I would encourage you to spay your girl and just love her as a wonderful companion.
Unless you've purchased her as a quality bitch, spaying will be your best bet. If you're going to breed, you need to be educated and well-prepared. You need to research and research, before making such a decision. Your girl needs be health tested and be a good representation of the standard to be a candidate for breeding. AKC registration does
not make a case for quality. Spaying will save you from the risk of serious issues and costs that can arrise, including loosing your girl. There is so much that can go wrong. It would not be a great experience if you were to loose your girl. Your baby will not be any less lovable if she doesn't have a litter of puppies.
