american bulldogFollowing World War II, the American Bulldog was almost extinct.

Thanks to John D. Johnson from Summerville, Georgia the breed is still with us today. He gathered the best dogs he could find throughout the rural South and bred them back into popularity among his family and other rural families. His father bred the American Bulldog before John did and they have bred them longer than any other in any part of the world. His dogs were regularly used for tracking, hunting, guarding, watchdog and weight pulling. At some point Alan Scott joined Johnson breeding other bulldogs to Johnson's and forming the Standard American Bulldog.

The American Bulldog is popular today as a family pet and companion as well as a working dog.

american staffordshire terrierThe American Staffordshire Terrier is a part of all the confusion surrounding the group of “pit bulls”. The American Staffordshire Terrier is directly related to the English Bull Terrier and English Terrier. The breed of the English Staffordshire Terrier was bred in the early 19th century in the West Midlands. It was not until later that the breed came from Staffordshire. These English Staffordshire Terriers are also the source of contention by breeders who insist it was the Fox Terrier, White English Terrier, Tan and Black Terrier that are the ancestors of the English Staffordshire Terrier.

These terriers (AKA pit bull terrier) came to the United States in the mid 1800’s. By the late 1890’s they were accepted by the United Kennel Club (UKC)as the American Pit Bull Terrier – a new and distinct breed. There were also some that were accepted into the AKC as the Staffordshire Terrier. In England they were still known as the American Staffordshire Terrier. When the AKC accepted the breed in 1936 they were given a new standard, new purpose and new group – the terrier. In 1969 the American Kennel Club recognized these dogs as American Staffordshire Terriers and refused to recognize the American Pit Bull Terrier. The name was changed to move the breed away from its characterization as a bull fighter and to distinguish it from the smaller English Staffordshire Terrier. All American Staffordshire Terriers are directly related to the American Pit Bull Terriers.

american staffordshire terrier puppyThe American Staffordshire Terrier is a strong, powerful dog – stocky, muscular and graceful. At one point in time the American Staffordshire Terrier and the American Pit Bull Terrier were considered to be the same breed. Even today there are those that make that argument, but they have been recognized outside the AKC as separate breeds. The AKC only recognizes the American Staffordshire Terrier and not the APBT. However – even though there have been decades of separation in breeding the American Staffordshire Terrier and the American Pit Bull Terrier are the very same dogs genetically.

The American Staffordshire Terrier has a broad skull, high set ears and pronounced cheek bones. Their ears should not be cropped by AKC standards and their eyes are far apart, round and dark. With a medium sized muzzle and a heavy muscular back, they are as powerful as they look, if not more so. Most have black noses. The AmStaff has a broad, deep chest with wide set forelegs and compact feet. The tail is short and tapered and it should not be docked.

Health Problems

Hip Dysplasia

This is a serious issue in many breeds of dogs and is especially prevalent with the American Bull Dog. This may seem ironic in such a short legged dog but it is unfortunately very common.

The American Bulldog is prone to overeating and all the health issues that presents. With short legs and a genetic predisposition to arthritis and hip dysplasia, obesity is a real health risk for your bulldog.

Exercise and games

The American Staffordshire Terrier is an energetic, and athletic dog that loves to play and needs plenty of exercise. This breed is oriented to people and should never be left alone in the yard all day as a way for her to exercise. She needs you to play with her.

They excel at search and rescue. These are competitive dogs that want nothing more then to please their people.


american bulldog dogsThe American Bulldog is characteristically loyal, brave and reliable. It is a friendly, gentle dog that truly loves children. There is not a hostile bone in his body despite his history and reputation for bull baiting. Though he is protective of its family and affectionate with most, he still needs a human companion who is strong willed and a genuine pack leader. Without this he might become aggressive around other dogs and pets. They are immensely self-confident and they do slobber and drool and will become excited and hard to handle without daily exercise of both their body and their minds.

american staffordshire terrier dogsThe American Staffordshire Terrier is a loving, gentle dog that wants nothing more than to be with and please his people. Contrary to his reputation as a “killer”, this dog is actually a lover. They are great with children and want to be a part of the family. They even think they are lap dogs, regardless of their size. They are never going to be aggressive toward people and even though they are not one-person dogs, they are loyal, and they are devoted to the family and the “leader of the pack”.

This breed can tell who is their friend and who is not. They are not aggressive, but they will protect their own. They are courageous, confident, attentive, bold and strong-willed. The AmStaff gets along with other dogs most of the time, but they will never back down from a challenge and should never be left unsupervised with another dog. They should not be loose in a neighborhood or at a dog park. No matter how much you trust your American Staffordshire Terrier they can be killers in any fight with another dog.

In addition to this you must socialize and train your AmStaff. You need to be the pack leader and be in control. The AmStaff wants to please you so for a strong leader they will respond positively to positive training. They are intelligent and pick up quickly on what you want them to do. However, they are incredibly strong physically so training them to heel and walk with you obediently is a must. A well trained and exercised American Staffordshire Terrier is a happy dog and a loyal family dog.
