Today, in the Home Depot parking lot, I saw an SUV with a human selling pups. The sign said "CKC Schnau-Tzu." Really? I wasn't aware the CKC was titling or granting pedigree status to cross breeds. First, I had not actually heard of a Schnau-Tzu until today, and second, what is the purpose? And how do you define a stable genetics base to provide for the health of future generations. You might have stopped some inbred recessives in this breeding but what about future breeding? Is there a wide enough gene pool of this mix to avoid drastic mutations? And, of course, a consciencious breeder puts more thought to this than selling next to the displayed camp houses in a Home Depot parking lot.
ETA:
I doubt the CKC referred to on the sign is the Canadian Kennel Club, as they are, by their website, promoting pure breeding.
The Continental Kennel Club site is down, so one cannot confirm the breeding practices and whether it extends to odd cross-breeding for the purpose of cosmetics or novelty.
ETA II:
Wikipedia has no reference or listing for the Continental Kennel Club. It's pretty bad when even Wikipedia hasn't heard of something, especially as it is a user defined encyclopedia.
