The Alaskan Husky is not so much a breed of dog as it is a type or a category. It falls short of being a breed in that there is no preferred type and no restriction as to ancestry; it is defined only by its purpose, which is that of a highly efficient sled dog. That said, dog drivers usually distinguish between the Alaskan Husky and “hound crosses”, so perhaps there is informal recognition that the Alaskan Husky is expected to display a degree of northern dog type. Specializations in type exist within the breed, such as freighting dogs (Mackenzie River Husky), sprint Alaskans, and distance Alaskans. Most Alaskan Huskies have pointy ears, meaning they are in fact classified as a spitz-type dog.
The Alaskan is the sled dog of choice for world-class dog sled racing sprint competition. None of the purebred northern breeds can match it for sheer racing speed. Demanding speed-racing events such as the Fairbanks, Alaska Open North American Championship and the Anchorage Fur Rendezvous are invariably won by teams of Alaskan huskies, or of Alaskans crossed with hounds or gun dogs. Hounds are valued for their toughness and endurance. Winning speeds often average more than 19 miles per hour (31 km/h) over three days' racing at 20 to 30 miles (32 to 48 km) each day.
Alaskan huskies that fulfill the demanding performance standards of world-class dogsled racing are extremely valuable. A top-level racing lead dog can be worth $10-15,000. Alaskans that fail to meet the performance standards of the musher who bred them often go on to be sold to less competitive mushers, allowing them to continue to run.
