Chicken-Free Brand of Cat Food

Do any of you know which brand of cat food does not contain any chicken at all? I need to switch my cats. Very frustrated now as I found that my dog is stealing my cats' food. Her skin condition is back and I'm so angry. She scratched until her back is a bleeding sore. I had to get it cleaned, scrubbed and now, apply medication twice a day, again!! After all the precautions I took to remove chicken from her diet, she just had to go and do this to me.

She is now looking guilty after all the scolding I gave her during the medication, but it won't work. Once my back is turned, she tries it again. We tricked her into thinking we weren't looking, and she stole their food. Great. We've thought of many alternatives, but it's very inconvenient and tiring to keep her away from the cats. We're just gonna have to switch the cat food.
