(American Bulldog Registry & Archives)
The American Bulldog is an athletic, temperamentally sound and medium to
large sized dog that possesses great strength, agility and confidence.
The expression should reflect intelligence and alertness. The sturdy and
powerful yet compact frame is characteristically stockier and heavier boned
in the males and more refined in the females.
However, an American Bulldog should not be excessively timid, shy or aggressive
towards man and preferably not overly aggressive with other dogs. Due to
its distinctive physical and mental characteristics along with its natural
desire to be the total companion and working dog, an American Bulldog should
never be confused with uniquely different breeds such as the American Staffordshire
Terrier or the American Pit Bull Terrier.
In officially recognizing the two distinctive types of American Bulldogs,
