Just iodine, the scab is dry currently and not weeping. My neighbor thinks frostbite but usually the outter edges are swollen more than the interior. I do worry for the ear. Everyone else is telling me to wait til it's gunky before any further treatment. I can tell it bothers him. He tries to itch it with his rear foot. Aside from the scab and inflammation you never know anything was a miss. He eats and plays and no pus or wetness. Poor kiddo
