Ok i know its a weird question, but I board my horse, and she has a waterproof blanket but its not on her right now. It's rainy and sleety outside. She does not have a shelter in her pasture and there are no stalls out there (My sister's horses have a shelter but they're in a separate paddock and haven't been introduced yet as my horse is new out there). Should I go out there and kind of towel dry her off, and put the blanket on? My sister says it does more harm than good if they are not completely dry underneath. My reasoning says even if she's damp, itll hold her body heat in and keep the cold wet rain off. What say you educated people?
