Cold back syndrome in horses — acute pain and resistance when first mounted — is often dismissed as behavioral but has genuine pain-based welfare implications requiring investigation.
Cold back syndrome represents a welfare concern when pain-based presentations are dismissed as behavioral and horses continue to be ridden through acute discomfort. The resolution of signs after warm-up does not indicate absence of pain — it reflects physiological changes (muscle warming, increased circulation, pain accommodation) that reduce behavioral expression. Horses showing consistent cold back presentations deserve thorough welfare investigation before any behavioral intervention. The welfare-positive approach to cold back investigation proceeds systematically: saddle fit first, then spinal and musculoskeletal evaluation, then gastrointestinal assessment. Management adjustments including warm-up protocols, groundwork before mounting, and physiotherapy reduce welfare harm during the diagnostic period while investigation proceeds.
