I don't know who told you this, but this is totally wrong.  There are many differences between the AKC and the CKC, but it has nothing to do with markings or if the dog meets a standard.  The AKC insists on proof that the dog is purebred and the breeder has breeding rights.  The CKC (Contenental Kennel Club) does not insist on any proof whatsoever, and you do not have to have breeding rights.  The CKC papers are worthless, it was started to mislead unsuspecting buyers because there is a reputable CKC, the Canadian Kennel Club.
