Ouchies, that poor guy looks like he has something bad going on. Not only the ear, but he looks like he has had some major event happen to his face or head somewhere in his past. Half the side of the head atrophied is not a normal reaction to an infection in the ear.
Or did I miss a post about his head? Do you know why he is like that or did you buy him that way?
He sure looks like a sweetheart, poor baby. I hope he gets on the fast track to healing.
