American Toads vomiting up dead skin?

[Trout hunter]

Hey guys, sorry for posting so much but this one is kinda urgent. I think I have two toads that are vomitting up what looks to be like dead skin. I was helping them get it out of their mouth but I realize that I could be hurting them so I will stop doing that, but the only reason I was doing that was because they would eat the dead skin or whatever it is again. It is also covered in dirt. I didnt take a picture of it and I shoudl have, but can't do anything about that until it happens again. Does anyone know what they are doing or what it is? These are the first toads I have ever had (I do have frogs but they never have done this before. What should I do? Thanks guys! If you need anymore info just ask!

I could be wrong but it sounds like they are just shedding their old skin. When they do this they eat their old skin and repeatedly open their mouths and which I guess kinda does look like vomiting. If they are shedding do not try and pull on the skin as it may hurt them
