Kind of jumping in late on this one, but the advice that has been given by everyone is excellent. Most people don't know how much it takes to be a breeder. It certainly is NOT a "business", you aren't out to make money like some people think so. I'm wanting to be a breeder, too but I know that you MUST simply have health clearances done on dogs. Your 'job' as a breeder is to want to help improve the breed, and in the future, eliminate some of those unwanted health issues that can arise, even at early years in their life.
Anyways, instead of breeding her, why not take up DockDogs, Agility, Rally, or even Obedience. If you need help finding a trainer in your area, there is a wealth of information on here of people who can find you a great trainer. In the long run, you'd be spending much less money than it is to be a breeder and you'd be having more fun spending time with your girl.
