Long time pet owner first time owning a BP. About a week ago my bp started his shedding process with foggy eyes and what not. So I made him a humid hide (having trouble with humidiy at the moment but should be fixed next time clean change) 2 nights ago I noticed him trying to rub off his shed so I left him be but last night I decided to check on him to make sure his shed went ok. It seems like he had no trouble shedding the skin off his belly and sides but now there's still a good amount of dried skin on his back. Should I be concerned and what should I do to help him get the rest of the skin off his back?
