History

 

There are many different theories about how the American Bulldog originated. In the olden days in England, people kept a bulldog which had a slim build and a mediocre snout. After more than a century these dogs change compared to the original "bullbiter" which thanks its name to a bloody sport in which a bull and dog do battle.
  Around 1900 people crossed the bulldog with a gentler breed of dog, this was to breed a dog which was more suitable for the family. They weren't used for biting but for defending the property. They looked like boxers with a tail, they were a lot healthier and could live to be up to 15 years old.
But how did the bulldog get to be known as the American Bulldog? It happend as follows... In the 1700's there was lot of criminality in England because the economy was bad. The prisons were filled with people who couldn't pay their debts. They got the choice of staying in prison and sitting out their sentance or to leave the country and go to the new colony of Georgia. This land had been conquered from the Indians. But none of the convicts chose for freedom in the new country, so people from the lower working class which couldn't survive in England left for Georgia to start a new life there.
They took all their possesions with them so this means they also brought their dogs with them. The dogs protected them from Indians and other dangers. As time passed a lot of dog shows were held in America, the American Kennel Club was founded and the frontiers dogs were called by different names. The show type bulldog, the old time bulldog, the working bulldog, the pit bulldog, the southern white, the old fashioned white and Georgia Giants. These are now all called by one name: the American Bulldog.
So read some books and investigate for yourself. Compare the different theories.
