Chinook
奇努克犬
Updated 2026-09-09
At a glance
The Chinook is a tawny, no-frills sled dog founded in Wonalancet, New Hampshire, by the musher Arthur Walden as a dual-purpose hauler with the power of a freighting dog and the speed of a racer; once on the verge of extinction, it remains one of the scarcest AKC breeds and is not recognised by the CKC, The Royal Kennel Club or the FCI. Devoted, smart and patient, it is calm and people-oriented with a special feel for children, easy to train with positive methods and — unusually for a sledding breed — can be reliable off leash; its friendly, confident nature means no training will make a guard dog of it. Mellow indoors, it has tremendous energy for hiking, biking, sledding and skijoring with its family.

Health
This page is general information compiled from published sources. It is not veterinary, legal or purchase advice. Dogs vary within a breed — talk to a vet or a reputable breeder about the dog in front of you.
Health notes are not veterinary advice. Conditions listed are those reported for the breed, not a diagnosis of any dog. Always consult a veterinarian.
Hip dysplasia
Commonly reported in the breed; breeders screen hips by X-ray. Ask your vet about hip screening and about keeping your dog lean and fit.
Inherited eye conditions
Various inherited eye conditions are reported in the breed; annual eye examinations by a veterinary ophthalmologist are recommended for breeding stock. Ask your vet about eye screening.
Patellar luxation
Patellar luxation (slipping kneecaps) is commonly reported in small breeds; breeders screen for it. Ask your vet if your dog skips or holds up a hind leg.
Skin and allergy problems
Skin problems and allergies are commonly reported in the breed. Ask your vet if you notice itching, redness or recurring ear/skin infections.
"Chinook seizures" (movement disorder)
Some Chinooks have episodes known as "Chinook seizures", which the AKC says are generally thought to be a movement disorder rather than true seizures. Ask your vet promptly if your dog has an episode, and tell your breeder.
MDR1 drug sensitivity
The parent club's AKC-approved 2022 health statement names the MDR1 mutation (sensitivity to certain drugs) among the disorders identified in the breed; a DNA test is available. Tell your vet before any medication is given.
Skeletal dysplasia / dwarfism
Chondrodysplasia is listed in the parent club's health statement, and a 2025–26 University of Pennsylvania study found the chondrodystrophy (CDDY) mutation in about 26% of modern Chinooks, associated with reduced stature but, on the club's survey data, a low risk of premature disc disease. Ask your breeder about CDDY testing.
Behaviour
Reliable off leash, hopeless as a guard dog
The AKC says Chinooks are easy to train with positive reinforcement and, unlike most sledding breeds, can be reliable off leash; young ones are enthusiastic and affectionate and tend to jump up face-to-face with people unless taught early not to, and because of their friendly, confident, outgoing personality no amount of training will make a guard dog out of one. Socialisation and puppy classes are recommended as for all breeds.
Mellow at home, energy to burn outdoors
The AKC describes calm, people-oriented dogs with a special feel for children that often look relaxed around the house yet have tremendous energy and thrive on exercise and play; because they bond strongly with their owners they make great companions for long walks, hikes, bike rides, camping, swimming and boating, and naturally excel at sledding, skijoring, bikejoring and scootering. The parent club adds that Chinooks can be sweet and laid back but thrive with some type of job, and love playing with children.
Training and barking
AKC trait chart: trainability 4/5, barking level 5/5. Individual dogs vary; early socialisation and reward-based training are recommended for every breed.

What owners say
Owner advice is quoted from public community posts and reflects those owners' opinions, not PocketPaw's position. It is unverified and not a substitute for professional advice. Each item links to where it was said.
“The parent club's health page reports the first study of the chondrodystrophy (CDDY) mutation in Chinooks, by University of Pennsylvania researchers in 2025–26: the mutation has been in the breed for at least 20 years, about 26% of today's Chinooks carry it, it is associated with reduced stature, and on the club's disc-disease survey carriers have a low risk of premature IVDD — the mutation does not reliably predict early-onset disc disease in young dogs. The club's 2022 health statement names hip dysplasia, eye issues, the MDR1 mutation and chondrodysplasia as the breed's identified disorders and encourages all owners to take part in health testing and research.”
