They are also exclusively multigenerational, so theoretically breeders do not have to scrape the bottom of the barrel to find lab + poodle to make a mutt). Trust me I did a lot of research when my parents got their puppy, knowing full well that I was already biased against these crosses.
I'd expect them to prove it.
I did a look up of the supposed breed you mentioned earlier and every website I looked at bragged about having DNA or whatever - but there was no pedigree posted anywhere to prove it. It's again a big issue of misleading people with false claims.
If you have somebody breeding dogs true for 20-50+ years - that would be a huge deal. And I'd expect to see pedigrees posted to show that these are not just second generation dogs going on a third generation.
Besides the whole moral of breeding mutts who have no breed standard or any checks or balances to ensure they actually are breeding true to someting... there is also the problem where these dogs are not healthier than the parents and you have compounded issues because there were no health checks done on the parents and the history behind the parents was unknown. As generally is the case when you buy a dog from a petstore which got the dogs from a dog farm somewhere.
I had neighbors (they've retired and moved north by now) who originally had a toy poodle when they married. Wife was the owner of the toy poodle and she married a hunting type guy (and I mean big time - they had antlers hanging over their front door and a bear staring out one of the windows). When the toy poodle died, they bought a labradoodle. And the reason why was she loved her poodles, but he wanted a "real dog". So the doodle was a compromise.
Dog was about 9-10 years old when he was becoming very disabled from bad hips. And he also had neurological problems (either EIC which is a lab problem or it was a form of epilepsy) - these got pretty bad by the time he was a senior. He also had eye problems, might add.
Great dog. Hunting dog. Was a more rugged type of poodle. More bone than a poodle, more size (height) than a lab. But health was crap.
A lot of people jumping in and buying these mutts have no concept of good breeders in both goldens and poodles are actually doing to produce healthy and sound dogs generation after generation.
And in some cases, the only exposure some of these people have to either breed is really crapy bred dogs - so maybe they don't know any better.
Anyone who likes the look of doodles - they probably would be better of getting a breed like a Wheaton, Otterhound, or any of the other breeds out there which have a similar look... but are significantly healthier and sounder than a mutt coming from somebody who knows nothing about anything but buying any dog they can get their hands on and then spawning mutt-puppies to sell.
And to double down on my point, btw... the average person out there thinks that all you need in order to get well bred puppies is to put a purebred dog with another purebred dog, both papers, and let nature have its way. But the cold hard facts are that there's a lot of goldens out there and a lot of poodles out there - all who should never ever be bred. It's poor quality in structure, temperament, and type which makes these dogs endearing to their owners in some cases, but ultimately scraping the bottom of the bucket in the eyes of people who do have access to very nice dogs.
And I'm not kidding.
People who go to dog shows are bound to sit there at ring side and being all in awe over the beautiful dogs in the ring - thinking these are all very well bred dogs! But even in the show rings, there's dogs shown any day who technically should not be bred. Or would be a breeders ultimate last choice based on something about them.
That's breeders that put a lot of thought and extra effort in selecting studs for their breeding programs or where they buy their girls from. They are not just getting or using anything that happens to be the same breed as what they have or want to breed. This is selection.
I'm pretty sure I'm not the only one who has gotten approached by people who are looking for stud dogs at petstores or just walking downtown. And if I have time, I will prop an elbow and ask them questions about clearances going back the past 10 generations, I will ask about pedigrees the past 10 generations, and I will continue asking them all kinds of questions about their own dogs before I finally told them why it was no go. In a lot of cases, if the female is very VERY poor breed quality, there is no way I'd want my dog to be used. Doesn't even matter if the girl has clearances - I still would not OK that type of breeding. And so on.
