> I had checked with the breeder that the KC papers would not be endorsed
This for me would be a reason not to buy. Breeders who care about their bloodlines and the breed tend to endorse so that only litters from dogs suitable for breeding are registered.
Most would want to see how the dog matures and also that it passes all relevant health tests and that the owner will be the kind of person that will breed responsibly, not something anyone without a crystal ball can tell at 8 weeks, even with the best pedigree.
Only a small proportion of dogs are going to be suitable for breeding, and even fewer owners suitable to be breeders in it for the long haul.
Most good breeders sell a puppy as suitable to be a companion, and the descent or otherwise of testicles should not impact on this. The fact that there is a higher risk of tumours is really only the same as there being a higher risk of tumours in intact bitches (doesn't mean either
needs to be neutered), or more prostate cancer in neuters etc, yet neutering is still waht many choose to do.
I know no breeder that would sell a pup as a breeding animal, or for that matter show or working, only that a pup shows potential.
If the breeder is as described i don't believe they are a true breed enthusiast.
Do they belong and take part in breed club activities?
