Horse Senior Care: Managing Multi-System Decline with Quality Focus

With good nutrition and modern veterinary care, horses routinely live into their 30s. Senior horses require proactive management of dental disease, metabolic conditions, pain, and social needs to maintain quality of life.

Key Facts

Horses are generally considered senior at 20 years, though individual variation is substantial
PPID (Pituitary Pars Intermedia Dysfunction or Cushing's disease) affects an estimated 20-30% of horses over 15
Dental disease in aged horses causes quidding (dropping food), weight loss, and pain from missing or worn teeth
Senior horses often cannot compete with younger herdmates for hay, requiring protected feeding areas
Equine Metabolic Syndrome and associated laminitis are common in older horses and ponies
Pergolide medication for PPID dramatically improves quality of life and reduces secondary problems
Annual PPID screening using ACTH testing allows early treatment before clinical signs become severe
Regular body condition scoring using the 9-point Henneke scale guides nutrition management

Welfare Considerations

Senior horse welfare requires owners to transition from performance-focused to quality-of-life-focused care. Conditions like PPID cause subtle early signs - slightly longer coat, increased drinking, reduced performance - that are easily attributed to normal aging. Early detection and treatment prevents the suffering of advanced disease including severe laminitis and immune suppression. Dental care is equally critical - an aged horse with poor dentition who cannot extract nutrients from forage will slowly starve despite having adequate food available. Social management deserves attention: senior horses may be harassed by younger herdmates, preventing food access and causing chronic stress. Protected feeding, appropriate companions, and regular pain assessment should be the foundation of senior horse care.

What You Can Do

Schedule twice-yearly veterinary examinations for horses over 20, including ACTH testing for PPID
Have an equine dentist float teeth every 6-12 months for horses over 15
Monitor body condition score monthly and adjust nutrition accordingly
Provide protected feeding areas where senior horses cannot be displaced by younger animals
Assess for signs of pain including altered posture, reluctance to move, and facial grimacing
Use the Equine Quality of Life Scale to make objective end-of-life assessments when needed
