Greyhound racing industries in the US, Ireland, Australia, and UK have faced increasing scrutiny over welfare standards for racing dogs.
Greyhounds in racing industries experience welfare challenges from injuries, overbreeding creating surplus animals, and kennel conditions that restrict natural behavior. Racing injuries including broken legs, hock fractures, and cardiac events cause acute suffering. Kennel housing in individual runs restricts the social and exercise needs of highly athletic dogs. Overbreeding means each racing season creates thousands of dogs that cannot be placed in homes. Industry reform is uneven across different national racing industries.
