Another good food and some might disagree is Purina Pro Plan, Reilly has been on that from day one and it is excellent for him, and he really likes it, you can get it at feed store or petco. You also might try putting a stuffed animal of some kind in the crate with him, I did that with Reilly for a while, one designed for dogs, it calmed him down some and gave him something to snuggle up with.
