For a week and a half now my frog has been acting very strange. He wont eat now and when i pick him up he opens his mouth to me and i can see something inside i think its all of its skin like instead of swallowing it just bunched up in its mouth. My instinct is to pull it out because its been there a week now and he is obviously having trouble with it. I was wondering if i shold go ahead and do that or could that hurt him?
