Greyhound racing causes thousands of injuries annually and has faced growing public opposition as welfare concerns mount about the sport's treatment of dogs.
Racing injuries include musculoskeletal fractures, ligament tears, and cardiac events. Dogs kennelled for extended periods show signs of boredom and frustration. The export trade moves dogs to countries where welfare monitoring is absent. Doping offences demonstrate that welfare considerations are sometimes subordinated to competitive outcomes. The business model requires large numbers of dogs, most of whom will not achieve sufficient wins to justify their keep.
