Ears:  The ears should be medium in size, high set, and may be drop, semi-prick, or rose, with no preference.   Cropped ears are a cosmetic fault, due to the fact that they have been cosmetically altered and can not be judged in their natural state.

  Fault : Visible haw.  Disqualifying Fault : Crossed and/or nonsymmetrical eyes.

Nose:  Broad with open nostrils (nares) with no sign of air restriction.   The nose should be a solid color. Lacking pigment is a serious fault. A nose lacking all pigment is a disqualifying fault.

Neck too short and thick; thin or weak neck.

Chest:  The American Bulldog's chest is deep and moderately wide.  The ribs are well sprung from the spine and then flatten to form a deep body extending at least to the elbows, or lower in adult dogs.

Back:  The topline of the American Bulldog inclines very slightly downward from well-developed withers to a broad, muscular back.

The loin is short, broad, and slightly arched, blending into a moderately sloping croup.

The flank is moderately tucked up and firm.  Faults: Swayback; sloping topline.

Shoulders:  Shoulders should be well laid back with significant angulations to allow for good movement.  Straight shoulders are a fault.

Legs:  The front legs of the American Bulldog should be straight with moderate to heavy bone. Pasterns should be strong and upright.  Weak pasterns are a major fault.  

Elbows that are bowed or twisted are a fault from minor to a disqualification, based on severity.

 Pasterns should be strong and upright.  Weak pasterns are a major fault.

Feet:  The feet of the American Bulldog a round, tight both front and rear, and the pasterns should be strong.  Weak  pasterns and/or splayed feet are disqualifying faults. 

Height:  Desirable height in a mature male ranges from 22 to 27 inches; in a mature female, from 20 to 25 inches.

Weight:  Male American Bulldogs are typically larger with heavier bone and more muscle than female American Bulldogs. Both sexes, however, should have a well-balanced overall appearance.

Preferred weight in a mature male ranges from 75 to 125 pounds; in a mature female, from 60 to 100 pounds.

Color:  Any color, color pattern, or combination of colors is acceptable for the American Bulldog, except for merle, solid black, solid blue, and tricolor (white with patches of black and tan).

Some dark brindle coats may appear black unless examined in very bright light.

Disqualifying Fault:
Solid black or blue with no white markings; tricolor (white with patches of black and tan).

Coat: The coat is short.  A wavy coat or a long coat is a disqualifying fault.  There should be no signs of feathering on the legs or neck area, also a disqualifying fault.

Tail:  The American Bulldog may have a natural or a docked tail, but the natural tail is preferred. The natural tail is very thick at the base, and tapers to a point.  A "pump handle" tail is preferred but any tail carriage from upright, when the dog is excited, to relaxed between the hocks is acceptable.   The pump handle tail should be carried low and not over the back of the dog.  Serious fault: Tail curled over the back; corkscrew tail; upright tail when the dog is relaxed.

Temperament:  The disposition of the American Bulldog should be outgoing and happy.  While a watchful nature may be expected at home, human aggression without provocation is a disqualifying fault.
