Before I begin - I am not talking about the Canadian CKC registration, but Continental Kennel Club (CKC). If she has one that is AKC and another CKC and she breeds them - the litter can only be registered with CKC and that is after she registers the one that is AKC to CKC. This will make both CKC with one having a dual registration. I could be wrong, but what I know is that AKC will not easily or at all register a CKC dog/litter to get them registered AKC.
And if she wanted to show her dogs why would she register them with CKC (continental KC) since theyare not into showing/confirmation yet. It doesn't make sense. All mine are AKC.
