It is hard to guarantee what size your puppy will be full grown. I think thats why so many are disapointed when the dog they expected to be tiny ends up larger than they expected. As long as you realize that there is truely no way of knowing then you will not be disapointed.
I agree that you should look for perhaps the runt of the litter from two standard parents from a reptuable breeder. I am also one that has a smaller yorkie that is now 2 1/2 pounds (at over 9 months old) that was from standard size parents. The breeder thought she would be about 5 or 6 pounds full grown, I don't think its going to happen. Also do not get one from a breeder that breeds tinies to get smaller puppies, its not safe and not reputable.
All the best on finding your puppy!
