So as some of you guys know, I recently switched Wolfy from a raw food diet to Natures Variety Instinct. The transition went smooth, he liked it, there were no stomach issues or anything. Lately he's not eating it. He's running around like a nut, playing, being himself, he's not sick, he went for his regular check up with the vet on Friday and everything went great. If I give him anything else he will eat it. The Natures Variety has been sitting in his bowl for 4 days. Do I have a picky eater? Should I try a different type of food?
