Greyhound

The Greyhound is a breed of dog and a sighthound. It is an ancient breed historically developed for hunting game by sight and speed, and has later been used in organised coursing and greyhound racing. Greyhounds are also kept as show dogs and companion animals. Greyhounds are characterised by a tall, muscular, smooth-coated build, a long tail, tough feet, and a distinctive flexible, "S-shaped" outline typical of sighthounds. They are a distinct breed from other related sighthounds, such as the Italian Greyhound. The Greyhound's long legs, deep chest, flexible spine, and slim build enable high sprinting speeds. In racing contexts, Greyhounds can reach peak speeds of at least 69 km/h (43 mph), with typical winning speeds of approximately 58–61 km/h (36–38 mph).
