Over 100 million horses are kept in developed countries, with millions participating in organized sport — racing, show jumping, dressage, eventing, endurance, and polo. The financial stakes of elite competition create incentives that sometimes conflict with horse welfare. Regulatory systems attempt to balance competitive ambition with welfare protection.
Thoroughbred flat and jump racing involves significant welfare risks: catastrophic musculoskeletal injury (approximately 1.5 per 1,000 starts in flat racing; higher in jump racing), exercise-induced pulmonary hemorrhage, and training-related overuse injuries. Racing authorities worldwide are implementing changes: improved track surfaces, race entry restrictions for horses with health issues, and injury surveillance.
Rollkur (hyperflexion — training horses with the neck bent severely behind the vertical) is a controversial training technique used at elite dressage levels. The FEI (Fédération Equestre Internationale) prohibits hyperflexion of more than 10 minutes, but enforcement is inconsistent. Research documents physiological stress responses and behavioral aversion in hyperflexed horses.
Three-day eventing combines dressage, cross-country jumping, and show jumping. Cross-country jumping at speed creates high injury and fatality risk (approximately 0.4-0.6 per 1,000 horse starts). Course design modifications, ground jury veterinary authority, and penalty reforms have reduced fatality rates. Horse and rider safety are mutually dependent.
Performance-enhancing substances — corticosteroids, anti-inflammatory drugs, pain-masking agents — are used in competition horses, raising welfare concerns about horses being required to compete while managing pain or injury. Anti-doping programs (FEI Clean Sport) and medication rules aim to prevent welfare harm from inappropriate drug use.
Equine welfare is increasingly prioritized in sport governance. The FEI Equine Ethics and Wellbeing Commission (2022 report) recommended significant reforms. Social license for equestrian sport depends on demonstrable welfare commitment. Some sports face existential challenges from welfare concerns — greyhound racing has been banned in multiple jurisdictions.
