Use of whips in horse racing is one of the most publicly visible and contested welfare issues in equestrian sport, with growing evidence challenging its justification on both welfare and performance grounds.
Research indicates that horses experience pain from whip strikes and show stress responses including elevated heart rate and behavioral avoidance. The justification that whipping improves safety by maintaining responsiveness is not supported by evidence. Reform movements are gaining traction internationally, with several jurisdictions moving toward significant restrictions.
