bearded dragon is about three years old, he was a rescue so I don't know for sure. He eats all his worms, sometimes his greens, and is very active and alert and cuddle. But he had concerning white patches that I believe are retained shed. I've read great things here about treating retained shed, but the problem is that the shed is right on his face and under his chin. I've ordered shedding aid and plan to mist and bathe him a few more times a day. He already has a water dish large enough to play in and completely submerge himself-he has a blast in it. But it's not enough, how can I safely treat this?
