The grey hound racing was introduced in the United States by the inventor of artificial hare, O.P. Smith. This led to the formation of the American â??International Greyhound Racing Association (I.G.R.A), which formalized the racing of grey hounds in America. Progress started in the form of frequent races etc in the early 1920s throughout America.
The United States regulates Grey hound racing through state laws, so different states and the government associated see the racing in different perspectives enabling a complete ban in some states while allowing the racing organizations to govern themselves with no interventions from the government in other states.

The greyhounds generally live in kennels, built up of indoor crates stacked two levels high with the upper compartment allocated to the female greyhounds while the lower compartment is allocated to the male greyhounds. Each country has a separate measurement regarding the space allocated to the greyhounds. In United States, the crate size is 1.2 meters deep and 0.9 meters high. While in the track during the racing season, the greyhounds spend most of the time in their â??kennelsâ??.

The dogs were treated like professional racers since all the bets were solely dependent on them and their performance. So they lived in climate controlled surroundings which suited them and eradicated any physical fatigue. They also were made to stay on or near the race tracks to exclude unnecessary travel to and forth the race track. But however, they were taken for walks, mild exercises and playing to ensure that they are physically fit.
