Blanketing or rugging horses is widely practiced but frequently misapplied in ways that compromise rather than enhance horse welfare.
Over-rugging horses is a widespread but underrecognized welfare issue. Many horses are blanketed based on human temperature perceptions rather than equine needs - horses with intact winter coats can comfortably tolerate temperatures far below what feels cold to humans. Horses wearing inappropriate rugs can overheat, causing sweating under the rug that paradoxically leaves them colder when the rug is removed. Ill-fitting rugs cause pressure sores, rubs at the withers and chest, and can restrict movement. Horses may also experience frustration and distress from wearing equipment that inhibits their ability to roll or move freely. Evidence-based rugging decisions consider the horse's coat type, body condition, access to shelter, and actual weather conditions.
