Title: American Bulldog
Content:  The American Bulldog is a large breed of utility dog descended from the Old English Bulldog. They are now used on animal farms, dog sports, and for showing. They are part of American culture and history, and may be used as a cultural icon for the United States. They are generally represented as being strong and tough. In November 2019, the American Bulldog was added to the American Kennel Club (AKC) Foundation Stock Service (FSS).

Bull-baiting was also a common blood sport of the era and though there is evidence of such migrating to America with the landrace bulldogs brought by working class Englishmen in colonial times, it is also certain that the strains that migrated to America were unaffected by the banning of the sport in 1835 in the U.K. and, therefore, there was no need for a decline in the population of the old-type bulldog. In America, there are no records but rather acknowledged landrace strains that initially depended on where a dog's master originated in England, the majority of which were bred to work as 
Title: American Bully
Content:  Olde English Bulldogge in order to fine-tune desired physical characteristics and personality traits. The breed was first recognized by its breed club, the American Bully Kennel Club (ABKC), in 2004. This registry first acted as a means to document pedigrees and show the breed against its written standard. According to the ABKC the initial desire for this breed was to produce a dog with a lower prey drive and more of the "bully" traits and characteristics than the American Staffordshire Terrier. Mass and heavy bone was prioritized to ensure such a look, and due to this many of the dogs shown today display the wide front for which they were originally bred. The breed's development and popularity are commonly tied to the growth of hip-hop culture. The American Bully should not be confused with the several other bulldog-type breeds.

Later, in states like Texas, several separate strains of the "bulldog"-type dogs were kept by ranchers as utilitarian working dogs. Other dogs in time became guard dogs on plantations. Perhaps the most important role of the American Bulldog and the reason for its survival, and in fact why it thrived throughout the South, was because of the presence of feral pigs, introduced to the New World and without predators. The bulldogs were the settlers' only means of sufficiently dealing with the vermin. By World

American Bulldogs are now safe from extinction and their popularity has increased in their homeland, either as a working/protector dog, as a family pet, or both. All over the world, they are used variously as "hog dogs" (catching escaped pigs or hunting razorbacks), as cattle drovers, and as working or sport K-9s. American Bulldogs also successfully compete in several dog sports such as dog obedience, Schutzhund, French Ring, Mondioring, Iron Dog competition and weight pulling. They are also exhibited in conformation shows in the UKC, NKC, ABA, ABRA, ORKC, EKC. The AKC added the American Bulldog to the FSS on November 11, 2019.

Content:  II, the breed was near extinction until John D. Johnson scoured the back roads of the South looking for the best specimens to revive the breed. During this time, a young Alan Scott grew an interest in Johnson's dogs and began to work with him on the revitalization process. At some point, Scott began infusing non-Johnson catch bulldogs from working Southern farms with Johnson's lines, creating what is now known as the Standard type American Bulldog, also called the Scott type. At another point, Johnson began crossing his original lines with an atavistic English bulldog from the North that had maintained its genetic athletic vigor, creating the Bully type American Bulldog, also 
Title: Bulldog
Content:  The Bulldog, also known as the English Bulldog or British Bulldog, is a medium-sized dog breed. It is a muscular, hefty dog with a wrinkled face and a distinctive pushed-in nose. The Kennel Club (UK), the American Kennel Club (US), and the United Kennel Club (US) oversee breeding records. Bulldogs are popular pets; they were the fifth most popular purebreed in the US in 2017 according to the American Kennel Club. Bulldogs have a longstanding association with British culture, as the BBC wrote: "to many the Bulldog is a national icon, symbolising pluck and determination." During World War II, Bulldogs were often likened to Prime Minister Winston Churchill and his defiance of Nazi Germany. The Bulldog Club (England) was formed in 1878, and the Bulldog Club of America was formed in 1890.
Title: American Bulldog
Content:  The Old English Bulldog was preserved by working class immigrants who brought their working dogs with them to the American South; these dogs are believed to have first appeared as early as the 17th century. Small farmers and ranchers used this all-around working dog for many tasks including farm guardians, stock dogs and catch dogs. These dogs were not an actual breed as considered by today's standards and neither were most other dogs: kennel clubs of any kind did not yet exist and would not until 1875, at least two centuries after the Old English Bulldog first migrated to America. In the 17th and 18th century, the Old English Bulldog had many

Around the same time, many lower-class Irish and Englishmen were emigrating to America with their terrier–bulldog crossbreeds, including from both of those developing bloodlines. Over time, the descendants of these dogs became taller and heavier. Their masters opted for a dog that was both an aggressive warrior in the gambling dens of the cities and saloons but also was a working dog, its terrier and bulldog blood from Ireland and the UK proving to be very useful in farm work and in hunting. The breed was officially recognized as the American Pit Bull Terrier in 1898 and later its close kin the American Staffordshire Terrier in 1936.
Title: American Bully
Content:  The American Bully, as it is now known, began development in the 1980s with the majority of the final behavioral and aesthetic product being completed in the 1990s. There is consensus that at least five other breeds were used to attain the more "bully" physical traits desired as well as the more diminutive size of some lines. The American Pit Bull Terrier (APBT) was the foundation (parent breed) used to create the American Bully. The APBT has maintained a characteristic appearance and temperament for over a century. Within that span of time different strains of APBT emerged within the breed, each with different physical attributes. One particular APBT strain developed a specific, stockier, physique that warranted recognition as a different breed altogether. The bloodline of this APBT strain was then influenced with the introduction of American Bulldog, English Bulldog,
