Historically the American Bulldog was bred to be a “farm utility dog”. They were used to farm work in the South/Southeastern sections of the USA to work wild boar and cattle. They were also very much a part of the family, and were instrumental in personal and property protection as well.
The American Bulldog is a well balanced, short-coated, muscular and athletic animal. American Bulldogs display great strength, endurance, and agility. Males are characteristically larger, heavier boned and more masculine than the females.
American Bulldogs should be alert, outgoing and confident. Aloofness with strangers is acceptable.
Some assertiveness toward other dogs is not considered a fault.
Faults: Overly aggressive or excessively shy.
Standard Type: Ideal standard males should measure between 23 to 27 inches at the withers and weigh from 75 to 95 pounds. Females; 21 to 25 inches, 60 to 85 pounds.
Bully Type: Ideal bully males should measure between 23 to 27 inches at the withers and weigh 90 to 115 pounds. Females; 22-26 inches 80 to 105 pounds.
Note: The overall proportion of the dog is of utmost importance when evaluating weight.
