The Iditarod Sled Dog Race is the major race for the distance runners. Dog mushing is a fun winter sport. Sled dogs , which were often wolf breeds, were used by Eskimo and Indian mushers for transportation and a means of survival. Before WWI supplies, medicine, and mail were hauled over the historic Iditarod Trail. This Alaskan tradition has changed over the years.
Many serious mushers spend years and lots of money to breed dogs.
Size will vary, as well as coat and stamina. Husky or the native word Huski is the common sled dog. Malamute is a name for a dog breed native to the Yukon. Siberian Husky has been a tough breed. They are rather large, so they usually don't run the sprint races.
