General History : Bulldogs in England were originally
working dogs who drove and caught cattle and guarded their masters'
property.
In old times they were used in brutal sport called bull baiting. One
of the excuses given for baiting was to tenderize the meat.
Notices of a bull-baiting were considered advertising for a fresh
meat sale, long before refrigeration made that commodity available.
Dogs were expected to fight until the bull submitted.They never walk
away from the fight against bull.
Later this sport become outlawed and this breed got replaced with
now called English Bulldog who are not as atheletic and strong as
American bulldog.
Because most northern tribes were nomadic, they could not have existed without their dogs to move their belongings from place to place.
The original "bulldog" was first brought to American shores
in early colonial times. American bulldog remains stronger in leg
than his counter part in england which went through breed improvement.
