Greyhound racing is a competitive sport where trained dogs, specifically Greyhounds, race around a track. The dogs chase a mechanical lure, often resembling a small animal, which is designed to stimulate their natural instincts. Races typically last around 30 seconds, and the fastest dog wins. The sport has a long history, with origins dating back to ancient times. Today, Greyhound racing is popular in various countries, including the United States and the United Kingdom. However, it has faced criticism regarding animal welfare, leading to increased regulations and calls for ethical treatment of the racing dogs.
