First response Rainrot

摘要

Often, the first signs of rainrot arise just hours after a horse is brought in fromthe rain: Tufts of hair begin to stand upright in patches over his back, sometimes following the contours of the "drip line" where water runs off of his body. Or the tufts might appear on the legs, where he has been wading in deep, wet grass. The areas with raised hair feel warm to the touch, and the horse may flinch from contact. By the next day painful, tight scabs will have formed over pockets of yellow-green pus.
