Well, the rash is back. This time it is starting on her soft belly skin (where there is little hair). She has also been losing hair around her eyes and mouth. She doesn't seem to be itchy. Her ears seem a lot better since using Surolan and keeping them cleaner with Q-tips.
Roxy is onto the Iams full time now, and so far no difference. However, after opening the bag of Iams Mini Chunks I realize that she must have been on the Iams Toy Breed (smaller pieces) which is a slightly different recipe, so once she is done this small bag I will buy the Toy Breed stuff. I will leave her on it for a month to see if there is any improvement.
