Very interesting thought. When I first started looking for my Yorkie, I had picked out a litter of puppies to go and view that came from a very large Yorkie Mom and Dad. Their puppies were priced at $1450. Then I saw Missy's picture and totally fell in love with her. Her parents are both tiny, and Missy cost me $995. So the smaller pups aren't always the most expensive. Maybe my experience isn't the norm? BTW, I picked Missy because to me she was the cutest, it had nothing to do with size
