Has anyone tried this? I have a very picky eater and I thought this sounded good. I have tried a lot of different brands and he gets tired of them after a few days.I thought he liked NB duck and bought 15 lb bag and now he just turns up his nose so I have to mix in wet food and sweet potatoes. I think I will just buy small bags now and rotate flavors. He is 10 and I guess just getting stubborn.
