Horse Respiratory Advanced: Heaves Management and Quality of Life

Severe equine asthma, historically known as heaves or COPD, is a progressive respiratory condition requiring lifelong management to maintain acceptable horse welfare.

Key Facts

Severe equine asthma affects approximately 5% of adult horses in temperate climates and is associated with stable management
Clinical signs include visible abdominal effort at rest, chronic cough, flared nostrils, and exercise intolerance
The hallmark heave line — a muscular ridge along the flank — develops from chronic expiratory effort
Environmental management alone can achieve clinical remission in mild cases but is rarely sufficient for severe cases
Bronchodilators including clenbuterol and albuterol provide acute relief; inhaled corticosteroids provide maintenance control

Welfare Considerations

Severe equine asthma welfare management requires a commitment to permanent environmental modification combined with pharmacological control. Horses with severe heaves cannot achieve acceptable welfare quality in traditional stable management — they require permanent turnout or minimally dusty housing. Inhaled medication delivery via equine nebuliser masks achieves good control with fewer systemic effects than systemic administration. The welfare prognosis with optimal management is good for quality of life, though the condition is not reversible.

What You Can Do

Ensure horses with heaves have permanent access to turnout and never return to high-dust stable management
Work with a veterinary respirologist to develop an inhaled medication protocol for horses with severe asthma
Monitor respiratory rate at rest as a daily welfare indicator — elevation above 20 breaths per minute warrants veterinary assessment
