First, you shouldnt be breeding puppies. If you're responsibly breeding, you generally dont own both the male and female, you instead breed your female to someone else's male after doing a lot of research as to what is the best possible dog to mate your dog with in order to achieve the breed specifics. That means that you need to find dogs that are in the show circuit. And, you should ensure that your female is of proper breed specifications.
And if you dont have time to breed her, you SHOULDNT breed her. If you think that finding a proper mate for her is hard, wait till you have puppies. As someone who has hand raised 3 litters of puppies (all rescues), I can tell you that you never know what to expect. Sometimes the mother will do her job, but (especially in the cases of first time mothers) many will reject their litter or at least a lot of their responsibilities. And if that happens, you're on call for doing feedings every 2 hours, cleaning them, making sure they go to the bathroom (puppies dont do that on their own for the first few weeks of life), making sure they're comfortably warm, etc. And then once they're at a certain age, you have to start house training and puppy training. And (if youre a responsible breeder), you'll keep the puppies until they're at least 10 weeks old (to ensure that they've properly learned all they should learn by that point like bite inhibition, that they're completely weened, that they're properly socialized for their age and that they've started their puppy shots). Generally speaking, though, unless you have two well known pedigree dogs bred and a well established breeding program, you'll be holding on to those dogs for a while until you find them a good home.
And if you're doing this in any hope of making money, let me just tell you that raising rescues (so I didnt even have to deal with the prenatal bills), I spent 10-20% more on each puppy than I ended up making on the few who actually ended up in families willing to reimburse me (and if you're not a reputable breeder yet, you should expect the same kind of results, you might get a bit more money for the effort, but not much).
Please, dont get yourself into breeding without fully understanding what you're dealing with. That's how a majority of litters end up at the pound/in rescues. As cute and as fun as puppies are, they're a lot of work, and if you dont know what you're doing or you dont have enough time to devote to them, you could be in a lot of trouble.
