My snake that had the mouth infection awhile back is about to shed again. I don't know if his recent shedding problems come from the mouth area being swollen/scarred, as I only saw him shed once before the infection. The past two sheds he's had some respiratory distress and generally acted strange, and if he follows his previous pattern he'll probably shed in the next day or so. He just went blue last night, and as of this morning I can see the vertical lines going down his belly.
I put a shallow tupperware dish with some wet paper towels in his tank, and I've been putting him in his water to soak every hour or so. He's been soaking a lot on his own as well. His skin actually feels noticeably soft, so this one should go fine.

I'm not worried right now about this one being retained but I'm just curious; at what point do you intervene and do something? I can definitely see retained shed being an issue for this snake in the future, so I feel like it'd be good to know when to step in and what to do.
