I think I freaked my wife out when I said he might weight 9 lbs. Apparently I over guessed though. We have a 2 year old female that is 5.5lbs. She is just about the right size. I think the boy may end up about 6-7lbs which is fine with me. Nothing against smaller yorkies but I also have a 7 year old boy and a 4 year old girl whom adore their dog, but they are still kids. My wife worked so hard to get this baby for me and I can't thank her enough.
