The joys of a picky Yorkie. I agree with Patti, there are alot of high quality, holistic, and organic foods out there. Just ere on the side of caution when you're testing out new foods. Remember, that a new food can be a shock to the system, so make sure you're mixing it in with your older food, and try to keep a can of pumpkin handy. Not pumpkin pie filling, but pure pumpkin. You can give your baby that, if his belly gets upset. Plus, I know, for a treat, I mix some pumpkin in with Gizmo's food.
good luck! Keep us posted!
