If you have a purebred Pit Bull that is currently unregistered, you can apply for a certificate of registration with one of several dog breed associations, including the American Dog Breed Association, the United Kennel Club and the American Pit Bull Registry. Each association has its own particular requirements, which the Pit Bull must adhere to in order to be registered. Obtaining a certificate of registration will give your dog a purebred status, which will increase the value of the dog and any puppies that result from breeding the dog with other purebred Pit Bulls.
Request a document that includes the information of your dog's family history before you purchase an alleged purebred Pit Bull to ensure that it is in fact a pure bred. You will need to prove that your Pit Bull has three generations of purebred Pit Bulls in its family history on both its mother's and father's side.
Evaluate your dog to determine which dog breed association you should register with. Check that your Pit Bull has a large head with a broad skull and round eyes, a thick, well-muscled neck, and a stocky, well-muscled frame with straight legs and a deep chest. Your Pit Bull must also have a short-haired coat. Check your Pit Bull's coat for any areas of merle colouration, as the American Pit Bull Registry will not accept a Pit Bull with this colouring. Check your Pit Bull's eyes, as the United Kennel Club will not register a Pit Bull with blue eyes. Both the United Kennel Club and the American Dog Breed Association will not register a Pit Bull with a docked tail, although all three dog associations will accept a Pit Bull with cropped ears. Your dog will be disqualified if it is blind, deaf, shy, aggressive or spayed neutered.
Contact the dog breed association that you have chosen to register with. Provide the required documentation that proves that your dog has a family history of purebred dogs. Fill out the required application form, and ask the breeder from which you purchased your Pit Bull to sign it to prove that the family history is legitimate. Send the application to the specified address, along with some photographs of your Pit Bull. The association will contact you to inform you of whether your dog is eligible for registry.
