Face palm smilie?
You place yourself in a conundrum. A truly reputable breeder would never never never sell or stud a male to you to breed for the reason you mention above.
So...if you buy/find a male for the purpose of breeding you will not be dealing with a reputable breeder.
Please please please don't do this. Every week, every day I have a parade of local,broken, starved, sick and homeless german shepherds being tagged on my FB page. They too were produced by someone who was breeding for the wrong reason. Our local rescue can't pull and find fosters for them fast enough and they often die in 'the room' where they are put to death.
Please please please don't breed your female, get her spayed, love her and enjoy her.
