Horse PPID Cushing's Disease Welfare

Pituitary pars intermedia dysfunction (PPID or Cushing's disease) is a common hormonal condition in older horses requiring lifelong management.

Key Facts

PPID affects an estimated 20-25% of horses over 15 years of age
The condition results from dysfunction of the pars intermedia of the pituitary gland
Classic signs include a long curly coat that fails to shed, muscle wastage and pot belly
Laminitis is the most serious complication, causing severe foot pain
Pergolide is the only licensed treatment and is highly effective when initiated early
Annual blood testing of ACTH levels allows early diagnosis before clinical signs develop
Management also includes careful dietary control and foot care

Welfare Considerations

PPID significantly impacts equine welfare through laminitis, muscle wastage and the discomfort of an unsheded heavy coat. However, outcomes with early diagnosis and pergolide treatment are excellent - many horses enjoy years of quality life post-diagnosis. The challenge is owner recognition of early subtle signs and willingness to pursue testing.

What You Can Do

Arrange annual ACTH blood testing for horses over 15 as part of routine health checks
Watch for delayed coat shedding in spring as an early PPID indicator
Work with your vet to establish appropriate dietary management including low-sugar forage
Ensure regular foot care and monitoring for laminitis signs in PPID-diagnosed horses
