Cutaway Saddle Pad
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.
