By Tailwisp Editorial TeamUpdated October 17, 20263 min read

The Kerry Blue Terrier is a tall, bearded terrier with a soft blue-gray coat and a confident, take-charge attitude. It was developed in County Kerry, Ireland, as an all-round farm dog and is known as one of the most versatile terriers.

Origins and appearance

The breed worked in Ireland as a farm and herding dog and a vermin hunter, and was used to retrieve game. It became a national symbol and Ireland's unofficial national dog. Kerry Blues are square, with a long head, a strong beard, small folded ears and a soft, wavy coat that is born black and turns blue-gray over the first two years. The tail is traditionally carried upright.

Temperament

Kerry Blues are bold, intelligent and loyal. They are devoted to family, often affectionate and playful, but they can be dominant and protective. Many are dog-selective, particularly as they mature. They need strong leadership, early socialization and plenty of exercise. They are alert watchdogs.

Exercise

They need an hour or more of daily activity, including walks, play and training. They enjoy agility, herding, tracking and obedience. A secure fence and a leash outdoors are important. See recall training guide.

Training

They are very intelligent and quick, but strong-willed. Use consistent, fair and positive training. Early and continuing socialization with dogs and people is essential. House training is usually straightforward.

Coat and grooming

The coat needs brushing several times a week and professional trimming every six weeks. See curly coat dog grooming guide. The beard should be cleaned after meals. Trim nails, check ears and brush teeth. Shedding is minimal.

Health considerations

Topics include:

• Cerebellar abiotrophy, an inherited neurological disease with a DNA test
• Hip dysplasia. See hip dysplasia in dogs
• Skin problems and allergies. See dog skin allergies
• Eye conditions, including cataracts
• Hereditary factor XI deficiency, a bleeding disorder
• Cancer and ear infections

Living with a Kerry Blue Terrier

They suit active owners with fenced yards. They need company and dislike being alone for long hours. Supervise around small pets.

Behavior and daily management

A Kerry Blue needs structure. Provide exercise, training and tasks, and teach a settle cue. Manage introductions to other dogs and reward calm behavior. Keep fences secure.

Puppies and the first year

Puppies are black and bouncy. Socialize extensively, begin grooming practice and train early. See puppy socialization checklist.

Costs and commitment

Plan for professional grooming, training and vet care. See dog vet cost guide.

Seasons and travel

Kerry Blues tolerate cold and damp weather, but need shade in heat. They travel well when introduced early.

Common mistakes

Common mistakes include skipping socialization, underexercising, neglecting grooming and allowing dominance with other dogs.

Questions to ask a breeder or rescue

Ask about DNA tests for cerebellar abiotrophy and factor XI deficiency, hip scores and the parents' temperaments.

Is it the right breed for you?

A Kerry Blue suits experienced, active owners who want a bold, versatile, low-shedding terrier. It may not suit first-time owners or homes with multiple dogs. For a softer-coated cousin, see the Soft Coated Wheaten Terrier.

Training notes

Kerry Blues are quick and have strong opinions. Use fair, firm and consistent training with rewards for good choices. Practice calm behavior around other dogs from the start, and avoid putting an adult in situations where it may feel forced to defend itself. Many do well in obedience, tracking and herding classes.

What the breed is like indoors

Indoors, a Kerry Blue is a watchful, affectionate family dog that likes to supervise the household. Expect barking at unusual sounds and a talent for finding the warmest spot in the house.

The takeaway

Kerry Blues are bold, bearded and blue, and they need socialization, exercise and professional grooming.
