Laminitis Prevention in Horses: Diet, Management, and Early Intervention

Laminitis is one of the most painful equine conditions. Prevention through careful dietary and management practices is far more effective than treatment after onset.

Key Facts

Laminitis involves inflammation and disruption of the sensitive laminae connecting hoof wall to pedal bone
Grass laminitis triggered by high non-structural carbohydrate intake is the most common form
Ponies, native breeds, and overweight horses are at highest risk of pasture-associated laminitis
Endocrine laminitis associated with PPID and equine metabolic syndrome accounts for a growing proportion of cases
Dietary management including restricted grass access and low-sugar forage is the primary prevention strategy
Grazing muzzles reduce grass intake by 75-80% and are effective prevention tools for at-risk horses
Early clinical signs include digital pulse, heat in feet, and characteristic laminitic stance with weight shifted back
Prompt veterinary intervention within the first 24 hours of an episode significantly improves outcomes

Welfare Considerations

Laminitis causes intense pain from the inflammation and separation of sensitive foot tissues, and in severe cases causes rotation or sinking of the pedal bone through the hoof — a welfare catastrophe that can necessitate euthanasia. Chronic laminitis cases experience persistent daily pain that fundamentally degrades quality of life. The welfare tragedy is that most grass-induced laminitis cases are entirely preventable through appropriate dietary management. Owners who fail to restrict grass access for at-risk horses, or who ignore early warning signs, allow preventable suffering. The equine welfare community has consistently identified laminitis management as an area where owner education produces the greatest welfare improvement per intervention.

What You Can Do

Restrict grazing for ponies, native breeds, and overweight horses — particularly in spring and autumn
Use a grazing muzzle during high-risk grazing periods for susceptible horses and ponies
Test horses with suspected PPID or EMS and manage endocrine conditions to reduce laminitis risk
Learn the early signs of laminitis: digital pulse, warm feet, reluctant movement, laminitic stance
Call your vet within 24 hours of any suspected laminitis episode — early intervention transforms outcomes
Work with your farrier to provide appropriate supportive shoeing during and after laminitis episodes
