To drag this thread away from the vegans...
I have mixed feelings about the Kennel Club (and Crufts).
When you judge a dog in the show ring, aside from it being temperamentally stable enough to cope being in the ring, not bite the judge etc, you're not seeing anything about its mind. You're not seeing its working ability. You're not seeing how drivey it is, how good it is at working the wind, or working stock, whether it really would bring down a wolf, whether it's hardy enough to handle the weather that would be thrown at it, whether its coat would shrug off the rain, whether its conformation is robust enough to do a day's work. Nothing about trainable it is.
I don't know when there was last a dual champion cocker or Labrador: springer, cocker and labs have split into very different show and working types. I own a hunt-point-retrieve breed, and I know several dogs who both work and do well in shows, but even in those breeds a split is developing - some lines are losing their working ability, because if you don't breed for the working traits you will slowly lose them, and if you select against them (because a less driven dog is much easier to keep and handle) you will lose them even faster.
So, to that extent, the KC and Crufts destroy working breeds. And they also encourage - via what is rewarded in the show ring - the deformity of some breeds: the too-long dachshunds prone to back issues, the saggy-eyed bloodhounds that wouldn't last 5 minutes in the field, the brachy dogs that can barely breathe.
On the other hand, the KC maintains a registry, so you can know, if you're looking to breed a litter, that this stud dog is too closely related for comfort and that stud dog is far enough away. You can look at generations of health test results. All of that is valuable.
I'd love the registry system with the health test information without a show ring rewarding only looks.
