Greyhound racing is a competitive sport where specially bred dogs, known as greyhounds, race around a track. The dogs chase a mechanical lure, often resembling a small animal, which is designed to encourage them to run at high speeds. Races typically last about 30 seconds, and the fastest dog wins. This sport has a long history, originating in the 19th century, and has gained popularity in various countries. While it can be entertaining, greyhound racing has faced criticism regarding the treatment and welfare of the dogs involved, leading to ongoing discussions about ethical practices in the industry.
