In the 1970s David Leavitt created a true - breeding lineage as a re-creation of the healthier working bulldog from early nineteenth century England . Using a breeding scheme developed for cattle, Leavitt crossed English bulldogs, American Bulldogs, American Pit Bull Terriers and Bull Mastiffs . The result was an athletic breed that looks similar to the bulldogs of 1820 but also has a friendly temperament . </P> <P> The Olde English Bulldogge was an attempt to recreate the "Regency Period Bull Baiter" and was developed in the early 1970s by David Leavitt, of Coatesville, PA . Leavitt began his project in 1971 utilizing the cattle line breeding scheme of Dr. Fechimer from Ohio State University . The goal was to create a dog with the look, health, and athleticism of the original bull - baiting dogs, but with a much less aggressive temperament . The foundation crosses consisted of 1⁄2 English Bulldog, and 1 / 6th American Bulldog, 1 / 6th American Pit Bull Terrier and 1 / 6th Bull Mastiff . After many planned crosses, the Olde English Bulldogge emerged and began to breed true . </P>
