So, Riley has some kind of bite on his butt (like a chiggar bite) and he's being a
major drama king about it

He'll lay down for a bit then run through the house like a crazy dog...like he's trying to get away from whatever is there. He had a bath this morning, his tushy is trimmed (no, it's not razor burn) and there are no clingons...so...the next step is to put something on his little bum to make him feel better.
Anyone know what's safe to use?
