What nobody seems to be understanding here is that "goldendoodle" and "labradoodle" mixes, in this case, are created for a specific purpose.
That purpose is to provide a service dog for disabled folks with allergies. What Puppyraiser does is what their name says, raise puppies until they are old enough to begin their guide dog training.
The way I see it, you can have it three ways:
1. Breed a whole butt-load of purebred standard poodles, which have a very low success rate of becoming service dogs due to unsuitable temperaments for that kind of work, which creates a large excess of dogs. But hey, it's okay because at least they are purebred!
2. Cross a standard poodle with either a lab or golden, which will produce some puppies with a hypoallergenic coat that someone with dog allergies can live with. Not all of the puppies will be allergy free, but many many more of them will go on to become service dogs because of the adjustment in temperament. This will result in less puppies being produced to fill the needs of the disabled population and results in less dogs being cut from the program because their temperaments didn't work.
3. Tell those disabled folks with allergies who would really benefit from a service dog in their lives that, no, they can't have one because producing a dog that fits their needs encourages the "designer dog" fad and results in more homeless animals.
101 Dalmations "made" BYBs start mass producing the breed to fill the demands of the ignorant public. Does that mean the movie should never have been made? What about Lassie? Rin Tin Tin? Snowdogs? Wishbone? In my opinion popularizing any breed or mix will lead to them becoming in demand, and overbred by BYBs as a result. Service dog organizations are probably the most honorable kind of dog folks out there, and I hardly think that they should be held responsible for the stupid choices of ignorant people who treat animals like fashion accessories. I don't care if they are treating a golden/poodle mix or a purebred poodle as a fashion accessory, it is still an animal and it will happen with whatever breed or mix happens to be popular at the moment. Saying people shouldn't have that particular mix available as a service dog despite the great advantages, just because some people might want to get one from a BYB is just plain selfish.
To me, the answer is clear. There is a clear purpose to these crossbred dogs that benefits humankind which is not satisfied by any purebred out there, and therefore it is ethical to breed them for that purpose. Sometimes, a purebred dog isn't the most ideal dog for a job. The concept of guide dogs is a fairly recent one, and so it makes sense that there will need to be soem adjustment to the breeds of dogs out there in order to produce the most ideal dog for the job.
Puppyraiser, you are doing to world a lot of good by raising puppies for service dog programs, and I salute you whatever breed or mix you choose to work with next. If in fact, someone does want a goldendoodle after seeing yours, you could probably talk them into adopting one from service dog folks rather than going to a pet shop or somewhere else equally as nasty.
