What does AJC before a name in dog show mean?

"AJC" before a dog's name in a dog show stands for "American Kennel Club". It means that the dog is registered with the American Kennel Club, the largest purebred dog registry in the United States.

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.
