In the United States, for a puppy to be officially recognized as a purebred dog, it must be registered with an accredited kennel club, most commonly the American Kennel Club (AKC). The AKC maintains pedigree records for over 200 recognized breeds and provides registration certificates that document a dog's lineage. Registration confirms that both of the puppy's parents were also registered purebred dogs of the same breed, creating a verifiable chain of lineage stretching back multiple generations.
To register a puppy, the breeder must first register the litter with the AKC after the puppies are born, providing documentation of both parents' registrations and confirming details such as date of birth, number of puppies, and color. Individual buyers then receive a registration application from the breeder, which they submit to the AKC along with the applicable fee. The AKC then issues an official registration certificate for the individual puppy under the owner's name.
It is important for prospective owners to understand that AKC registration confirms only the pedigree lineage of a dog and does not serve as any guarantee of health, temperament, or quality. A dog can be AKC registered and still come from a puppy mill or irresponsible breeding program. Registration is simply a documentation service. Health testing of parents for breed-specific conditions, the breeder's reputation, the conditions in which puppies are raised, and the transparency of the breeder about health challenges in their lines are far more meaningful indicators of a puppy's likely outcomes than the presence or absence of registration papers alone.
