Now that season is changing she is shedding profusely again and I noticed a couple scabs where she has been licking her inner front legs too much. So, I started thinking back to homemade food.
Minimize what you feed. A single protein source (different than what you currently feed) and a single carb soursce. See if that solves the prob. Be sure no other snacks are feed either. Eventually you can add more in and determine what causes the reaction by introducing one new food source at a time.

If you feed animal organs, make sure it is from an organic source!!!!
