The Greyhound â The King of Canine Racers. When you think of fast dogs, the tall and lean Greyhound is the first breed that usually springs to mind. This long-legged, smooth-coated racing breed has been clocked at speeds up to 45 miles per hour, sparking its nickname: the 45-mph couch potato.
Distance, Conditions and Speed. A sled dog's speed depends on a variety of factors, including weather, the planned travel distance and the condition of the trail. For shorter distances, sled dogs may average 10 to 14 miles per hour during the course of a day of mushing. If conditions are poor, such as extreme cold or fresh snow, the dogs' speed can drop to 6 or 7 miles per hour. In a sprint race that takes a day or two, sled dogs may reach up to 15 miles per hour. The size of the sledding team makes a difference; however, the team will travel only as fast as its slowest member. As well, the amount of weight the team is pulling will affect its overall speed.
