HEY! We are currently using LIFE4K9 Dog food and the biggest diff. is it's all OVEN-BAKED and man the allergies are gone with my two dogs. Everything on the mkt is extruded- (grease added after it's cooked and cooked at high steam/temps). My dogs love the cookie like kibble and we are so grateful we found it at the store. Finally real nutrition sense- we will only buy oven baked.
