Kerry Blue Terrier Dog Breed Information

The Kerry Blue Terrier is the national terrier of Ireland and one of the rarest terriers in NZ. Adults stand 44 to 49 cm at the shoulder, weigh 15 to 18 kg, and carry a soft single coat that arrives black on the puppy and clears to slate blue by age three. The breed sits between the Wheaten and the Irish Terrier on the Irish-terrier spectrum: low-shedding like the Wheaten, dog-selective like the Irish Terrier, and more biddable than either when training is consistent.

The point to know up front is that this is not a low-grooming breed. The single coat that sheds almost nothing onto the couch is the same coat that needs scissoring every four to six weeks to keep the breed-typical silhouette and prevent matting. Owners who want a low-shedding terrier without a four-weekly groom usually end up with a clipped pet trim that loses the breed look but cuts the workload roughly in half.

Personality and behaviour

Kerry Blues are confident, affectionate and unmistakably terrier. The breed is more demonstrably loving with its family than the Irish Terrier, more reserved with strangers than the Wheaten, and more dog-selective than either. Most adults are good with school-age children, polite with familiar visitors, and watchful at the gate without becoming reactive at every passer-by.

The trait that surprises new owners is the dog-on-dog selectivity. The Kerry Blue is one of the breeds historically used for dog-fighting in 19th-century Ireland and the breed has not entirely shed the underlying drive. A Kerry Blue puppy raised at the dog park looks fine until 12 to 18 months, when adolescence sharpens the breed’s natural opinion about unfamiliar same-sex dogs. By two years many Kerry Blues prefer single-dog life or one-and-done households with one opposite-sex companion they have grown up alongside.

The other surprise is the colour change. Most owners know puppies are born black, but the timeline of clearing surprises people. A Kerry Blue at six months can still look mostly black; the slate-blue colour does not finish setting until two to three years. NZ buyers picking a puppy for the colour need patience.

Care and exercise

Plan on 70 minutes of real exercise per day, including off-lead time. The breed wants a job. The Kerry Blue does well at obedience, agility, scent work, tracking and beginner gundog work. Daily on-lead walks through the suburbs are not enough; the dog needs structured outlets to settle.

The grooming workload is the breed’s headline cost. The single soft coat does not shed onto the couch but mats fast and needs scissoring rather than stripping. Practical routine for an NZ Kerry Blue:

• Brush three to four times a week down to the skin, especially around the head, beard, armpits and rear.
• Professional groom every four to six weeks, NZ$110 to NZ$180 per visit, depending on the city and trim style.
• Breed-correct presentation (the stylised Kerry Blue silhouette with sculpted head furnishings) takes longer and costs more than a simple all-over pet trim.
• Wipe the beard daily; the long facial furnishings collect food and water and develop a smell if not maintained.

A summer trim (15 to 25 mm all over) is standard practice for NZ owners north of Taupo. The single coat traps heat in upper North Island summers, and a shorter coat through January and February makes a real difference.

The breed is generally healthy. Hereditary cataracts and progressive neuronal abiotrophy (a neurological condition) used to be more common but breed-club screening has reduced the incidence; reputable NZKC breeders eye-test annually and DNA test for known hereditary disorders. Hip scoring under the Dogs NZ scheme is standard.

Training a Kerry Blue Terrier in New Zealand

Kerry Blues are smart and willing for terriers, with a long history of working trial and obedience success. The breed responds well to reward-based methods and short, varied sessions. Long repetitive obedience drills bore the breed quickly.

Recall and dog-on-dog management are the lifelong projects. The breed’s same-sex reactivity is genuine, and recall built only at the local park collapses when an unfamiliar same-sex dog appears. Build recall on a long line through adolescence, maintain controlled positive exposures with calm adult dogs through the second year, and don’t trust off-lead distance in busy areas until the dog has shown reliability across a range of contexts.

NZKC obedience clubs and SPCA puppy classes handle the breed well. Expect NZ$120 to NZ$280 for a six-week course.

Where to find a Kerry Blue Terrier in New Zealand

The breed is genuinely rare in NZ.

1. Registered NZKC breeders. The Dogs NZ breed directory lists active Kerry Blue breeders. Active NZ breeders number one or two at any given time, litter sizes run 4 to 7 puppies, and waitlists of 12 to 24 months are normal. Expect NZ$2,500 to NZ$4,200 per puppy. Reputable breeders provide hip scores, annual eye certificates, and DNA tests for known breed disorders, plus early socialisation in the breeder’s home.
2. Australian breeders. Some NZ buyers source from registered Australian Kerry Blue breeders and import. Total cost (puppy plus quarantine plus flights) typically NZ$5,500 to NZ$8,000.
3. Rescue. Kerry Blues turn up rarely in NZ rescue. SPCA centres see one or two surrendered adults a year at most. Adoption typically NZ$400 to NZ$700.

Avoid Trade Me listings without parent health screening, and avoid sellers who can’t show the dam in person. The breed’s hereditary screening (eye certificates, hip scores, DNA tests) is the most important question to ask any breeder.

Insurance and lifetime cost

Kerry Blue insurance claims in NZ skew toward skin disease, eye conditions, hip and joint issues and senior cancer. Lifetime cover handles the chronic conditions and the senior years that accident-only policies do not.

For a typical NZ Kerry Blue on a mid-range lifetime policy, lifetime cost (purchase, setup, plus 12 to 15 years of food, vet, grooming, insurance and other) lands around NZ$32,000 to NZ$45,000. Grooming alone runs NZ$8,000 to NZ$15,000 across the dog’s lifetime if a professional groom every four to six weeks is maintained.

What surprises new Kerry Blue owners

Three things come up repeatedly with NZ Kerry Blue households.

The grooming time is real. The single coat that sheds almost nothing onto the couch needs four-weekly professional scissoring to keep the breed-typical look. Owners who skip the schedule end up with a matted dog that has to be clipped down at the next groom.

The dog-on-dog selectivity is genuine, especially same-sex. Multi-dog households with two males or two females of any breed can run into trouble in the second year. Single-dog or one-and-done opposite-sex pairings work best.

The colour change takes years. A Kerry Blue puppy can still look black at 12 months, and the breed-typical slate-blue colour is not fixed until two to three years. Patience is part of buying the breed.
