I touch food to my froggies nose and they take it no problem. He feels lousy right now. Dont push it. Another thing, get some undyed unflavored pedyalite. That is very good for a sick frog as it has electrolytes in it. Use a small amount added to the bath water, not straight. I dont remember how much in water, I'm sure someone else can tell you.

If you want to use neosporin get the kind without pain killer. Otherwise it will kill frog. Good luck with him.
