This designation is important because it verifies that the dog is:
* Purebred: The dog's parents are both registered with the AKC and meet the breed standard.
* Eligible to compete: Only AKC-registered dogs are eligible to participate in AKC dog shows and other events.
So, seeing "AJC" before a dog's name tells you that the dog is a purebred and has the necessary registration to compete in AKC events.
