Dog racing is a competitive sport where dogs, typically breeds like Greyhounds, race around a track. The dogs chase a mechanical lure, often resembling a small animal, which encourages them to run at high speeds. Races are usually held in front of spectators, and the fastest dog wins. The sport has a long history and is popular in various countries, including the United States and Australia. While it can be entertaining, dog racing has faced criticism regarding the treatment and welfare of the animals involved. Many advocates promote the adoption of retired racing dogs to ensure they have a good quality of life after their racing careers.
