A husky is a sled dog used in the polar regions. One can differentiate huskies from other dog types by their fast pulling-style. When used as a sled dog, they represent an ever-changing crossbreed of the fastest dogs. Humans use huskies in sled-dog racing. Various companies have marketed tourist treks with dog sledges for adventure travelers in snow regions. Huskies are also kept as pets, and groups work to find new pet homes for retired racing and adventure-trekking dogs.
