Hare coursing is the pursuit of hares with greyhounds and other sighthounds, which chase the hare by sight and not by scent. It is a competitive sport, in which dogs are tested on their ability to run, overtake and turn a hare, rather than a form of hunting aiming at the capture of game. It has a number of variations in its rules around the world. Informal coursing can be a true form of hunting. It is often conducted to kill game or vermin, mainly for food, and occasionally as a form of gambling.
Coursing is a long established hunting technique, practiced historically with greyhounds, other sighthound breeds, or with lurchers which are crossbred sighthounds, and working breeds. The sport grew in popularity in Europe during the 19th century, but has since experienced a decline due in part to the introduction of greyhound racing and betting.
