Hi Maria,
I am new to the yorkie talk forum, but not new to yorkies .....
This is my first post on the board, and thought I could suggest to you on trying your new little boy on Royal Canine "Yorkshire" food. All of my dogs have always loved it and I ended up having to take some of my show dogs off of this food because they would gain TOO much weight on this food.
Best of luck to you with him ...
Your dogs are beautiful!
