Jackson is 1 1/2 and pretty picky. He has never eaten his food when he's home alone, it's never touched, even though it's out for him all day. He literally just sleeps when nobody is home. He's never had an accident, or chewed, or played with toys, or anything when we're not home. It's not until someone gets home that he will chew his bones, eat his food, etc.
My picky boy loves his Acana and Nature's Variety Instinct. Those are the 2 foods that have worked best for us and that he loves the most
He will usually go over and munch on dry food around lunchtime and for dinner (around 6pm) I give him some of his dry food mixed in with wet food and he eats the whole thing up!
