There is a big difference with breeding a dog to fit some purposes and having those dogs for the same purpose. They were bred years and years ago, and the point is that people want to preserve the breeds now. Just because a dog was bred for hunting, and people don't use them for hunting anymore, doesn't mean that we should change the breed so that they don't care about hunting anymore! But they were bred for that, and it's their standard, and what good breeders are trying to maintain.
In the case of labradoodles, the project was stopped before they even got to agree on a standard, so anyone can mix any kind of lab and poodle and get a labradoodle. That's the difference. It doesn't matter what people do with them, it's the reasons they are bred for that matter, and in their case, there is no good reason to breed them, except that people want them. Thus, there is no other reason than to make money by selling them to people... Please, if you find any other good reason to breed them, tell us. I'm no expert of breeding, but I know that all the breeds we have now were created because they can do something better than other breeds. What can a labradoodle do better than another breed?
It's sure we won't solve any issue in the thread, but as you said, we can give information, and it's what we did. I love mixes, and I am completely against breeding a dog just because someone wants them! I would love to see a golden/newfoundland mix, am I going to start breeding them to get a 'newfgolden'? No, because it's totally irresponsible. It's exactly the same thing with labradoodles.
And no, the most important part isn't that everyone gets a dog that fits their life, but that they make their decision responsibly and don't condemn hundreds of other dogs by doing so. There are probably hundreds of dogs out there that would be perfect for one person, why get one that was only bred by unscrupulous people who are just in for the money? It's extremely selfish to think that someone should just get a dog that fit his life, his wants, and his needs, without caring at all that lots of dogs might suffer from it.
