Well it has been a week since I changed Dixie's food. Switched her to Natural Balance LID lamb meal & brown rice.
Amazing the difference in her appearance, behavior and energy level. Her face is no longer torn apart from her constant scratching. The scabs she had are gone, now I have to wait for hair to grow back and she isn't scratching herself to death. Her ears are looking good for what they looked like before. One thing I am keeping an eye on is the yeast buildup she had. It is at a minimun on her face, nothing that can't be handled with done daily cleaning.
