What brand of food are you currently feeding her? If you are feeding a lower quality diet, I would recommend switching to a higher quality, grain free chow. Some good one’s are Blue Buffalo Wilderness, Taste of the Wild and Orijen. I personally feed my pit Zoey Chicken Soup for the Dog Lover’s Soul. It is not completely grain free, but it does have a lot of high quality ingredients and no nasty byproducts or fillers. Also, it is the most affordable of the high quality dog foods. I know a few people whose dogs have had skin problems (specifically hot spots) which have completely cleared up upon switching to a more high quality food. Let me know if this works for you,
