Bj ranks 1846 in the pet registry with 54 male animals. This is almost certainly a data artifact — an abbreviation or initialism that got filed as a given name. BJ as a full name does exist (usually short for Billy Joe or Bobby Joe in the American South), but the lowercase filing here suggests transcription inconsistency rather than intentional naming.
The Initialism in the Registry
Pet licensing databases capture whatever the owner writes on the form, and abbreviated names are common at the lower ranks of the registry. BJ, RJ, TJ, and similar two-letter combos appear throughout. The name at face value is an initialism with real American-South roots: Billy Joe, Bobby Joe, Benjamin Jacob.

If You're Actually Naming a Pet BJ
BJ has a breezy, casual energy for a nickname-style name. It's short, easy to call, and carries a slight country-music association. Coonhounds and Beagles in Southern-style owner households are the natural fit for the full BJ tradition. The name projects friendliness without effort.
The Counter-Reading: Two Letters Aren't a Name
An initialism as a pet name works well in daily life but creates consistent friction in paperwork, vet records, and anywhere the name needs to be legible at a glance. The lowercase filing in the registry suggests this was often not the intended name at all — just a note that became official. Billy or Bobby would give you the same energy with more clarity.
