Hello...I have a big yorkie too. He weighed in at 16.4 lbs yesterday at the vet. Just more to love. He is the sweetest dog I've ever had. I am glad he's a big boy. I know a lady that bought a brother and a sister from the same litter and the girl ended up weighing 4 lbs and the boy ended up weighing 13 lbs. And both the parents were small. That's why I've always heard you never know what size your yorkie will be until they get older.
