The vet suspects a food allergy for my 6-month old pup who scratches frequently, but shows no signs of skin damage and has been treated for skin mites and ear mites. The pup's on Hill's Z/D Ultra, fruits and veggies only for 6 weeks (vet's orders). I know he can't eat grapes, raisins, avocados, highly-seasoned veggies, and cherries with pits. Question is - what else in the fruits and veggie categories should be avoided? The vet did not mention anything else besides what's listed above in the second paragraph.
