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.
Purposely bred for speed, greyhounds have been clocked at speeds of up to 45 mph. Nevertheless, the website Vetstreet reports that veterinarian Dr. Christine Zink suggests that many other lightweight, fast breeds are nearly as fast as greyhounds are, and reach speeds between 35 and 40 mph.
