I've noticed, that when Charlie really gets at licking his butt, if I am around say 3 feet away, I smell this metalic oder coming from him.
It doesn't smell like poo. Which I would have thought I would smell from him lickin his butt.
Sorry for all the butt and fart posts today, I promise, I'm not a kid. lol
