The oldest and most recognized purebred dog registries in North America are AKC (American Kennel Club) CKC (Canadian Kennel Club) and UKC (United Kennel Club). The UKC is a well-respected registry for many rare breeds as well as those recognized by the AKC. UKC is the second oldest registry, behind AKC. If your dog is registered with anything other than AKC, United Kennel Club or the Canadian Kennel Club, the chances of your pup being bred by an irresponsible breeder rises dramatically. |
