try the bland diet for a while until she feels better; that's boiled chicken or hamburger and white rice; no salt or seasoning
and after she feels better switch her to high quality natural food; free of corn and byproducts; try orijien puppy food, which is made in canada
; i am in the process of switching my dog from halo to orijien 6fish and she ate it all up today; i was surprised that she loves it and it has high quality natural ingredients. you can buy a sample bag from certain pet stores for 2 or 3 dollars.
