According to the first one, the American Bulldog was brought over to America by the colonists, where they were primarily used as farm guards, stock dogs gathering cattle and as pack dogs to hunt or tree bears. It is, according to this theory, the "original" English Bulldog which has survived unchanged in remote rural communities, just as it was when it
The advocates of the first theory believe the American Bulldog is the pure embodiment of the original English Bulldog as it looked when the early settlers from the British Isles and Europe came to America in the 17th and 18th centuries. This idea was popularized by a couple of breeders, probably as a marketing ploy to sell their dogs. Others have eagerly swallowed the story, enabling its passage from myth to modern legend to widely-perceived truth.
However, it seems highly unlikely that the original English bulldog could possibly have survived unchanged in America for hundreds of years; through the generations he would have been interbred and shaped by his environment and the needs of his masters. This theory does have a certain romantic attraction to it however, so it is easy to understand it’s continuing popularity.
The advocates of the second theory believe the American Bulldog was created from a blend of various types of dog, which of course is true for every breed. More important is to know what exactly where the foundation dogs of these breeding programs, hence, the third theory option.
