I have a yorkie-poo and so does Biddy's mom. But i'm not selling puppies. Kelsey's weight is at 9 1/2 pounds full size. She was very tiny as a baby. Dont be discouraged if your baby grows a little more than you expect. Yorkie-poo's and all other mixed breed dogs all come out different in size...so you never really know what your going to get. I'd love to see pics of your baby! And good luck to your friend....
