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.
Several strains of dogs have been bred for extreme speed. The fastest of all seems to be the saluki of Arabia, or the related Afghan hound, which can step out at 43 mph and overtake the fastest Arabian horse. Greyhounds and whippets sometimes reach 35 or 40 mph in dog races.. 17.88 m/s.
