Sled dogs, known also as sleigh man dogs, sledge dogs, or sleddogs, are highly trained types of dogs that are used to pull a dog sled, a wheel-less vehicle on runners also called a sled or sleigh, over snow or ice, by means of harnesses and lines.
Sled dogs have become a popular winter recreation and sport in North America and Europe; sled dogs are now found even in such unlikely places as Germany and Japan. Several distinct dog breeds are used as sled dogs, however, dog drivers have a long history of using other breeds or crossbreeds as sled dogs. There are two main qualities that are expected in sled dogs: endurance and speed. Racing sled dogs will travel up to an average 20 mph (32 km/h) over distances up to 25 mi (40 km).
