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. Sleds are usually made of light wood, such as ash.
Sled designs are different for each type of race.
Sprint sleds weigh about 30 pounds and are about 5 feet long. The distance sleds are longer, heavier and have a deeper basket. Brakes and snow hooks help keep the sleds still. The sled builders are real craftsmen. Clothing will obviously change with the weather.
