Horse Cushings Disease PPID Management

Pituitary Pars Intermedia Dysfunction (PPID), commonly called Cushings disease, is a progressive hormonal condition in older horses requiring lifelong management to maintain quality of life.

Key Facts

PPID affects approximately 20-30% of horses over 15 years old
The condition results from dysfunction of the pituitary gland causing excess cortisol-like hormones
Classic signs include a long curly coat that fails to shed, muscle wasting, and pot-bellied appearance
Laminitis is a major welfare concern associated with uncontrolled PPID
Pergolide medication can effectively control hormonal dysregulation in most cases
Regular blood testing (ACTH levels) helps monitor disease control and adjust medication
Horses with well-managed PPID can maintain good quality of life for many years

Welfare Considerations

PPID causes progressive suffering through laminitis pain, muscle weakness, increased susceptibility to infections, and abnormal thermoregulation. The shaggy coat causes discomfort in warm weather, and associated laminitis can be excruciating. Horses with uncontrolled PPID experience a significantly reduced quality of life. With appropriate veterinary management including medication, dietary adjustments, and regular monitoring, welfare can be substantially improved. Early diagnosis is key to preventing the most severe complications.

What You Can Do

Have horses over 15 years tested annually for PPID using ACTH blood tests
Begin pergolide treatment promptly if PPID is diagnosed
Clip long coats seasonally to prevent overheating
Feed low-sugar, low-starch hay and forage to reduce laminitis risk
Monitor feet carefully and maintain regular farriery every 6-8 weeks
