My opinion (and that's all it is
) is that it is a wait and see thing. There are so many different sized yorkies I don't know how anyone could possibly predict an adult weight. There are so many variances, just as there are in humans. Some are finer-boned than others. Some are longer than others. Some are stouter than others. Some are taller than others. Plus, on top of all of that you have some who eat a lot more than others and it also depends on what they're eating. As I said, this is just my opinion, but it is also a lifetime's experience with little doggies.
