Hi and Welcome to YT!!
CKC is the worst! From what I understand.. only needs 2 signatures stating the dog is purebred to register with them.. You've learned a lot already
I would be concerned too. Most using that registry has been suspended from AKC. Even if it wasn't her that was suspended, but who ever she purchased hers from. Be very leary! Talk to her Vet, get references, go see her in person, and check the AKC suspension list located on this site.
I do know some breeders in CA if you PM me we can visit.
