You know... this question has made me stop and think. I've never thought of those "designer dogs" aka mixed breeds, aka mutts, as actually coming from a breeder. What comes to mind for me, is puppy mill, or (and oh, how I hate to use this term) byb. I coulda swore the whole point of a breeder, was to try and meet the standard while keeping health, build, and temperment in mind. At least, that's my loose definition of it, I realize some have a more stringent definition in mind. I don't see how you can meet those goals with a mix, as you can't really guarantee, much less plan the outcome. Hmmm... have to think about this one awhile. Edit: Thank you EverCavalier for providing that informative link. I really liked their standard! As so much of it was this or that, nothing definite, and another chunk of it was "as yet to be determined". What a great standard. If they stick with it, perhaps in a couple decades they'll have the kinks worked out, and a new breed might emerge, but I do think they are jumping the gun a bit. After all, truth to be told, where did we get long haired chihuahuas, they didn't just magically appear, but were crossed to bring in that coat. And selective breeding led to the sizes in the poodles and other breeds like the dachsunds. It is possible they might could come up with something. Look at those munchkin (I think that's what they are called) cats with the short front legs, they selectively bred that defect into it's own breed. My! What determination that must have taken.
