It has been my experience that when someone is listing Yorkies in the newspaper for @ $500, it is usually what is referred to as a BYB, Back Yard Breeder. In other words, they have a female, bred her, and now selling the pups. In my opinion, these people are not breeding for the betterment of the breed, just to make a few extra bucks. Find a reputable breeder, you will pay more, but in the end you get what you pay for.
