I second Canidae. Loki had all sorts of tummy troubles as a puppy until we found Canidae! There is now a Lamb & Rice formula I believe. ALS has chicken & lamb. It may not be the chicken he's allergic to. Just try the Canidae. Call them - they will send you samples!!!

Also, just so you know, high quality canned food is fine for their teeth. It's the sugar/junk in all the low-quality canned that is bad for them. Most of us on here brush our Yorkies' teeth. That will help the most! We use mint Petzlife toothpaste.
