Horse Rug Use and Welfare Considerations

Horse rug use requires careful assessment of thermal needs, freedom of movement, and the risks of overheating and skin problems associated with inappropriate rugging.

Key Facts

Horses in good body condition can withstand temperatures as low as minus 15 Celsius without rugging
Native breeds including Highlands and Exmoors have evolved for severe weather and often need no rugs
Inappropriate rugging causes overheating, sweating and skin condition problems
Rugs prevent access to natural weather tolerance mechanisms including piloerection
Heavyweight rugs restrict movement and can cause pressure sores at contact points
Horses in light work or good body condition are often over-rugged relative to welfare need

Welfare Considerations

Horse rug use is often driven by owner anthropomorphism rather than horse welfare need. Horses that appear cold to humans may be perfectly comfortable, and horses that feel warm to touch under heavy rugs may be overheating. Assessment of rugging need should consider breed, age, body condition, clip status, access to shelter and actual temperature rather than owner perception of cold. Over-rugging restricts movement and natural thermoregulation, can cause sweating leading to chilling when rugs are removed, and prevents horses from using the wind and rain resistance of their natural coat. The welfare-optimal approach is the minimum rugging needed for genuine thermal comfort.

What You Can Do

Assess rugging need based on breed, body condition and actual temperature rather than owner comfort
Check under rugs regularly for sweating, rubbing and skin problems
Ensure rugs are correctly fitted and adjusted to prevent restriction and pressure sores
Consult with an equine professional if unsure about appropriate rug management for your horse
