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.
My big dogs have been clocked at about 22 miles per hour over 50 yards or so; the little guy can probably get that fast but needs a stop after about 10 yards. He's all sprint, but doesn't take a lot of time to recover.
