The
Greyhound is a
breed of
sighthound that has been primarily bred for
coursing game and
racing, and the breed has also recently seen a resurgence in its popularity as a pedigree show dog and family pet. It is a gentle and intelligent breed. A combination of long, powerful legs, deep chest, flexible spine, and slim build allows it to reach average race speeds in excess of 18 metres per second (59 feet per second) or 63 kilometres per hour (39 mph).
