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.
The Shih Tzu is an Imperial Chinese breed developed by palace breeders hundreds of years ago with breed stock from the Tibetan lines. It is quite probable that the Shih Tzu was originally a cross between two Sino-Tibetan ancient dogs – the Pekingese and the Lhasa Apso. Based on their looks, the Shih Tzu means the lion dog, but they were really very pampered palace dogs living with the Chinese emperors and families. The emperors were always gifting the breeders who developed the most affectionate, gentle and beautiful Shih Tzus.
Until the 1930’s the Shih Tzu was not known to the world outside the emperor’s palace. Once the breed did come out from behind the palace walls, they were immediately popular. Much debate went on about how to refine the breed as clubs began to spring up in Peking and then in England. It was not until 1969 the Shih Tzu was recognized and entered in the AKC Stud Book.
While the original Shih Tzu might have been a mix between the Pekingese and the Lhasa Apso, today’s breed spread around the world after the second world war. In Europe in the 1930’s the breed was classified as Apsos. In 1935 the first Shih Tzu Club of Europe was formed, and the first standard was written, and the breed was categorized as the Shih Tzu.
Following World War II, soldiers brought the dogs to the States from Europe. By the 1950’s the breed was growing in popularity and the AKC recognized the breed in 1969 as members of the Toy Group. They are now recognized by all major kennel clubs throughout the western world. They are recognized by the Federation Cynoloqique Internationale in the Companion and Toy Group, among Tibetan breeds.
The Shih Tzu is a good watchdog, but it was bred to be a companion animal. It is a friendly, open breed that welcomes strangers. They are great with other animals and children as well as adults.

This is a breed of lively, sturdy and alert little dogs with a beautiful double coat that is flowing and long. In its full glory the Shih Tzu coat is touching the floor all the way around the dog.

There are a few differences between the European or UK Kennel Club standard and the American Kennel Club AKC standard. As opposed to the UK standard the AKC standard states that:

The 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.
