Hi - Welcome to YT!

As far as size goes - ya just never know and there's no guarantee.

So many people have found that they love this breed and want to breed them. The problem is that the majority of the people breeding the Yorkie are unaware of the complexity of this breed. Most are buying a female and male and then just breeding them without knowing anything about them and their "family line". Then what you get is a "box of chocolates".

There is a "standard" that they are suppose to be - just like every other breed - but most people don't even know what that is before they breed them. They just know that they want a cute little furry puppy.

Another difference is that with a Toy breed every little thing is more obvious. Say a Lab is bigger than the standard by a few pounds - most don't think anything of it. But if a Yorkie is a couple pounds over the standard - it's really noticable.

It is really important to know where and from whom your puppy came from. Only then will you know if there has been any problems with the previous generations.

Plus, it's just nature's way but you're always going to find - even with the best lines - that there will be a couple that seem to have come out of no where.... a big one or a real tiny one. Just happens.

Congratulations on your new pup! Wishing you the best with him!
