Corn and wheat are common allergens but even if the itchiness isn't from the food, your dog can only improve from getting a higher quality food.
I feed Toki raw (Natures Variety, Stella & chewys) in the morning and grain-free Fromm at night. Toki's had the salmon a la veg, the grain free beef frittata and the grain free gamebird. She has done well on them! Fromm no longer sends you samples but they send samples to pet stores so find a local Fromm retailer and request samples from them. If you email Fromm, they will send you a $5 coupon. If it turns out your dog has a food and not environmental allergy, you'll probably want a limited ingredient food of some kind (like acana's singles line or blue buffalo basics) |
