The American Bulldog is an athletic, temperamentally sound, medium to large size dog that possesses great strength, agility and confidence. The expression should reflect intelligence and alertness. The sturdy, powerful, yet compact frame is characteristically stockier and heavier boned in the males and more refined in the females. Some aloofness with strangers and assertiveness with other dogs is accepted.

**Note: The American Bulldog National Alliance judges are specifically charged with the responsibility of evaluating the temperamental stability as well as structural conformation on all dogs.

Any dog demonstrating shy or timid behavior, or that is out of control, presenting a danger to other dogs or people, will be dismissed from the ring at the judges discretion.

In officially recognizing two distinctive types of American Bulldogs, Standard and Bully, the ABNA requires that they be judged separately.

Size:

Males should range from 22-26 inches at the withers.

Females should range from 21-25 inches at the withers.

Standard: A leaner, more athletic dog in appearance.

Bully: A thicker, more powerful dog in appearance.

Weight should be in proportion to height in both types.

The dog should be well conditioned, not overweight or underweight.

One inch over or under the standard is a minor fault for both types.

Anything over one inch is a major fault for both types.

Color:

Solid white, white with varying degrees of brindle, brown, red, and tan is acceptable. Solid brindle, brown, red, or tan with no visible white is a cosmetic fault.

Solid black, blue, black and tan, tri color, and any degree of merle is a disqualification.

A full black mask is a major fault.

*Tri color is white with black and tan patches.

**Merle is a dilution of overall body color (black or red) with splotches of darker color giving the effect of "merling", or"marbling", not to be confused wit brindle, that gives the effect of "striping".

Coat:

Short, less than one inch in length, varying from soft to stiff.

Long, feathering, or fuzzy coats are a disqualification.

Head:

The head should be relatively large and broad in proportion to the size of the dog.

It should be flat on top giving a squared appearance.

There is a defined furrow between the eyes with a distinct, deep stop.

The head is well muscled throughout with prominent cheeks.

An excessively narrow head is a major fault in both types.

Standard: Generally box to wedge shaped in appearance, with a slightly shallower stop and less wrinkles.

Bully: Generally box to round shaped in appearance, with a more definitive stop and more wrinkles.

Eyes:

The eyes should be round or almond in shape, medium size, and wide set.

Dark brown is preferred, other colors are accepted, but are a cosmetic fault.

Black eye rim pigment is preferred, other colors are accepted, but are a cosmetic fault.

Crossed and/or nonsymmetrical eyes are a major fault.

Visible haw is a fault based on the severity.

Muzzle:

The muzzle should be relatively broad and square.

The jaws are well muscled, displaying great strength.

Lips are full, but not pendulous.

Black pigment on the lips is preferred, other colors are accepted, but are a cosmetic fault.

An excessively narrow muzzle is a major fault in both types.

Wry jaw is a disqualification in both types.

Standard: Muzzle should be 30% to 40% of the overall length of the head.

Bully: Muzzle should be 25% to 35% of the overall length of the head.

A muzzle longer or shorter than the standard is a minor fault.

Any breathing problems displayed in the ring will be considered a disqualification.

The dog may be dismissed from the ring at the judges discretion for the welfare of the dog.

Teeth:

The teeth should number 42 and be large in size.

Small and/or crooked teeth are a minor fault.

Missing teeth are a structural fault and will be penalized.

Working dogs will not be penalized for broken teeth.

Should medical removal of teeth be needed, documentation from a veterinarian is required.

Bite:

Standard: Reverse scissors is preferred.

A scissor bite or moderate underbite, up to 1/4 inch is acceptable.

Even bite is not preferred.

Bully: Undershot up to 1/4 inch is preferred.

Both Types: Anything over the accepted standard is a structural fault, and will be penalized based on the severity.

Teeth should not be visible when the mouth is closed.

Nose:

Black is the preferred color, with shades of red or brown being acceptable.

A lack of pigment is a cosmetic fault.

Ears:

The ears should be medium in size and may be either forward flap 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.

**In countries where it is illegal to crop the ears, owners must show a certification from a veterinarian for dogs that have been altered.

Neck:

The neck should be medium in length, muscular, slightly arched, and taper from shoulders to head.

Shoulders:

The shoulders should be well muscled with good definition and wide sloping blades giving the appearance of great strength.

** In countries where it is illegal to dock tails, owners must show a certification from a veterinarian for dogs that have been altered.

Feet:

The feet should be of moderate size.

The toes should be well arched and close together.

Crooked toes are a minor fault.

Splayed feet are a fault from minor to major, based on the severity.

Gait:

The American Bulldog should move smoothly with speed, power, and agility.

There should be no rolling or clumsiness.

The topline should remain level as the front legs are reaching, and the rear legs propel the dog forward.

As speed increases the feet move towards the center of the body for balance.

Dogs should not paddle, pace, or have a short stilted stride.

Any dog showing lameness will be dismissed from the ring for the welfare of the dog.

* Dogs with disqualifying faults will not be dismissed from the ring, but will not be considered for placement.

** Note: Males without two testicles, dogs that are deaf, and dogs that have been spayed or neutered are not allowed to compete in the conformation ring.

Females in heat are not to be shown in the conformation classes, and are not allowed in the proximity thereof.
