National Kennel ClubSince 1964 the National Kennel Club (NKC) has operated to help dog owners register any purebred dog. This means for the next generation, they can be registered in the AKC also because it is guaranteed that they are purebreds with their parents. What's the difference between these two kennel clubs for breeding? I payed a lot of money for a NKC registered French Bulldog. No - NKC is another scam registry used by those who have such low quality dogs they cannot register with AKC. NKC is a registry set up by the puppy mills to get around the AKC rules and regulations that hampered indiscriminate breeding by puppy mills.
