Appropriate sedation for equine veterinary procedures is a welfare necessity that reduces fear and pain, enables safe examination, and prevents injury to both horse and handler.
Performing painful or frightening veterinary procedures without adequate sedation causes acute suffering and lasting behavioral consequences in horses. Horses subjected to fearful procedures while conscious without sedation undergo classical fear conditioning that makes future veterinary handling increasingly difficult, creating a cycle of worsening welfare. Appropriate sedation reduces the subjective experience of the procedure, prevents injury from struggle, and protects the veterinarian. The welfare case for routine sedation of horses for invasive procedures is now well-established, and failure to sedate when procedures warrant it represents a welfare failure justified by neither cost nor animal welfare.
