No, you can't breed a CKC to an AKC. They have to be the same registry. That's why my male is double registered... so I can stud him with either Pixie or Mylan. Pixie's pups will be registered CKC because she and Gizmo are CKC and Mylan's pups will be AKC because she and Gizmo are AKC. (Did that make sense...lol)
You can double register which ever pup is currently AKC. So if your female is AKC and you buy a CKC male, you can double register your female and her pups from the CKC male will be CKC registered. And vice versa, if your male is AKC and your female is CKC, you can double register your male (because he is already AKC) and the pups can then be registered CKC. You cannot, however, register a CKC pup with AKC.
Hope this helps..
