I could care less about weight, I wanted a Yorkie so badly and now I finally have my Molly and she could weigh 2 lbs for 20 lbs and I would love her just the same.  The only thing I ever cared about was that she was healthy and happy with me.  I think Molly might be one the big side cause she only 6 months and weighs 7lbs already.......Man she is still my little princess
