In temperament the breed is quiet and gentle, content to sleep for long stretches, affectionate with its own people and sometimes reserved with strangers. It keeps a strong urge to chase small, fast-moving animals. Many retired racers are rehomed as companions through dedicated charities.
The Greyhound is built for sprinting, with a long, narrow head, small folded ears, a deep chest, an arched loin, a tucked-up waist and powerful hindquarters ending in a long, tapering tail. At full speed it uses a double-suspension gallop, in which the body is airborne both when fully stretched and when fully gathered. The short, fine coat comes in many colours, including black, white, red, blue, fawn, fallow and brindle, alone or broken with white.
The Greyhound's later history in Britain was shaped by organised coursing, in which two hounds were judged on their pursuit of a hare. Its rules are traditionally credited to a Duke of Norfolk in Elizabethan times, and formal coursing clubs appeared in the eighteenth century. The Waterloo Cup, run near Liverpool until hare coursing was outlawed, became its chief fixture. Track racing behind a mechanical lure arrived from the United States in the nineteen-twenties and quickly drew large crowds.
