Clipping horses in winter allows exercised horses to dry quickly and avoid overheating, but requires appropriate blanketing and management to maintain thermal welfare.
The welfare case for clipping working horses in winter is strong - an unclipped working horse that overheats during exercise and cannot dry quickly risks chilling, respiratory infections, and significant discomfort. Clipping is welfare-positive when followed by appropriate rug management. Welfare failure occurs when horses are clipped and then inadequately rugged, leaving them without thermal protection in cold weather.
