My white lipped tree frog is such a good frog. Like a month ago, he seemed to develop some sort of injury on lip of his mouth. The only thing I can think of is that when he darted for some food, he injured it somehow. I have been keeping triple antibiotic ointment on it on a regular basis, but just when I think it is healing, he will shed his skin and it looks re-aggravated all over again. Is there anything else I can do for him, or any special brand of ointment that will help him heal better?

thanks so much
Dave
