The Siberian Husky (Russian: Сибирский хаски, tr. Sibirskiy khaski) is a medium-sized working dog breed. The breed belongs to the Spitz genetic family. It is recognizable by its thickly furred double coat, erect triangular ears, and distinctive markings, and is smaller than a very similar-looking dog, the Alaskan Malamute. Siberian Huskies originated in Northeast Asia where they are bred by the Chukchi people for sled-pulling, guarding, and companionship. It is an active, energetic, resilient breed, whose ancestors lived in the extremely cold and harsh environment of the Siberian Arctic. William Goosak, a Russian fur trader, introduced them to Nome, Alaska during the Nome Gold Rush, initially as sled dogs.
