As far as pedigrees go, I'm no help at all. If you don't have his pedigree, then don't breed him. That should be the very first thing you should have before considering breeding.
But how old is your dog? Does he have hip/elbow certification from OFA or PennHip? Does he have any titles? Obedience, conformation, rally, agility, flyball, etc.? Those are the first absolute bare minimums you should have/consider before wanting to breed.
