The Alaskan Husky commonly weighs from 20 to 30 kg and stands 60-65 cm high. It has a deep slim chest, long legs and can be one color or multicolors. They are mainly black, grey and white but can also be red or brown. All Alaskan Huskies have heavy undercoats to deal with the low temperatures of their enviornments. The Alaskan Husky is extremly athletic and has very large thigh muscles. They often have a curved sled dog tail and can have blue or brown eyes, or sometimes one of each, like some Siberian Huskies. Usually the ears stand straight up but in a few cases they lay flat. This breed is popular in sled dog racing since it is faster, stronger and has more endurance than the Siberian Husky.
