Jolly Rogers,
Unfortunately, it's too late to register for the AKC. But there is good news, you can register your dog at the CKC (Canadian Kennel Club). I believe (at least it used to be) all you have to have is two signatures (one professional) stating that the dog is purebreed, then you are set. You can check out their website at:
