I feed my three home made liver Yorkie Yummies. They are truly Yorkie sized, contain no wheat corn or oats and are irrestible. My three love them and Boo the Boxer is hysterical..... She will take a treat (you can fix at least 4 on the surface of a dime) and chew it up. She swallows milkbone treats, but she chews Yorkie Yummies. How funny can you get.
