My 4 months old Lab won't eat his dog food. This has been happening over the past 3 weeks and we have taken him to the vet, who doesn't know why he isn't eating. He has an appetite and will eat treats and pretty much anything BUT his puppy chow. We even bought Iams (he was getting purina puppy chow previously), but he doesn't like that either. If I put something he does like in w/ the dry food he just licks it off the dry food. He probably is only getting 1-2 c. max a day of his dry food.

I don't want to keep buying food if he isn't going to eat it and I am getting desperate.
