American bulldog

American Bulldogs are known to have friendly dispositions while displaying great strength and athleticism which is where they get their name.  Males weigh anywhere between 75-100 lbs., with an average height of 24 inches and females can typically weigh between 60-80 lbs. with an average height of 22 inches. American Bulldogs are often energetic, confident and friendly. These dogs do not do well in isolation and do best when given time and attention by their owners.  Socialization is important.
