If you feel you have a SUPER specimen for a mix breed, I still wouldn't breed it. The problem w/ mixed breeds, especially first generation (we're talking genetics) have LOADS of recessive genes that can poses MANY complications for the offspring when bred, I don't care to who. Do you really want to be part of that? Theoretical situation: You've got two pups that were born live. They go to their new home and everyone is happy/healthy and they fall in love. Only to turn around at 8 months and discover that their pup has died due to unknown issues. YES, this can happen in any breeding, but we're talking about increased odds here. If it's a chance you're willing to take, that's fine. Obviously people have been doing it for years (doesn't make it okay, but it has been done successfully).
On the flip side, if you're serious about breeding and it sounds like you are. BRAVO! You seem to care about the health and temperment of your breeding stock. It sounds like you've also decided that these dogs have something positive to offer the breed, have you shown them in obedience or any avenue in regards to AKC? That's fine if not (jmo that it should be a requirement for breeding stock). I applaud you on offering a health guarantee (2 years to life?) for your pups and will have the health screenings done prior. If you get a bitch as a pup, you should wait another TWO years minimum before you can get this program off the ground.
What ever route you decide to take, I'm posting this not to attack you, just to voice the concerns that everyone else is already thinking.
Please don't run off because of this post, there are loads of people here that are willing to help, just know where "we" come from because there are a large handful of us that do compete and feel it be a requirement to put your dog before a judge on more than one occassion in order to benefit the breed!
