Any horse that’s ridden hard might develop a sore back, which might have something to do with the way he’s ridden or the tack used on him. One possible solution is to use a cutaway saddle pad made with an opening to fit over sore spots on the withers.
However, there’s another use for this type of pad. A second area that sometimes becomes tender on a sore-backed horse is right over his rear vertebrae between his kidneys. To help relieve soreness there, turn around the cutaway saddle pad, with the cutout portion to the horse’s rear end. Doing so prevents the saddle skirting and its lacing from rubbing on his rear vertebrae, so you can continue to ride while allowing the horse to heal.
