Overview
The American Bulldog is a strong, athletic working breed developed on Southern farms as an all-purpose utility dog — catching livestock, guarding property, and controlling vermin. It is far more agile and leggy than the English Bulldog it descends from.
Confident and deeply loyal, it forms powerful bonds with its family and is naturally protective. It is energetic and driven, needing an experienced owner who provides training, exercise, and clear structure.
History
Descended from working bulldogs brought to North America by early settlers, the breed nearly vanished after World War II before being revived by dedicated breeders. It retained its farm-dog function as a catch dog, guardian, and companion.

Temperament
The American Bulldog is affectionate and devoted with family, brave, and assertive. Its strength and guarding instinct call for thorough early socialization and consistent, positive training to produce a stable, well-mannered adult.
Health to watch
Joint malformation is common in heavy, active breeds. Screening and lean weight reduce arthritis risk.
Inherited skin (ichthyosis) and neurological (neuronal ceroid lipofuscinosis) disorders occur; DNA testing screens for them.
The breed's power and drive place stress on the knees, making cruciate tears a notable risk.
General breed tendencies, not a diagnosis. Every dog is an individual — pair this with regular veterinary care.
Care essentials
Vigorous daily activity and training channel this breed's strength and drive into good behavior.
Early, broad exposure ensures the guarding instinct is balanced and reliable around people and animals.
The short coat needs only weekly brushing; check skin folds and ears to prevent irritation.
