I think most breeders would not allow someone to bring a strange dog to their home or kennel.

Keep in mind that some dogs, when they are not raised around other dogs, get very jealous and are protective of their owner and they don't bond with other dogs. Yorkies have a wide range of personalities. Some of very active, some are couch potatoes, some love other dogs and people and some don't. I have had yorkies that would get along great in the beginning and they later started fighting when they get jealous or try to establish dominance.
