Yep definetly shedding. If your frog is scratching at itself kind of franticly then he/she is having a bad shed. Usually it happens when humidity isn't high enough or the substrate isn't moist enough. Normal shedding they peel it all off in one piece into their mouth without issue. Kind of like they're pulling a sweater over their head. If he/she keeps scratching franticly at the face or back you may have to set him/her in his/her water dish and sprinkle some water on your frogs back and or face. Which ever spot is irritating him/her. The funniest part of their shedding is when they rub their legs together like they're trying to start a fire Lol!
