@lvoss:
Asking where someone got their dog is not "interrogating", it isn't hostile, or in any way nefarious.
Sorry, but it does come across that way in some instances - maybe because it's so quick. At a dinner party, you don't start the conversation by asking who a new acquaintance's parents are, before you ask about them and their spouse, job and home - or maybe you do. But that wouldn't likely encourage candor.
It is true if the response is that their dog was from a BYB, petstore, or a rescue that often the next statement is a plug for the Fanconi test. Again, this advice isn't done out of hostility, it is done out of genuine concern.
But at that point if they do not intend to breed what diference does it make? Sadly, the new pup may be likely to eventually have Fanconi. If it's a BYB or a rescue, what can they do about it at that point? There's no one to give it back to - even if they haven't already fallen in love and don't want to give up their baby. Yeah, at some point, it's probably a good idea to know what's coming. But when you're in the first stage of doggie-love, knowing that maybe they'll die at some point…it's kind of a buzz kill. And you can't change it, so why create that anxiety right now?
Just to be clear, my comments don't relate so much to this post. This OP was talking about breeding, and at that point IMO all bets are off and the expert breeders should jump in. I don't find anything bitchy about that. But I'm not sure I understand insisting that a new owner of a pet B that may be discovered to be a Fanconi risk needs to know that on their first day here. Let them enjoy the glow before they face the risks of losing their sweet pup from health issues that were determined long before they came into the picture.
I admire and respect the breeders on this forum - I'm just voicing my opinion that in cases unlike this one - where they asked about breeding - we might want to let folks settle in and enjoy some basenji love before we hit them with all the risks they may have unknowingly bought into.
