Mackenzie River husky describes several overlapping historical populations of Arctic and sub-Arctic sled dog originally bred to support fur traders for Hudson’s Bay Company and later prospectors during the Klondike Gold Rush. A mixture of native sled dogs and European freighting dogs, Mackenzie River huskies were prized for their ability to haul heavy loads long distances in the snow with minimal care. Since the advent of modern mechanized travel in the Arctic, moving cargo by dogsled has become nearly obsolete and only small populations of these dogs still exist. The Mackenzie River husky stands 26 to 29 inches (66 to 74 cm) in height and weighs 63 to 104 pounds (29 to 47 kg). Usually long-coated, they are rangy, deep-chested and long-legged, built for heavy freighting in single file through deep snow. Their colors are the usual northern-dog range of black and white, shades of grey and sable, tan, blond, and red. (Source: Wikipedia.org, CC BY-SA)
