John,
Um, I think you misunderstood me. I have no opinion on the subject of Labradoodles at all :D Not my area of expertise and all that. But on developing new breeds, there is a lot to consider.
I do believe that over the centuries, breeding dogs has always been done with an eye for profit and not pure altruistic reasons. Improving the breed obviously betters the health of the dog and therefore the output of the original purpose. Of course, I'm not referring to the current version of puppy mills. But finance did play a large role in developing breeds that reduced human or expensive animal labor.
Just to use as examples and obviously not inclusive:
Rottweiler (protecting tax money & pulling carts cheaper than horses),
collies & corgis (herding animals)
sled dogs (transporting goods to & from settled areas)
Gun, & Sight hounds (hunting for food & tracking down animals)
Bulldog & terrier breeds (made money in various "baiting & betting" schemes)
If the dog breeds didn't bring in some type of economic profit... either labor or monied, certain dog breeds would not have thrived. There are already extinct breeds just due to changing times and attitudes. Employment and customs have changed over the centuries, this affects breeds and their existence.
Case in point at the moment, is the discussion about the packs of foxhounds. Sure, they're bred for species improvement, but it sounds that if hunting is banned, a mass cull will occur. Where's the altruism and regard to morals there? If they don't earn their keep, they die. Hmm. (I know, I just set off a heated discussion for the exact reason, but basically it sounds as if the owners won't want to bother with the large packs dogs, if they can't practically use them)
Having a pet for pure enjoyment is a recent invention for those who are not wealthy. Vets had to focus more on livestock/horses, up to the 1950s and even now in certain areas, just because dogs as pampered pets were not common enough to make a living upon.
Developing and maintaining any breed consists of blending many reasons. Finance has always been within the mixed bag that helped to develop the varied breeds of dogs today. It's easy to get on a soapbox and complain that certain breeders aren't being moral enough because they aren't doing what one thinks they should be doing for that specific reason. I tend to believe that morality in regards to dog breeding is an extremely subjective virtue and always has been :D
just my humble opinion
