Appearance

There are two distinct strains of American Bulldogs, Classic (Johnson,
Bully) and Standard (Scott, Performance) which is often mistaken for its
second cousin, the American Pit Bull Terrier because of its appearance,
and for its much smaller European relatives because of its name. The
American Bulldog is different from any of these. The American Bulldog is
massive in comparison.

Temperament

An American Bulldog is typically a happy, friendly, and assertive dog that
is at ease with its family and fine with strangers as they get to know the
stranger in question. They are quite fond of children but sometimes do
not know their own strength, thus, as with all dogs, they should be
supervised with small children. They bond strongly with their master and
family but, because of strong guarding instincts and a somewhat
dominant attitude, they need a firm but fair hand; they should be
socialized and obedience trained early to expose them to other dogs and
people.

History

The history of Mastiff-type dogs in the British Isles dates back beyond the
arrival of Caesar, who reported of the ferocious dogs. With the arrival of
the Normans in 1066 came Alaunts from the continent. The breeding of
the indigenous mastiffs to the newly arrived ones produced the Mastiff
and Bulldog of England.
