Legitimate Dog Registration was created to maintain a registry for purebred dogs and preserve its integrity. To provide a non-bias but regulating means to ensure the pedigrees of purebred dogs.
Your puppy papers are a birth certificate, which must be issued by a proper authority in order to get your passport or Dog Registration.
Every Country issues it's own passport and every Country recognizes the "official" passport of other Countries.
In order to have AKC papers on your puppy it must be born in the United States or enter the US with papers (passport) from the correct foreign registry.
Now, being as Americans are well noted for their creativity in business we have many "Dog Registries", many of which are named very, very close to foreign legitimate registries. Creating confusion among the average dog owner.
The Canadian Kennel Club (CKC) is the official dog registration for Canada and they recognize AKC and AKC recognizes them. In order to have CKC papers your puppy must have been born in Canada. You can't have a CKC dog in America but if you buy a CKC dog from Canada, AKC will recognize it and register it.
In Louisiana there is a dog registry called the CKC, it is not the Canadian Kennel Club but the Continental Kennel Club. Although their website and "papers" are very pretty they are not a recognized by the AKC or other foreign registries. If you would like to register your dog with them you need NO documentation except a couple pictures and a witness. No birth certificate, No proof of parentage. They even so much as have a "standard" which states the "Neapolitan Mastiffs muzzle should taper" - a dobermans muzzle should taper, a Neapolitan Mastiffs muzzle should be square. How ridiculous would a Neo look with a muzzle that tapers!
Throughout the rest of the world The Fédération Cynologique Internationale (FCI) regulates Dog Registry. The FCI was created in 1911 and oversees over 80 countries. Including Italy, where our beloved Neapolitan Mastiff originated. Each country has ONE official registry, for Italy it is ENCI.
Now FIC is another business in Alabama, it is not the Federation Cynologique Internationale (FCI) but the Federation International Canines. Although their logos and initials are identical in content they are not related what so ever! The papers issued by the FIC are very official looking and easily confused with the real FCI documents. Again, you need nothing to "register" your dog with them, except a credit card. FIC registration papers are NOT recognized by the AKC or anyother foreign registry.
Basically each Country has ONE official Registry, if the dog is born in that country it gets the respective papers then when it moves to another Country it must get new papers from that Country's official registry. All Countries have agreements but only with the correct official registry.
