I left ICB because they used scientific and other data from others without giving credit or citation on top of other things such as fee-based classes. PDE is rough to handle as there are some who are loud, bored, and ruthless in their defense without an ounce of open-mindedness and who critique with serious bias. Vicious commentary is often the death of these FB groups.
IMO, Most of the kennel clubs are rooted very firmly in the time period from the mid to late 1800s (latter 19th century).
People who want to improve purebred dog breeds by showing them and breeding the winners are rooted in the hundred or so years before the 1960s. (Up to mid 20th century). This might be because so many gene pools were dried up during World War 2, making the idea of “purebred” more akin to “inbred” to those who understood pedigrees and the practical aspects of dog breeding.
The latter 1900s (late 20th century) saw breeders who returned to the pre-kennel-club days of outcrossing and back to improve their purebred breeds. This era pretty much ended with DNA testing for dogs, but some breeders wish to return to this method of curing genetic disease in their kennel, and many younger breeders would like to have this option too.
I assumed these “outcross & and back” breeders would have much in common with other people who favor outcrossing. But, alas, this is not to be. See, some breeders view there to be a huge uncrossable gap between wanting to crossbreed and back TO IMPROVE SHOW DOGS, vs wanting to phase out dog shows, and replace them with events like obedience, rally, dock Diving, tracking, carting, sledding, dancing (heeling to music), dog parking, rally, treiball, rally, ballsports, disc catching, etc – and using the label “purebred” for puppies whose 4 grandparents and both parent all have a degree (title) in the same event.
So, “breeds” would be listed like racial make-up as part of a puppy’s physical description, but with no requirement that dogs be either forbidden or required to bred only to dogs who resemble themselves. The spotlight would be on the number of degrees the dog has in events you want to enter into.
Apparently, this idea brings out hatred from both people who love “purebred only, not a drop of any other breed” as well as from people who love the idea of outcrossing BUT ONLY TO IMPROVE SHOW DOGS. If you want to hear this in action, go over to where breeders praise the boxer X corgi outcross to improve show dogs, and mention that the F1 generation turned out so cute, the hybrids should have their own stud book, and the stud book should be left open to all F1 boxer X corgi crosses.
