Chinook
The State Dog of New Hampshire — bred by Arthur Walden in 1917 for polar expeditions, once so rare it made the Guinness Book as the rarest breed on Earth.
Overview
The Chinook is a rare American sled dog, created in New Hampshire in the early twentieth century for a mix of freight hauling, sled work, and family life. Adults stand 22 to 26 inches at the shoulder and weigh 55 to 90 pounds. The breed carries the classic sled dog build without the extreme features of the racing Husky or the massive frame of the Malamute. Tawny coloring and dark facial markings give the Chinook a warm, wolfy look that's unmistakable.
In temperament the breed is gentle, calm, and famously friendly. Chinooks were bred as family sled dogs, and the dual role shows. They pull hard on the trail and settle quietly at home. The breed is one of the rarest AKC-recognized breeds in the country, with only a few hundred living Chinooks worldwide. Owners typically come to the breed through the dedicated preservation community that saved it from extinction in the 1980s.
History & origin
The breed's founder was Arthur Treadwell Walden, a New England writer and adventurer who ran a farm in Wonalancet, New Hampshire. In 1917, Walden bred a large tawny male puppy called Chinook, whose sire was a Northern husky-type dog and whose dam was descended from Admiral Peary's lead sled dog. This puppy became the breed's foundational stud and the source of its name.
Walden used Chinook and his descendants for freight hauling, tourist rides, and Antarctic exploration. In 1929, he was chief dog driver on the Byrd Antarctic Expedition, and Chinook himself accompanied the trip at age twelve before disappearing on the ice, presumed lost. Walden continued breeding until his death in 1947. Perry Greene took over the breed and kept it alive for another few decades from his Maine kennel.
By the 1960s Chinook numbers had crashed to fewer than 30 living dogs. In 1981, only 11 breedable Chinooks remained worldwide. A determined preservation effort by breeders in the northeastern United States rebuilt the population using careful outcrossing and inbreeding management. The AKC admitted the breed to full recognition in 2013. Numbers remain small but stable, and the breed is the state dog of New Hampshire.
Appearance
The Chinook is a medium-large sled dog with a balanced, muscular build. Males stand 24 to 26 inches and weigh 70 to 90 pounds. Females run 22 to 24 inches and 55 to 70 pounds. The head is broad, wedge-shaped, with a moderate stop and a well-defined muzzle. Eyes are medium-sized, almond-shaped, and range from dark brown to light amber. Ears are typically dropped or slightly folded, though standing ears also appear and are acceptable.
The coat is a proper double coat built for cold weather work. The outer coat is medium in length, straight, and lies close to the body. The undercoat is thick, soft, and insulating. Color is always some shade of tawny, from pale honey to deep reddish gold, with darker markings on the muzzle, ears, and around the eyes preferred. White is minimal and allowed only on chest, belly, and toes. The tail is well-furred, carried down at rest and in a gentle curve when moving. Movement is smooth, tireless, and built for distance rather than speed.
Temperament
Chinooks are calm, patient, and affectionate. They're deeply people-oriented and thrive on family involvement. With strangers they're polite and friendly rather than reserved or effusive. The breed lacks the guardian temperament of many working dogs and doesn't typically alert-bark or challenge visitors. It's a working sled dog with a companion dog's social side.
Same-sex dog aggression is uncommon. Chinooks were bred to work in teams and generally get along well with other dogs. Prey drive exists but is moderate rather than extreme, and many Chinooks live peaceably with cats and small pets when raised alongside them. The breed's willingness to work with people rather than against them is its defining feature and reflects Walden's careful selection for both function and temperament.
Living with one
The Chinook adapts to a range of homes but thrives with active families in rural or suburban settings with space to run. Rural properties, farms, and homes with large yards suit best. Suburban homes work well with committed daily exercise. Apartments are possible for well-exercised adults but not ideal because the breed's size and activity needs push against city constraints.
Climate tolerance runs strongly cold. The double coat handles winter beautifully, and Chinooks love snow, cold, and sled or scootering work. Hot climates require adaptation. The breed pants heavily in heat and needs air conditioning and dawn or dusk exercise timing during warm months. It's still adaptable to warm regions if owners commit to managing heat exposure.
Alone-time tolerance is moderate to poor. Chinooks bond intensely and prefer their family close. Extended isolation produces anxiety and quiet destructive behavior. The breed does best in homes where someone is around most of the day or where daycare or dog-walking arrangements bridge working hours. Two Chinooks handle absence better than one.
Noise level is low. Chinooks rarely bark and generally aren't vocal. They may howl occasionally, especially with other dogs, but casual barking isn't part of the breed's makeup. Neighbors are unlikely to complain about a Chinook's sound level.
Training & exercise
Chinooks are smart, willing, and quick to learn. They respond beautifully to positive methods and don't tolerate harsh corrections well. Sessions should be short, upbeat, and reward-based. The breed excels at sled sports, weight pulling, obedience, agility, and rally, and it does particularly well in activities that combine physical work with handler partnership.
Socialization from puppyhood matters but comes easier than in more reserved breeds. Chinooks are naturally friendly, and positive puppy exposure produces confident, sociable adults. Puppy classes and structured outings help develop the friendly temperament the breed is known for.
Common mistakes include under-exercising the breed (Chinooks were bred to work all day and need real physical outlets) and expecting the aloofness of some Northern breeds (Chinooks are warmer and more people-focused). What works is regular structured exercise, patient positive training, and access to sled sports, hiking, or similar activities that honor the working heritage.
Grooming & care
The double coat sheds moderately most of the year and heavily twice a year during seasonal blowouts. Weekly brushing with a slicker and undercoat rake keeps things manageable, and daily brushing during the two annual coat drops helps clear the loose undercoat efficiently. Baths every two to three months are typically enough.
Nails need trimming every three to four weeks in non-working dogs. Check ears weekly. Dental care matters. Brush teeth several times a week. The double coat should never be shaved. Shaving damages the insulation properties and can result in a coat that grows back poorly.
Health & lifespan
Lifespan is 12 to 15 years, respectable for a medium-large working breed. The breed's small population and careful preservation breeding have kept the gene pool functional but also concentrated some inherited issues. Responsible breeders test extensively.
Hip dysplasia is a concern in the breed, and both parents should carry OFA or equivalent hip certifications. Elbow dysplasia occurs at moderate rates. Cryptorchidism, where one or both testicles fail to descend, appears in some lines and is a heritable condition to track. Epilepsy occurs in some family lines and is difficult to predict.
Other conditions of note include eye issues (cataracts, progressive retinal atrophy) and skin allergies. Cancer rates are typical for medium-large dogs. The breed's small population means health issues can spread quickly if not managed carefully, and reputable breeders track pedigrees closely to avoid concentrating problems.
Screenings responsible breeders provide include hips, elbows, eyes, and often cardiac and thyroid panels. The Chinook Owners Association maintains a health database that helps track hereditary issues across the small population. Ask for full pedigree health history rather than just individual clearances.
With kids & pets
Chinooks raised with children in the family are wonderful. The breed's gentle, patient nature, moderate size, and low reactivity make it well-suited to family life with kids of all ages. Chinooks tolerate rough handling better than many breeds and rarely react defensively to being climbed on or grabbed. Best in homes ready to include the dog in family activities rather than isolate it in a yard or crate.
First-time owner note
A reasonable choice for a committed first-time owner willing to work with the breed's rarity and the preservation community. Chinooks are friendly and trainable, but their exercise needs and rare status mean owners should expect long waiting lists and mentor-breeder relationships. Not appropriate for owners looking for a common, low-maintenance family dog.
