Aw maaaan, if only this thread had been made a week later, I'd be able to link you to a super sweet blog post that I wrote on this very topic and for the purpose of being to use it on exactly this type of thread.
That post isn't scheduled to go live until next Monday though. BUMMER.
Anyway, short version of the answer is that you really can't get a mixed-breed dog into a good mainstream breeding program. No responsible, established breeder would use that dog, no matter how good his individual qualities might be. If you are in the U.S., the lack of papers is a death knell for using your dog in a good breeding program. Anybody who did agree to breed their female to your dog would be highly, highly suspect.
Sorry. For a lot of reasons, I wish I could give you a different answer, but that's the way of the world.
