History
The breed was commercialized by the Lane family of Rebecca, Georgia, USA, out of stock that originated on the Paulk plantation near the town of Alapaha, in a sustained effort over many decades to preserve the "plantation dog" of south Georgia from extinction. Detractors say that the ABBB is identical to the American Bulldog and that nothing distinctive is found in the Otto. Alapaha owners appear to disagree and photos seem to indicate a fairly distinct type.

Some fighters took hold of the breed and trained several generations into the sport of dog fighting. The dogs required too much training to be worth readying for the fighting ring, and they didn't do well, so it was soon dumped as a fighting dog.

Health
This breed is susceptible to entropion, an inversion of the eyelids.
