I don't mean to be killjoy, but the growth chart didn't work for me at all. I'm sure it's accurate for some people...and inaccurate for just as many. It's basically a rough guide. Don't feel like there's something wrong with your pup if he/she doesn't follow the growth chart. I think it really depends on the parents, grandparents, etc. It is fun to look at & try to figure out how big your Yorkie will be at maturity, but I wouldn't put too much weight on it.
