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.
A sled dog's typical racing pace averages between 10 to12 miles per hour (16 to19km/h), which means that every 6 hour running period he covers about 70 miles (112 km). These dogs keep this up for an average of 11 days! It is hard to imagine any other animal on land that could keep up that kind of pace.
