Well...
Hm...
No way in hell I'd ever consider a puppy from this litter. But...
Most puppy buyers aren't me. Or Puddles. Or Prism. We insist on the highest standards. But I'm coming to my regular (controversial) rant, here.
[rant]
Fact: There aren't enough well-bred puppies for all the puppy buyers. When all those well-bred puppies are gone, where do the remaining puppy buyers go? After all, this is a zero sum game. There simply aren't enough puppies for puppy buyers. So, when the music stops and they don't have a puppy, where can they go to get one? They can go to puppy mills, back yard breeders, pet stores...where else? Hm.
So, I suggest that "second tier" breeders be an option that we shouldn't chase people away from.

To my mind, 2nd tier breeders are those who do the 4 core clearances but little/nothing else. And while I'd like to see generations of clearances behind a litter, this breeder at least does the 4 (except for the practitioner on the cardiac clearance, which, though inadequate under the GRCA CoE, does have some value to my thinking). I'd say this breeder is on the borderline low end of 2nd tier.
Puppies from such parings often lack in type, litters lack consistency, and puppies are wildly unpredictable in structure, temperament, and suitability for original purpose. But lots of buyers wouldn't care about those things even if you educated them on these issues, and for them a 2nd tier breeder is perhaps something they should be willing to consider.
Here, you've told the OP our very valid concerns, and she doesn't seem to care. There will be a puppy available for her, and she has made up her mind. And since this breeder appears to be a (very low end) 2nd tier breeder, perhaps after voicing concerns we shouldn't discourage her too much. She has been educated and is making an informed decision. The parents have the four core clearances (though with practitioner on cardiac). Not everyone is going to get a well-bred puppy. So, for those who don't care about that, but are making an informed decision, and the breeder at least tries to do better than the generations previous...hm...I say wish them well. :shrug: Hard to say here, because this breeder is just clinging to the bottom edge of the 2nd tier, but still...
My humble (and controversial) opinion. Your mileage may vary.
Good luck with your puppy search, Miranda. I hope you get a wonderful companion.
