Horse Laminitis Acute Phase Management

Acute laminitis is one of the most painful conditions horses experience. Rapid, appropriate management during the acute phase can prevent permanent structural damage.

Key Facts

Laminitis involves inflammation and disruption of the sensitive laminae that support the pedal bone
In severe cases, the pedal bone can rotate or sink, causing chronic pain and requiring euthanasia
Dietary carbohydrate overload, endocrine disease, and systemic illness are leading causes
Bounding digital pulses and heat in the hoof wall are key early warning signs
Immediate removal from pasture and box rest on deep bedding are first-line emergency responses
NSAIDs like phenylbutazone provide critical pain relief during the acute phase

Welfare Considerations

Acute laminitis causes intense, unrelenting pain that horses cannot escape — they cannot rest the affected limbs the way humans would offload an injured foot. Welfare in the acute phase is dominated by pain management and preventing progression to rotation or sinking. Owners must understand that box rest is non-negotiable; even small amounts of movement on acutely inflamed laminae can tip a reversible case into permanent structural damage. The welfare cost of undertreated acute laminitis is enormous.

What You Can Do

Learn to check digital pulses and hoof temperature so you can detect early laminitis
If you suspect laminitis, call your vet immediately — this is an emergency
Remove the horse from pasture and confine to a stable with deep sand or shavings bedding
Support the frog with pads to redistribute weight while waiting for veterinary assessment
Ensure adequate pain management is prescribed and administered consistently
Work with your vet and farrier on a long-term management plan for horses with recurrent laminitis
