Greyhound racing involves systematic welfare concerns including injury rates, kennel housing conditions, and the fate of retired dogs at the end of their racing careers.
Racing greyhounds experience kennel conditions fundamentally at odds with their exercise needs when not actually running. Injuries including broken legs and muscle tears end careers and often result in euthanasia in jurisdictions without robust adoption programs. The gradual phaseout of racing in most US states has created a massive adoption demand that rescue organizations are working to meet.
