How interesting. It isn't something I see so much in Cardigan Corgis, but my guess is this is because there are not very many of them around.
I suppose a bit of the problem is also what pet homes want. No breeder is going to breed a litter of puppies and come out with more than a few (if they're lucky) that are show quality, which means the rest need to go to homes as pets. Border collies especially are ones that would be difficult to have in a normal home since ones bred from great herding lines would be ones that could be annoying to have around since their instincts would be so strong and they would have a deep need to work. So dumbing down a "show line" to make the "pet quality" puppies easier keepers would be to the pet homes benefit.
Here is an interesting article about Puggles (pug beagle mixes): Puggle | Embrace Breed Library
One of the main pieces I find interesting in it is how they talk about trying to find someone reputable who breeds Puggles. If there are people who breed mixes with the goal of creating a healthier breed (not just the cute factor), I wonder what the likelyhood of this working would be.
I know there are labradoodles that people are claiming are healthier than poodles and labs, but without actual health testing like the kind that purebred breeders do, you'll wind up with puppies that are still predisposed to blindness, hip dysplasia, and other illnesses from both breeds. The only reason not to do health testing and publish results, is if you're worried that something will come up or if you aren't willing to spend the money required to produce healthy puppies.
