I don't know much about breeding yorkies and I'm a new yorkie mum however I do know that surely weight shouldn't matter. And how come people estimate potential full weights? I saw my Addies mum and dad, dad was the heaviest and weighs 3.8lbs. Addie is 12 weeks old and is currently already 3lbs. So not likely to be mum and dads size.
Although mum and dad were small they seem super healthy
