I'm fairly new to the wonderful world of yorkies, but from my experience with my two, you just can't predict what size they will be. Rily started out following the chart to be around 6 pounds. He had a growth spurt after he was neutered and weights around 9 pounds now at 9 months. Saydee started out tiny, grew fast, but now at 5 months she seems to be slowing way down. She has been around 5 pounds now for over a month. I also keep height and length records. Neither have grown much since before Christmas. I believe each yorkie is different and you just can't know until they are done.
