Dog Racing, contest in which trained greyhounds compete against one another by pursuing a swiftly moving, mechanical lure around a circular or oval track. The sport is internationally popular, especially in the United Kingdom, the United States, Australia, Ireland, Spain, and Mexico. Dog racing is an outgrowth of coursing, a sport involving the pursuit of live game by sight rather than scent.
Greyhound Race: While chasing an electrically propelled lure in racetracks built specifically for dog racing, greyhounds may reach speeds of up to 64 km/h (40 mph). The breedís physical attributes, such as its deep chest and great lung capacity, narrow and aerodynamic head, and strong muscles, give the greyhound its rapid acceleration and speed.
