Horse Laminitis: Pain, Prevention, and Long-term Welfare

Laminitis is one of the most painful conditions in equine medicine, causing severe laminar inflammation in the hoof that can result in permanent damage and significantly impacts quality of life for affected horses.

Key Facts

Laminitis affects an estimated 7-15% of horses over their lifetimes, making it one of the most common serious equine conditions
The condition involves disruption of blood flow to the sensitive laminae connecting the hoof wall to the pedal bone
Severe acute laminitis causes rotation or sinking of the pedal bone through the sole — a catastrophic welfare event
Three main causes: carbohydrate overload (pasture grass or grain), endocrine disease (PPID/EMS), and systemic illness including colic
Equine Metabolic Syndrome and Pituitary Pars Intermedia Dysfunction (PPID/Cushings) are major underlying risk factors
Laminitic horses often appear reluctant to move, adopt a characteristic leaning-back stance, and have bounding digital pulses
Emergency management includes removing the triggering factor, analgesia, restricted movement, and deep supportive bedding
Therapeutic shoeing with deep-seated frog support and rocker shoes can significantly improve comfort during recovery
Dietary management including removal from lush pasture and soaking hay to reduce sugar content is critical for prevention
PPID is now effectively managed with pergolide medication, significantly reducing laminitis risk in Cushingoid horses

Welfare Considerations

Laminitis causes suffering that owners who have not experienced it sometimes underestimate. In severe cases, horses are in agony with every step and may refuse to move at all. Chronic low-grade laminitis causes persistent pain that compromises every aspect of the horse's daily experience. Prevention is profoundly more welfare-positive than treatment — understanding the triggers, identifying at-risk individuals through metabolic screening, and managing diet and exercise accordingly protects horses from one of equine medicine's most damaging conditions.

What You Can Do

Restrict access to lush spring pasture for horses with metabolic risk factors — use grazing muzzles or strip grazing
Test horses over 15 years annually for PPID (Cushings) — early treatment with pergolide prevents laminitis episodes
Soak hay for horses prone to laminitis to reduce water-soluble carbohydrate content
Call your vet immediately if your horse shows laminitis signs — early intervention dramatically improves outcomes
Work with a farrier experienced in therapeutic shoeing for horses managing chronic or recovered laminitis
Maintain horses at appropriate body condition score — obesity is a major modifiable laminitis risk factor
