Greyhound racing raises significant welfare concerns including high injury rates (fractures, muscle tears, cardiac events), doping with performance-enhancing substances, inadequate housing conditions, and mass euthanasia of non-performing dogs. US industry data reveal approximately 1,000 documented race injuries annually; actual figures are thought to be substantially higher. Florida banned greyhound racing in 2020 via ballot initiative, closing 11 tracks; several other states followed. The industry globally operates in Australia, Ireland, UK, and other countries with varying welfare standards. Australian racing authorities introduced mandatory reporting and improved kennel standards following 2015 exposés. Greyhound adoption programmes rehome tens of thousands annually; greyhounds are regarded as gentle, adaptable companion animals. Welfare organisations advocate for complete industry phase-out, while regulators seek welfare-improvement pathways.
