The Siberian Husky was originally bred as a sled dog and this animal has incredible endurance. These pups have a thicker coat than many other breeds, with a soft fluffy undercoat and a dense, coarse top coat. With this thick coat, Huskies thrive in sub-zero temperatures, allowing them to make long treks through the winter snow. The Siberian Husky loves to run and is an active breed that often has a happy-go-lucky temperament. Huskies are long famous for participating in the grueling long-distance Iditarod race.
