overfeed the dog, as Kerries are prone to gaining excess weight, which negatively affects their joints and heart. The dog should always have access to clean drinking water.
