I'd go with a butt bath, too. Poop on the skin is VERY irritating, which is probably what you're seeing; it can even cause sores. Trimming a pooper path can help tons; if that's not enough, Cavilon spray, now widely available as the new 3M first aid spray for critters and also first aid spray for humans, is an EXCELLENT skin barrier to keep poop and pee off the skin. It was created as a skin barrier for humans with ostomies. The hair must be short before use; otherwise, you end up with a gunky mess.
