Horse Laminitis: Managing a Painful and Complex Hoof Condition

Laminitis is one of the most painful and feared conditions in horse medicine, causing severe hoof pain and potential permanent damage without prompt and appropriate management.

Key Facts

Laminitis involves inflammation of the sensitive laminae within the hoof, causing extreme pain
Dietary triggers — particularly rapid access to rich grass — are a leading cause of laminitis
Ponies and native breeds are disproportionately susceptible to diet-induced laminitis
Severe laminitis can cause rotation or sinking of the pedal bone through the sole of the hoof
Early detection and treatment dramatically improves outcomes; delay risks permanent structural damage

Welfare Considerations

Laminitis is one of the most welfare-significant conditions in equine medicine because it causes extreme pain and can lead to euthanasia in severe cases. The condition is often preventable — particularly the dietary form — through appropriate weight management, restricted grazing, and monitoring of grass sugar content during risk periods. Owners who recognize the risk factors and take preventive action save their horses from enormous suffering. When laminitis occurs despite prevention, immediate veterinary attention and strict rest are critical welfare interventions.

What You Can Do

Restrict access to lush spring grass for ponies, donkeys, and overweight horses
Maintain horses at healthy body weight through appropriate diet and exercise
Learn to recognize early laminitis signs: heat in hooves, pottery gait, leaning back on heels
Never administer bute (phenylbutazone) without vet guidance and confuse pain masking with recovery
Work with a vet and farrier team on long-term management for horses with a laminitis history
