The Chinook is a rare dog breed of sled dog, developed in the New England region of the United States in the early 20th century. The Chinook is the official state dog of the state of New Hampshire.
Standing in height at the withers and weighing , the Chinook is balanced and muscular. The United Kennel Club (UKC) breed standard states that "The ideal coloration runs from light honey color to reddish-gold. Black markings on the inside corners of the eyes are preferred. Dark tawny to black markings on the ears and muzzle are preferred. Guard hairs on the tail may be black. No white markings are allowed. Buff markings on the cheeks, muzzle, throat, chest, breeches, toes and underside are acceptable." The UKC standard faults any color other than tawny and disqualifies albinism. Other proposed standards state that the medium-length double coat is tawny in color, with darker shadings on muzzle and ears; white dogs are not allowed, nor are other colors. Eyes are brown to amber in color. Ear carriage is variable, but dropped is preferred and the head more strongly rectangular than other sleddog breeds. The tail is a well-furred saber and not the usual brush or plume of Arctic breeds. Overall, the Chinook seems to owe more to molosser than to spitz ancestry.
The breed is described as calm, non-aggressive and very friendly, always kind with strangers and children. They are good with all dogs most of the time.
Health issues include normal hereditary problems such as epilepsy, hip dysplasia, and atopy. Also common is cryptorchidism, which occurs in about 10% of all male dogs.
The Chinook owes its existence to one man: Arthur Treadwell Walden of Wonalancet, New Hampshire. The breed derives principally from one male ancestor born in 1917, named Chinook, who was Walden s lead dog and stud. "Chinook" derived from a crossbreeding of husky stock from the Peary North Pole expedition with a large, tawny Mastiff-like male. Photos of Chinook show a drop-eared dog with a broad Mastiff head and muzzle. Walden s leader was bred to Belgian Sheepdogs, German Shepherd Dogs, Canadian Eskimo Dogs and perhaps other breeds; the progeny were bred back to him to set the desired type and was apparently a strong reproducer of his own traits. Arthur Walden was an experienced dog driver with years of experience in the Yukon; he was the lead driver and trainer on Byrd's 1929 Antarctic expedition. He is credited with bringing sled dog sports to New England and with founding the New England Sled Dog Club in 1924. The 12-year-old Chinook was lost on the Byrd expedition.
Control of the core breeding stock passed from Walden to Julia Lombard and from her to Perry Greene in the late 1940s. Greene, a noted outdoorsman, bred Chinooks in Waldoboro, Maine, for many years until his death in 1963. Rare and closely held by Greene who was for many years the only breeder of Chinooks, the population dwindled rapidly after his death. By 1981 only eleven breedable Chinooks survived. Breeders in Maine, Ohio and California divided the remaining stock and managed to save the type from extinction.
The Chinook obtained registered status with the UKC in 1991; current numbers of registered animals are around 800. Only about 100 puppies are born annually worldwide. The registry has a cross-breeding program under which Chinooks are bred to individuals of other breeds thought to have contributed to Chinook development; fourth-generation backcross descendants of such crosses may be accepted as UKC purebred Chinooks if they meet the Chinook Owner Association's Cross Breeding Program requirements.
Chinooks joined the American Kennel Club (AKC) Foundation Stock Service in 2001 and were later added to the AKC's Miscellaneous Class in 2010. Chinooks are still working for recognition from other major kennel clubs.
Although still used for recreational dog sledding by some owners, Chinooks today appear to be used largely as family pets. Individuals are also used for dog-packing, search and rescue, skijoring, and obedience and dog agility trials.
