Horse Winter Laminitis: Recognition and Prevention

Laminitis can strike horses in winter, often linked to metabolic conditions like PPID and EMS, requiring proactive monitoring and management.

Key Facts

Winter laminitis is often associated with Pituitary Pars Intermedia Dysfunction (PPID, Cushings) in older horses
Horses with Equine Metabolic Syndrome (EMS) are at year-round risk, not just spring grazing
Cold-induced vasoconstriction may be a contributing factor in winter laminitis cases
Signs include a digital pulse, shifting weight, reluctance to move, and sensitivity on hard ground
Management includes dietary restriction, appropriate exercise, hoof support, and treating underlying conditions
PPID medication (pergolide) dramatically reduces laminitis frequency in affected horses

Welfare Considerations

Laminitis causes extreme pain within the hoof capsule. Winter cases can catch owners off-guard since the spring grazing association is well-known but winter cases less so. Horses with PPID or EMS require year-round vigilance. Early recognition, pain management, hoof support, and addressing root metabolic causes are essential welfare obligations for these vulnerable horses.

What You Can Do

Test horses over 15 years with unusual coat or body condition for PPID annually
Monitor for digital pulse weekly in horses with EMS or previous laminitis history
Restrict access to deep-bedded areas where horses can weight-shift if laminitis is suspected
Discuss pergolide treatment with your vet for PPID-positive horses before winter
Use hoof boots and deep shavings bedding to support painful feet
Call your farrier and vet at the first sign of increased digital pulse or heat
