The Chinook is a devoted, hardworking American sled dog known for its gentle temperament and steady, willing nature.
How the Chinook coat is built, and what that means when you groom it.
Critical: A Chinook should not be shaved.
The undercoat keeps heat out as well as in, and the outer coat shields the skin from sun and insect bites. Clipping the whole coat off removes both. It often grows back patchy, soft or a different colour, and in some animals the guard hairs never return properly. Brush the undercoat out instead of cutting it off.
Information: A Chinook drops its undercoat in heavy bursts.
The undercoat comes out in heavy bursts over a few weeks. An undercoat rake, or a bath followed by a proper blow-dry, clears it far faster than daily brushing. Clipping the coat down is not a shortcut for this.
A few of the Chinook profiles members have added to United Pet Club.
The Chinook is a medium-sized American sled dog known for a calm, devoted character and a willing, hardworking nature, well suited to Canada's cold climate.
The Chinook is a medium-sized working dog bred in the United States as a sled dog and family companion. Developed in New Hampshire in the early 20th century, it carries a tawny double coat, drop or partly erect ears, and a sturdy, athletic build. Males typically stand roughly 23 to 27 inches at the shoulder and weigh 55 to 90 pounds, with females somewhat smaller.
The breed combines pulling power with a gentle disposition. Chinooks were created to haul loads over long distances, so they have stamina and a steady work ethic, but they were also kept close to their owners and form a strong attachment to people. The temperament is calm, friendly, and people-oriented rather than sharp or aloof.
The Chinook is a natural fit for Canadian conditions. Its dense double coat handles harsh winters across the country well, and the breed's background in sled work makes it a willing partner for outdoor pursuits common here, including hiking, skijoring, and snowshoeing. Canadian families who enjoy year-round activity outdoors will find it a rewarding companion.
A Chinook suits an active household that can give it daily exercise and regular companionship. It is patient with children and generally sociable with other dogs, and it does best when it is part of family life rather than left on its own for long stretches.

The Chinook is a good match for owners who want a steady, affectionate working dog and can commit to daily activity. It rewards consistent training and close contact, and it is less suited to homes that are empty for most of the day or that cannot provide regular outdoor exercise.
The Chinook was developed in New Hampshire in the early 1900s by Arthur Treadwell Walden, bred as an all-purpose sled dog and named after his lead dog.
The Chinook traces to Wonalancet, New Hampshire, where Arthur Treadwell Walden began developing the breed in the early 1900s. Walden was a sled driver and freighter who wanted a dog combining the pulling power of heavier freight dogs with speed and an even temperament. The breed takes its name from one of his lead dogs, Chinook, born in 1917.
Walden built the line by crossing a large tawny dog descended from his foundation stock with other working dogs, then breeding selectively for size, coat colour, and a willing, gentle nature. The resulting dogs were used for sled hauling, freighting, and recreational driving across northern New England.
Chinooks took part in early Antarctic exploration. Dogs from Walden's kennel supported Admiral Richard Byrd's first Antarctic expedition in the late 1920s, and the lead dog Chinook was lost during that journey, an event that became woven into the breed's history.
The breed nearly disappeared in the mid-20th century, with numbers falling very low before a small group of breeders worked to recover it. The Chinook is not yet registered with the Canadian Kennel Club (CKC) as a distinct recognised breed, though American Kennel Club-registered dogs are present in Canada and the breed competes through rare-breed programmes.
The Chinook is a medium, athletic dog with a tawny double coat, a broad head, and ears that may drop, stand erect, or fall somewhere in between.
The Chinook has a balanced, muscular frame built for endurance rather than bulk. The body is slightly longer than it is tall, the chest is deep, and the tail is carried in a gentle curve. The head is broad with a defined stop, and the dark eyes give an alert, friendly expression. Ear carriage varies within the breed: some dogs have drop ears, some stand erect, and many fall between the two, and all forms are accepted.
| Trait | Detail |
|---|---|
| Height | Males 24 to 27 in; females 22 to 25 in |
| Weight | Males 55 to 90 lb; females 50 to 65 lb |
| Coat | Medium double coat, dense undercoat |
| Colours | Tawny, from pale honey to reddish gold |
| Eyes | Brown to amber, almond shaped |
The defining colour is tawny, ranging from light honey to a deeper reddish gold. Darker shading often appears on the muzzle, ears, and the inner corners of the eyes, and small white or buff markings can show on the chest, toes, and underside. The double coat has a coarser outer layer over a soft, insulating undercoat. In Canadian winters this coat is a practical asset, providing genuine protection against cold and wind without needing supplemental gear. The undercoat blows seasonally, requiring extra brushing in spring and autumn.
The Chinook is calm, friendly, and devoted, attaching strongly to its family and getting along well with children and other dogs.
The Chinook is known for a steady, gentle temperament. It forms a close bond with its family and prefers to stay near its people, which makes it affectionate at home but prone to distress if left in isolation for long periods. With children it is patient and tolerant, and with other dogs it is generally sociable, a trait that reflects its history as a team sled dog.
Toward strangers the breed is usually reserved rather than aggressive. Some Chinooks are quietly shy on first meeting and warm up once they have had a chance to assess a new person. Early and regular socialisation helps a shy dog grow into a confident adult.
The Chinook is intelligent and eager to cooperate. It works with its handler rather than against, and it is not strongly vocal, tending to communicate through soft sounds rather than persistent barking. Because it is sensitive, it responds best to calm, consistent handling. The breed's people-oriented nature means it does not thrive when treated as a yard dog or left outside for extended periods, particularly during cold weather, despite the coat's ability to handle the cold.

The Chinook needs daily exercise, weekly brushing that increases during seasonal shedding, and close contact with its family.
The Chinook is a moderate-maintenance breed whose main needs are regular activity, routine coat care, and companionship. It is happiest when it has a job to do and a family alongside.
The Chinook handles Canadian cold well, and owners in colder provinces will find the breed comfortable on winter outings where thin-coated dogs would need protection. That said, it is a companion breed that should live indoors with its family. A home with a yard suits it better than a small urban flat with limited exercise, and it needs regular contact rather than being kept separate from the household.
An active Chinook needs a complete diet matched to its life stage and workload, fed in measured meals to keep it lean.
The Chinook does well on a complete and balanced diet formulated for active medium to large dogs. Because it is a working breed, an individual dog's needs vary with its age, size, and exercise level, so portions should be adjusted to keep the dog at a healthy weight with ribs that can be felt but not seen. Working dogs in heavy training may need considerably more food, while a less active companion needs less to avoid weight gain.
Canadian pet food regulations require products sold here to meet standards set by the Canadian Food Inspection Agency (CFIA), so commercially available complete foods labelled for the appropriate life stage are a reliable starting point. Always check that a product carries an AAFCO or equivalent nutritional adequacy statement.
| Life stage | Amount per day | Meals |
|---|---|---|
| Puppy (2 to 6 months) | Per puppy formula label, by weight | 3 to 4 |
| Junior (6 to 12 months) | About 2.5 to 3.5 cups | 2 to 3 |
| Adult | About 2.5 to 3.5 cups | 2 |
| Working adult | Increase to match workload | 2 to 3 |
| Senior | Adjust down for activity | 2 |
Keep treats to no more than about 10 percent of daily calories and use them primarily for training rewards. Fresh water should always be available. A dog on a complete commercial diet usually does not need supplements; discuss joint support or other additions with a veterinarian, particularly for active or older dogs.
The Chinook is generally healthy with a lifespan of 12 to 15 years, though it can carry hip dysplasia, eye conditions, and a breed-specific seizure-like episode.
The Chinook is a generally sound, long-lived breed, with a typical lifespan of 12 to 15 years. Responsible breeders screen breeding stock for inherited conditions, which has helped keep the small population healthy. As with any breed, knowing the common health concerns helps owners recognise problems early.
In Canada, owners can access veterinary orthopaedic and ophthalmology referral centres in most major cities. Hip screening through programmes such as OFA (Orthopedic Foundation for Animals) and eye certification through CAER are the accepted standards for Chinook breeders in North America, including those working in Canada.
| Condition | Signs | Note |
|---|---|---|
| Hip dysplasia | Stiffness, limping, trouble rising | Screen breeding dogs; keep weight controlled |
| Eye disorders | Cloudiness, vision changes | Routine eye exams recommended |
| Cryptorchidism | Undescended testicle in males | Found on veterinary exam |
| Chinook seizures | Brief episodes of movement difficulty | Breed-specific; often resolves with age |
| Skin or allergy issues | Itching, coat changes | Identify triggers with a vet |
The Chinook is intelligent and eager to please, so it trains readily with patient, reward-based methods and early socialisation.
The Chinook is intelligent, attentive, and willing to work with its handler. It is also sensitive, so harsh corrections tend to backfire and can cause a shy dog to withdraw. Calm, consistent, reward-based training brings out the best in the breed. Because some Chinooks are reserved with strangers, early and ongoing socialisation to new people, places, and other dogs is important for raising a confident adult.
The breed's working background means it genuinely enjoys having a task. Activities such as carting, sledding, agility, and obedience provide a useful outlet, and in Canada the sled sports community offers structured programmes for dogs with pulling drive, from recreational mushing clubs to organised skijoring events held in several provinces.
Chinooks reach breeding maturity at around two years, carry litters for about nine weeks, and produce moderate-sized litters that need careful, well-socialised rearing.
Breeding Chinooks calls for particular care because the breed has a small population and a narrow gene pool, which makes thoughtful pairing and health screening essential. Breeders usually wait until dogs are physically and mentally mature, around two years of age, and confirm clear hip and eye results before mating. Females come into season roughly twice a year.
Gestation lasts about 63 days. Litter size is moderate, and because puppies inherit a sensitive, people-oriented temperament, early handling and socialisation in the first weeks has a lasting effect on how confident the adult dog becomes. Responsible breeders track the breed's limited bloodlines to maintain genetic diversity and reduce the incidence of inherited problems.
In Canada, breeders operating under CKC membership rules are expected to follow the CKC Code of Practice for breeders, which covers health testing and puppy care standards even for breeds not currently listed in the CKC studbook.
| Metric | Value |
|---|---|
| Breeding maturity | About 2 years |
| Heat cycle | Roughly twice a year |
| Gestation | About 63 days |
| Average litter | About 3 to 6 puppies |
| Weaning age | 6 to 8 weeks |
A free lifetime United Pet Club record for your Chinook, with the microchip registered at no cost and kept current through every move.
Canadian shelters and vet clinics scan strays at intake as a matter of routine, and the scan helps only when a registry ties your Chinook to a phone that still rings. Registering your dog with United Pet Club takes a few minutes, never costs anything, and works whether or not a chip is in place yet. Add the breed, a photo, and your postal code, and the record is live.
The vet implants the chip and leaves the recording part to you. Register the microchip on the free lifetime plan: any brand a Canadian clinic implants is accepted, updates after a change of address are free, and a current record keeps the border paperwork the Canadian Food Inspection Agency asks about from becoming a scramble. Create your free account and finish both in one evening.
Open a free United Pet Club account, fill in your Chinook's name, breed details, and a photo, and save. The lifetime plan is free, no chip required, and the chip number can be attached after your vet appointment.
Add the 15-digit number to your account along with your address, postal code, and phone number. Registration and unlimited updates are free for life, and chips from any manufacturer a Canadian vet uses are accepted.
There is no federal requirement, but several cities fold chips into their licensing bylaws, and travel with the dog goes smoother when the chip is registered. The record, not the implant, is what identifies your Chinook.
Nothing, ever. United Pet Club's lifetime plan covers the profile, the chip record, and every update without fees or renewals.
