Bred in Northeast Asia as a sled dog, the Siberian Husky is known for its amazing endurance and willingness to work. Its agreeable and outgoing temperament makes it a great all-around dog, suitable for anything from sledding to therapy work. Because it originated in cold climates, Siberians have a thicker coat then most other breeds of dog, made up of a dense cashmere-like undercoat and a longer, coarse top coat. All colors from black to pure white are allowed, and a variety of markings on the head is common.
