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.
At a speed of 14 to 18 miles per hour, Labrador retrievers provide excitement when playing and running alongside a companion. Other dogs can hit much higher speeds than the Labrador retriever. The fastest dogs are greyhounds.
