Additional information (Wiki): The greyhound is a breed of hunting dog that has been primarily bred for coursing game and racing, but with a recent resurgence of popularity increasingly as a pedigree show dog and family pet. It is a soft and intelligent breed that often becomes attached to its owners. It is the fastest breed of dog. A combination of long, powerful legs, deep chest, flexible spine and slim build allows it to reach speeds of around 70 kilometres per hour (43 mph).

Although greyhounds are extremely fast and athletic, and despite their reputation as racing dogs, they are not high-energy dogs. They are sprinters, and although they love running, they do not require extensive exercise. Most are quiet, gentle animals. An adult greyhound will stay healthy and happy with a daily walk of as little as 20 to 30 minutes. Greyhounds have been referred to as "Forty-five mile per hour couch potatoes."

Until the early twentieth century, greyhounds were principally bred and trained for coursing. During the early 1920s, modern Greyhound racing was introduced into the United States and introduced into The United Kingdom (Belle Vue) in 1936 and Northern Ireland (Celtic Park) on April 18, 1927 and immediately followed by Shelbourne Park in Dublin very soon after.[citation needed] The greyhound holds the record for fastest recorded dog.
