About the Kerry Blue Terrier
The Kerry Blue Terrier is a compact, strong, medium-sized dog and one of the larger terriers. Its profuse, soft, silky and wavy coat comes in shades of blue-grey. Despite its glamorous looks it keeps a feisty terrier spirit, and is often described as intelligent, charming and trustworthy, but also fierce.

The breed takes its name from its place of origin, County Kerry in south-west Ireland, and from the colour of its coat. It was a versatile farm dog, used to kill rats, guard property and even hunt otters in rivers. Its origins are disputed, but records describe a black or blue type of dog native to Kerry that may have been the basis for the breed. It is now the National Dog of Ireland.
The breed was first shown in Ireland in 1913 as the Irish Terrier (Blue), and the name Kerry Blue Terrier was first used at a show in Killarney in 1916. The Royal Kennel Club recognised it in 1922. Today the Kerry Blue is more popular as a show dog than a working dog, and the Royal Kennel Club lists it as a vulnerable native breed.
Kerry Blue Terrier temperament
Kerry Blues are typically spirited, clever and independent. Bred to deal with vermin and guard property, they are still formidable characters, and if left untrained they may make their own decisions in ways that lead owners into trouble.
They are natural guards and are vocal, and may be protective or suspicious of visitors. A quieter home or a more rural setting usually suits them better than a busy town household, where constant stimulation can leave them loud and stressed.
Size and appearance
The Kerry Blue is a medium-sized breed. Adults typically stand around 46–48 cm at the shoulder and weigh around 15–17 kg.
Puppies are born black and gradually change to shades of blue by around 18 months of age. Breed standard colours are black, black and blue, black turning blue, and blue.
How much exercise does a Kerry Blue Terrier need?
An hour a day of walking and free running is the bare minimum for a Kerry Blue, and ideally they get much more, including training that engages their sharp brains.
Activities that recreate hunting work well, as does scent-based work such as tracking and man-trailing.
Training a Kerry Blue Terrier
Kerry Blues respond well to positive reinforcement and are quick learners once they believe what you want was their idea in the first place. They need an experienced owner who can offer calm, consistent and kind training.
- Start socialisation early with other dogs, children and livestock.
- Use positive, reward-based methods and keep their minds busy.
- Stay aware of their game, feisty nature: they rarely ignore a challenge or a perceived threat.
- Make sure fencing is secure, as they can jump over, dig under or squeeze through weak spots.
Kerry Blue Terrier grooming
The soft, silky, wavy coat does not shed. It needs regular brushing, with daily brushing recommended by some sources, and a clip every six to eight weeks.
Check the coat after walks, paying particular attention to paws and ears, as the soft coat can collect debris.
Living with a Kerry Blue Terrier
Because of their independent nature and strong desire to hunt, Kerry Blues are usually better suited to families without children or with older teenagers. They are unlikely to tolerate toddlers or the noise of babies well, which can lead to a stressed, unhappy dog. Older teenagers with an interest in dog training may enjoy the challenge.
Whatever the breed, dogs and young children should never be left alone together, and an adult should supervise every interaction.

Often better suited to an adult home.

Can be selective about other dogs.

Flats and smaller homes

Garden

Kerry Blue Terrier health
Not yet reviewed by a vet. This is general information, not veterinary advice: speak to your vet about your own dog’s health.
The Kerry Blue Terrier is generally a hardy breed, with no widely recognised breed-specific health problems.
Genetic diversity
The breed's numbers in the UK are low, and the Royal Kennel Club lists prioritising genetic diversity as a key part of responsible breeding. Ask breeders about the health history of the parents.
What health checks should you ask about?
Responsible breeders and rescues are happy to talk about health, and any pressure to decide quickly is a reason to walk away. Before taking a Kerry Blue Terrier home, it is reasonable to ask about:
- Health testing of the parents. Ask which health tests the parents have had for conditions known in the breed, and to see the results.
- Veterinary and vaccination records. Puppies should have had a first vaccination and a vet check, with records you can take home.
- Microchip information. In England, Scotland and Wales puppies must be microchipped and registered by eight weeks old. Ask who the chip is registered to and how the transfer works.
- Registration paperwork. Registration papers, where they apply, record pedigree. They do not by themselves prove health or how a puppy was raised.
How much does a Kerry Blue Terrier cost to own?
There are two costs: bringing a Kerry Blue Terrier home, and looking after one well. Puppy prices depend on the breeder, health testing and demand; the adverts below show what sellers are asking today.
Ongoing costs are the ones new owners most often underestimate: food, insurance (which usually rises with age), routine vet care, vaccinations and parasite treatment, dental care, grooming, training, bedding and equipment, and boarding or a sitter for holidays. Budget for the whole of the dog’s life, typically from 10 years, not just the first year.
Buying a Kerry Blue Terrier
If you have decided the Kerry Blue Terrier suits your life, take the same care choosing where your dog comes from. Meet the puppy in person, see it with its mother, and look at how the litter is raised.
- Check who you are dealing with: every Mypetzilla advert shows the seller type and what we have checked.
- Ask about health testing, vaccinations and the microchip before you commit.
- Take your time. Do not be rushed by deposits or "last one left" stories.
- Meet in person before paying anything, and keep conversations on Mypetzilla.
Adopting a Kerry Blue Terrier
Kerry Blue Terriers do come up for adoption, through rescue organisations, breed rescues and private rehoming, often because an owner’s circumstances have changed rather than any fault of the dog. An adult dog arrives as a known quantity: its size, coat and character are already on show.
Rescues will usually talk you through the dog’s history, any medical care, and the home it needs, including children, other animals and time alone. Be honest about your circumstances: a good rescue would rather place a dog once, well.
