Hey! I have a picky eater on my hands too! Almost 5 weeks ago, I bought him Nature's Variety Instinct dog food (
Nature's Variety) he LOVES it! I highly recommend it! It's an all life stages food, GREAT quality ingredients! NV has the Instinct and Prairie kibbles. Jackson likes the Duck and Turkey flavor the best. Eukanaba is not that great of a food, actually. Check out this site:
