Allergies!

Even though I realize it's suggested at this website that medical questions be referred to a vet, I'm searching EVERYWHERE and ANYWHERE for answers to a serious "allergy" condition and continue my search!

My two-year old bitch has had every test available including extensive blood panels, allergy shots, chiropractic evaluation, natural/hollistic vets, generic vets and eats the best diet possible, a raw diet, and still itches herself crazy!!! I'm deadly against prednisone but have no choice as it's the only thing that keeps her from putting holes in her body!
