American Bulldog Breed History

It is theorized that the American Bulldog probably descended from the Mastiff and the English Bulldog that exists today. This breed often participated in the bloody sport of bull-baiting. Farmers and ranchers used them as all-around working dogs for various tasks including guards and hunting other animals like bears, wild boar, raccoons and squirrels. This breed was preserved by working class immigrants who brought working dogs with them to the American South.

American Bulldogs almost became extinct during World War II. They were scoured in the back roads of the South, and they were bred and revived. Today, this breed is safe from extinction. They are healthily increasing in popularity, either as a working protector or family pet.

American Bulldog Variations

Though dog breeders have long debated the issue, in reality there are two distinct American Bulldog types: classic and standard. The classic variant is often referred to as the Johnson American Bulldog, and is named after John D. Johnson, a noted mid-twentieth century bulldog breeder. Johnson bullies are the larger of the two varieties, and can closely resemble an English Bulldog. The standard variety, meanwhile, is often called a Scott (after Allen Scott, another famous breeder and one of Johnson's contemporaries); Scott bullies are more athletic, and are closer in resemblance to Pit Bulls. Though other bloodlines exist including the Hines, Old Southern White, and Painter bulldogs, it's likely these sub-types were produced from either the classic or standard variants (or possibly both).

These various American Bulldog types all have short, smooth coats.

Some breeders offer American Bulldogs of unusual size. The XXL American Bulldog (biggest), for example, can reach 30 inches at the shoulder in height, and weigh up to 150 pounds; Miniature American Bulldogs, meanwhile, can weigh as few as 40 pounds. It's likely these odd-sized variants are one of the above-named types, or hybrids produced by crossbreeding with another breed entirely. You may also see these variants offered as big, huge or giant bully type dogs.

American Bulldog Maintenance

Moderate maintenance is needed when raising American Bulldogs. Because they shed their short coat all year round, frequent brushing is required. Lack of grooming can lead to problems. Also, heavy exercise is needed. American Bulldogs need vigorous exercise, as they are known to be exuberant jumpers. They need plenty of space to run and jump. American Bulldogs seek constant attention and if it is not given may become destructive.

Grooming Requirements

American Bulldogs require some care and grooming, and baths are recommended only once every two months. This breed sheds its coat all year round, so frequent brushing is required. One thing to keep in mind are their ears. They need to get their ears cleaned on a regular basis to prevent them from catching yeast infection. Another area to watch out for is the mouth. Food can get trapped in the pockets of dogs with pendulum lips or tight faces, leading to tartar and tooth decay. It is important that their teeth are brushed often.

Exercise Requirements

American Bulldogs should be taken on long, daily walks. This breed is best owned by active people who are interested in developing their athletic abilities. Their athletic abilities include weight pulling, obedience, agility, hunting, and farm work. American Bulldogs need vigorous exercise to stay fit and happy. This breed is known for their rowdiness and exuberant jumping, especially when young. They should fit right in with an active family.

Living Requirements

This breed should be kept within a fence or on leash outside and trained through at least basic obedience because of their stereotypical behavior. They are large dogs that take up a lot of space in the car and in the home. They can be either outdoor or indoor dogs. This breed is okay in an apartment setting as long as they are given the adequate amount of exercise and activity. American Bulldogs need a home where there is plenty of outdoor activity. Though they can adapt sleeping both inside and outside, sleeping indoors is preferred.

Because they enjoy running and jumping through yards, they should not be kept confined in an apartment without daily walks and outside activity. They love surrounding themselves with family and crave constant attention, so they should never be left unsupervised for long periods of time. A lack of attention can lead to destructive habits.

American Bulldogs can sometimes become aggressive, so other pets living in the household are not recommended until the dog is well-socialized.

Temperature Range

Every dog is a potential victim of heat exhaustion, but the shorter breathing system of the American bulldog puts them as strong risk for heat stroke and heat exhaustion. It is best if the home this breed lives in is air-conditioned. They do not do well in warmer temperatures, and because of their thin coats, also do not do well in too cool of temperatures.

Random Details

Some interesting facts about the breed:

  • Lockjaw...or lock jaw? American Bulldogs--and any other breed, for that matter--cannot physically lock their jaws. "American Bulldog lock jaw" is actually a myth, in other words; these dogs do have incredibly powerful jaws (a bite strength of 305 PSI), but they can't lock them together. Lockjaw, meanwhile, is another name for tetanus, a medical condition that causes involuntary muscle contraction. One of its symptoms is the jaws being permanently clenched--hence the name.
  • American Bulldog vs. American Pit Bull Terrier: The AmBull and the Pit Bull are often confused as the same breed. In addition to being very similar to the Pit Bull in appearance and temperament, the AmBull was previously called the American Pit Bulldog--but in the late 20th century the "Pit" was dropped from the breed name to avoid further misunderstanding.
  • They're incredible jumpers: Due to their dense build, AmBulls have vertical leaps of 36 inches or more.
  • They're also fearless pig hunters: One reason these dogs became popular in the American South is because of their ability to chase and kill feral hogs, which would feast on farmers' crops. The AmBulls could catch a hog and tear out its throat with one powerful bite.

These dogs have an average lifespan of 10 to 16 years. Health problems can be found within certain genetic lines and are not common to the entire breed.
