American Bulldog

At a glance
The American Bulldog is a powerful, athletic working bulldog kept by small farmers and ranchers of the American South as an all-round farm guardian, stock dog and catch dog for feral pigs and cattle — a breed that survived on its usefulness rather than its looks. Loyal and self-confident, it is a substantial dog of 27–45 kg that the AKC lists in its Foundation Stock Service. Hip and joint problems are the main health concern the AKC names, and a heavy, muscular dog like this needs care in Hong Kong's hot, humid summers.

Health
This page is general information compiled from published sources. It is not veterinary, legal or purchase advice. Dogs vary within a breed — talk to a vet or a reputable breeder about the dog in front of you.
Health notes are not veterinary advice. Conditions listed are those reported for the breed, not a diagnosis of any dog. Always consult a veterinarian.
Hip dysplasia
Commonly reported in the breed; breeders screen hips by X-ray. Ask your vet about hip screening and about keeping your dog lean and fit.
Elbow dysplasia
Commonly reported in the breed; breeders screen elbows by X-ray. Ask your vet if you notice front-leg lameness, especially in a growing dog.
Behaviour
A farm utility dog
The AKC describes a descendant of the English Bulldog brought to America by immigrants and used by small farmers and ranchers for many tasks — farm guardian, stock dog and catch dog — that survived in the South largely because of its ability to bring down and catch feral pigs; it was called a bulldog not for a look but because it did real bulldog work. The AKC sums up its temperament as loyal and self-confident.
Quiet, self-possessed, reserved with strangers
On the AKC trait chart the American Bulldog is rated 1/5 for barking, 2/5 for openness to strangers and playfulness, 3/5 for affection with family, energy and compatibility with children and other dogs, and 4/5 for trainability — a quiet, steady dog rather than an exuberant one. As with any powerful guardian-type breed, early socialisation and consistent training are essential.
Training and barking
AKC trait chart: trainability 4/5, barking level 1/5. Individual dogs vary; early socialisation and reward-based training are recommended for every breed.
