WELCOME!
What are the current weights of the pups? You can only guess at adult wts - but one rule of thumb is tripling their 8 week weight or doubling the 12 wk weight. Also, you could ask the weight of parents and the grandparents.
The babies are very darling, but I will say that their ears look a little out of standard to me, is it just me? If you're willing to pay $1500, you could probably find a yorkie from a show breeder.
