Oh thank you!My Yorkie recently got his haircut and the groomer said he is at a healthy weight!!

There is no such thing as a "toy Yorkie." Its a designer title. The AKC website lists the correct size and weight a quality bred Yorkshire Terrier should be.

Actually he might not be a toy yorkie,because he doesn't seem to be as small
