Perhaps you need to switch her to a food with a single protein source and no wheat corn or soy...or other chemical additives.
The Nutro is a better food than Pedigree (which is filled with icky stuff), but since neither works for her, maybe you need to look into eliminating most known allergens in her diet (specifically wheat, corn and soy).
Some foods that have a single protein source are made by companies like Eagle Pack Holistic, Timberwolf Organic, Wellness, etc. There are threads about feeding in the food section.
They're not inexpensive, but they're a lot less than Vet bills for years while you're trying to control your girl's problems. And...she'll be healthier and happier too!! That's the most important thing.
You might want to try a raw diet....and you can find info on that as well. Plus many here will be able to help you.
You may also want to start her on some Omega 3's. We use Timberwolf Organics Pharmaceutical Grade Salmon oil. But there's another really good liquid salmon oil that others use too. (I just can't remember the name of it).
Good luck with your girl. I think that perhaps a change in diet, and some good supplements for her coat could really help. Remember, tho...it can take a month or more to see a real difference. The toxins have to get out of her system first.
PS...when you switch her to a better food, don't forget...no wheat corn or soy in her treats either. No bread, no pretzels, no pizza crust, nothing like that at all. Wellness makes great wheat corn and soy free treats. So do other companies.
Also...to find these foods, you need to go to a small pet supply store and ask for them. PetSmart doesn't usually carry them.
