Another thing, her food is not only making her itch, it is also probably making her not feel well. Feeding her Purina Puppy Chow everyday is like feeding a child McDonalds everyday. You definately should not feed her any dog food that comes from the grocery store. I am positive that if you change her food to something more healthy, you will start seeing results soon. If you have anymore questions, feel free to send me a Private Message! I've done a lot of research on dog foods and I will help you in anyway that I can.
