Hare coursing is the pursuit of hares with greyhounds and other sighthounds, which chase the hare by sight, not by scent.
In some countries, it is a legal, competitive activity 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. Coursing can also be a form of hunting or pest control. It is a long-established hunting technique, practiced historically in England, especially with greyhounds or sighthound breeds, or with lurchers which are crossbred sighthounds. 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 with betting, and laws passed that have banned the practice.
In recent decades, controversy has developed around hare coursing, with some viewing it as a cruel bloodsport. Hare coursing is illegal in the United Kingdom. In other countries, including Spain, Ireland and the Western United States, it is a regulated and judged, competitive sport.
