As long as she's healthy I've had yorkies in the 10-12 lb range when fully grown. My current yorkie baby, in theory based on her parents and the growth chart here, should be around 6-7 lbs or at least not much more than 8 when fully grown. I'm trying to be more careful in feeding her properly as all our pets we've had had become overweight at some point in their life, fortunately they lose it in the later years. Right now our older jack russell is at a decent weight for her size, but our smaller one is fat X.x;
