IMHO, any breeder who gets upset over a registry question needs a little course in anger management
.
It was explained to me that the AKC has far more stringent policies for registration, up to and including "dropping in" to review records. AKC is basically only of any value if you are interested in showing, and the AKC can compel someone whose breeding stock has genetic problems to neuter the dogs to prevent future offspring. I'm sure it gets much deeper than that, but there it is in a nutshell.
I have no intention of getting into a show ring with my dogs. Nor is it my intention to breed them. In fact, my little girl's breeder won't send you the registry papers until you send her the bill from a vet setting forth the fact that the dogs have been neutered/spayed. At that point, what good are "papers" anyway?
I can understand a breeder jealously guarding the right to add "AKC Registered Puppies" in their adverts, but it actually doesn't amount to a hill of beans: there can be "sports" no matter what. It's like saying my puppies are Ferraris versus your silly little Porshe ...
Both my pups are CKC. I really don't care one way or the other. I fell in love with little bundles of fur; I saw their parents; I kinda know what to expect. I couldn't love them any more if their registration papers came diamond-studded. I gave up "name dropping/recognition" a long time ago. To some, it may be important - and more power to 'em. To me, it's not a big deal anymore.
