Just because he comes from a line of 'top' pedigree dogs, does not mean that he has inherited their finer points. Although good dogs do slip the net and get offered to pet homes, most good breeders can spot a puppy with potential and will either keep it themself, or only offer to a show home. In any litter there are usually only one or two, occasionally a few more, that show the potential to win in the ring, and the rest are sold to pet homes, even though they may have champion winning parents. I doubt you will find any breeder willing to use your dog unless he has proved himself in the show ring, and been tested on one of your own bitches, if you have one, so they can see what kind of puppies he throws.
But, you can support one of the many BYB's around, and run the risk your 'perfect' dogs puppies being sold to unsuitable homes and adding to the rising population of dogs in Rescue.
We may all think our dogs are 'perfect' but in reality, as far as the Kennel Club breed standard is concerned, there is no such thing, but some dogs fit the blueprint closer than others.
