I came across a lady who sells yorkies, she says they are older than what they really are, trying to get more $$ for them. This is very bad for the puppy, to be taken from his mom before it's time. My Zander is approx. 5 lbs, he is very lightweight, easy to carry, cute, adorable, well mannered, I could go on
... he was in the ballpark of 700. Good luck and be careful.
