No hoof, no horse — the welfare science of equine foot health
Hoof health is foundational to horse welfare. Laminitis (rotation and sinking of the pedal bone due to inflammatory processes) is one of the most painful conditions a horse can suffer, and lameness is the most common performance-limiting problem in sport horses. Evidence-based hoof care — appropriate trimming intervals, shoeing decisions, and laminitis prevention — directly determines millions of horses' quality of life.
Laminitis involves inflammation and disruption of the laminar tissue connecting the hoof wall to the pedal bone. In severe cases, the pedal bone rotates or penetrates through the sole — one of veterinary medicine's most painful documented conditions. Horses with chronic laminitis shift weight to relieve pain, reluctant to move, standing in characteristic "laminitic stance." Prevention through diet management (limiting non-structural carbohydrates, avoiding lush spring grass) is far preferable to treatment.
The debate over barefoot vs. shod horses has welfare dimensions beyond performance. Research indicates: well-trimmed barefoot horses on appropriate terrain show better hoof mechanism (blood pumping through foot), better proprioception, and potentially better long-term soundness. Metal shoes provide protection on hard or rough terrain and support in horses with specific pathologies. The welfare-optimal decision is individual: terrain, use, conformation, and existing hoof condition all factor in. Regular farriery (every 6-8 weeks) regardless of shoeing status is essential.
