Has your little guy recently has his bordatella immunization, or has he been around any other dogs (even a trip to the vet) where he could have gotten kennel cough? It could also just be a little upper respiratory infection, it could be an allergic reaction to the new food (they sometimes will react to rice and other grains as well), or it could be the Nutrical. It's really a guessing game.
For his wheezing, try running your shower with really hot water, bathroom fan off (if you have one), door shut and sit in the room with him. The steam will help him breathe better in the meantime. If he keeps wheezing, I'd have the vet at least rule out kennel cough or an URI and then you'll at least know it is highly possible it is the nutrical or his food. Good luck and keep us posted.
