What happens at a greyhound race is this, dogs run on an oval track chasing a lure until the cross the finish line. The first dog to that line wins. The lure resembles a rabbit. These dog begin their training at 8 weeks of age and once 6 month old their training will become more thorough with their career ending at the age of 5 or 6 years.
This is a popular sport and seen all over the world with more than 50 racing tracks in the U.S. alone. Weekly, there are thousands of greyhound events taking place in not only America but Ireland, Australia and the United Kingdom also. Online you can search the greyhound data base for addition information. It is called the World Greyhound Directory.
Many times these dogs run on the same tracks that race horses use. Racetracks are built in a way as to host not just one type of race and so they have multiple uses. Although dog and horse tracks are either oval or circular in shape, cars, motorcycles and even human racing are sometimes done on these tracks as well. Betting can be done on any dog you choose as a win, place or show category.
