He's definitley not going to be a tiny yorkie, but his weight at maturity is anyone's guess. I placed a little guy early this year and he was over 2 1/2 lbs at 10 weeks if I am correct. He is way over 7 lbs now. Amazed me. I think the owner really had their heart set on a tiny yorkie. But since I don't breed for that I'd much rather hear that he's a bigger yorkie, than a tiny, sickly one. I tried to explain that he wasn't going to be a tiny yorkie, but I think she fell in love with him at first site regardless. It's so hard to predict. We can guess and guess but some of them will really fool us!
