Smaller than the similar-appearing Alaskan Malamute, the Siberian Husky pulls more, pound for pound, than a Malamute. Descendants of the sled dogs bred and used by the native Chukchi people of Siberia which were imported to Alaska in the early 1900s, they were used as working dogs and racing sled dogs in Nome, Alaska throughout the 1910s, often dominating the All-Alaska Sweepstakes. They later became widely bred by recreational mushers and show-dog fanciers in the U.S. and Canada as the Siberian Husky, after the popularity garnered from the 1925 serum run to Nome. Siberians stand 20–23.5 inches, weigh between 35 and 60lbs (35-50 for females, 45-60 for males), and have been selectively bred for both appearance and pulling ability. They are still used regularly today as sled dogs by competitive, recreational, and tour-guide mushers.
