I'm one of those people that believe only the best of the best should be bred. We have so many pet quality yorkies available now, and shelters are turning away dogs, please don't breed unless there is a real desire and passion there, then don't breed the dog you have, but find special breeding dogs and a mentor. Breeding should never be taken lightly, what you do effects so many people's lives for years to come. Here's a great link for those thinking about breeding, and it's so informative for those who just are looking for qualities in a good breeder.
