I agree with Matese that $600 for A Yorkie in NY/New England where the asking price is for a Yorkie is much higher than almost anywhere else in the country -- this is not a quality breeder. All pups are adorable, and the puppy in your pictures may be a full bred Yorkie, but she is 'off standard' for a Yorkie in terms of size, head, and maybe coat. I would ask to see the parents and top priority would be a health guarantee -- and whether or not you think this breeder will stand behind the guarantee.
