美国斗牛犬品种源于如今已灭绝的古老的英国斗牛犬。这些动物是美国文化和历史的一部分。它们可以用作美国的文化偶像。
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 should not until 1875, at least two centuries after the Old English Bulldog first migrated to America.
古老的英国斗牛犬在17世纪和18世纪有许多不同的养牛，养牛场，养殖狗和屠夫的狗的菌株。公牛诱饵也是那个时代的一种常见的血液运动，尽管有证据表明，这种迁移到美国的人是工人阶级英国人在殖民时期带来的斗牛犬。
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.
美国波士顿大学lldogs are generally represented as being strong and tough. This breed was added to the American Kennel Club (AKC) Foundation Stock Service in November 2019.[1]
