what is the difference between [AKC] AND [CKC] for breeding dogs?

First, do you been Canadian Kennel Club, or Continental Kennel Club for CKC?

I, personally, don't care for AKC, but that's preferance. They are much better than continental kennel club. You can register ANY dog with Continental Kennel Club. They're just looking to make a buck without any concern for the dogs.
