Sled dog

Sled dogs were important for transportation in arctic areas, hauling supplies in areas that were inaccessible by other methods. They were used with varying success in the explorations of both poles, as well as during the Alaskan gold rush. Sled dog teams delivered mail to rural communities in Alaska and northern Canada. Sled dogs today are still used by some rural communities, especially in areas of Alaska and Canada and throughout Greenland. They are used for recreational purposes, and are raced in events known as dog sled races such as the Iditarod and the Yukon Quest.

Sled dogs probably evolved in Mongolia between 35,000 and 30,000 years ago. Scientists believe that humans migrated north of the Arctic Circle with their dogs, and using them to pull sleds 3,000 years ago, when communities were forced north to Siberia by pastoralists. Sled dogs have been used in Canada, Lapland, Greenland, Siberia, Chukotka, Norway, Finland, and Alaska.

Historical references of the dogs and dog harnesses that were used by Native American cultures date back to before European contact. The use of dogs as draft animals was widespread in North America. There were two main kinds of sled dogs; one kind is kept by coastal cultures, and the other kind is kept by interior cultures such as the Athabascan Indians. These interior dogs formed the basis of the Alaskan Husky. Russian traders following the Yukon River inland in the mid-1800s acquired sled dogs from the interior villages along the river. The dogs of this area were reputed to be stronger and better at hauling heavy loads than the native Russian sled dogs.
