Look at the ingredients list on the bag and can to see what else besides lamb and rice is in there.
This site lets you compare foods and I saw chicken, beef, and egg in the Nutro foods.

You may want to try a food that has no beef or chicken in it such as California Natural Lamb or Wellness or Eagle rabbit, fish, duck, or venison formulas to see if she does better on those.
You might also ask your vet for a referral to a veterinary dermatologist for expert help in figuring out just what the problem is.
You can use Benadryl at a dose of 1mg per pound of dog but it needs to be plain Benadryl not a cold formula. Tablets are better than liquids usually as some liquids have alchohol in them.
Hope this helps you!
