Greyhound racing is an organized, competitive industry in which greyhound dogs are raced around a track. There are two forms of greyhound racing, track racing (normally around an oval track) and coursing. Track racing uses an artificial lure (now based on a windsock) on a track until the greyhounds cross the finish line. As with horse racing, greyhound races often allow the public to wager on the outcome. In coursing the dogs chase a lure (originally a live rabbit that could be killed by the dog).

In many countries, greyhound racing is purely amateur and for enjoyment. In other countries (particularly Australia, Ireland, Macau, Mexico, Spain, the UK and the US), greyhound racing is part of the gambling industry, similar to although far less profitable than horse racing. There is concern in countries with greyhound gambling regarding the well-being of the dogs and the use of live-baiting. The effectiveness of industry self-regulation is often called into question. A greyhound adoption movement has arisen to assist retired racing dogs in finding homes as pets, with an estimated adoption rate of over 90% in the USA.
