The use of prohibited substances in equine competition compromises horse welfare by masking pain, enhancing performance beyond safe limits, and undermining trust in sport.
Doping in equestrian sport is a welfare issue as much as an integrity issue. When a horse competes on a masked injury or with its pain threshold artificially elevated by prohibited substances, the sport is exploiting an animal that cannot consent to the additional risk imposed on it. Masking pain allows injuries to worsen during competition that would have caused the horse to be withdrawn for veterinary care under normal conditions. Welfare-centered anti-doping policy focuses not just on detecting cheating but on removing the competitive incentive for welfare-compromising doping practices and ensuring that all therapeutic use of medications genuinely serves the horse health rather than the competitive interests of the owner or trainer.
