All you have to do is think that if you were breeding - would you let your babies go to a stranger (Pet Store) and not meet the new owners of your puppies and allow your puppies to mix with puppies that someone else had? I think not! So what kind of a person would sell their puppies to a pet store? Good questions.
I am in Georgia, but won't have any pups for awhile. I am showing and don't want to finish my two first. But if you have any questions I will be happy to help. I might not have all the answers. But always good to meet/talk to a person whom loves yorkies!
