My little Herbert is injured, and needs some help.

He is quite frisky, which got him into this mess. He was "going after" Witwoo, one of my female Plains spadefoots. Usually when this happens, I try to pry the male off if the female keeps whining and he doesn't get it. As I got over there, I witnessed Witwoo get one good kick in with her spade, and she sliced Herbert's lower lip open.

I quickly removed him and treated his wound with Neosporin to keep it from getting infected. However, he won't learn his lesson. He keeps croaking and calling for another lady. Every time he expands his throat, he stretches his wound and prevents it from healing. I finally separated him from the other toads...but he keeps singing. I just can't stop him. His wound has gotten slightly bigger and I don't know what to do.

Any suggestions as to how I can get him to stop croaking so his wound can heal?
