Description of a Chinook.

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 lead driver and trainer on the 1929 Byrd antarctic expedition. He is credited with bringing sleddog sport 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 Mrs. Julia Lombard and from her to Perry Greene in the late 1930s. 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 United Kennel Club 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 purebred Chinooks if they meet the Chinook Owner Association\'s CrossBreeding Program requirements.
