General Description : The Campeiro Bulldog is a medium-sized, short-haired breed with an imposing and well-balanced appearance. It is compact, robust, and strongly built, displaying both power and agility. The body is slightly rectangular in outline, with females typically being slightly longer than males. When viewed from above, the breed should be broad through the shoulders and taper to a comparatively narrower loin. The limbs are vigorous, muscular, and heavy-boned, supporting a sturdy frame. The head is large and substantial, paired with a broad, deep chest. The Campeiro Bulldog should never appear overly stocky or excessively heavy, nor should it be too light, lacking in substance, or loose in movement.

Head :  The head should be broad and substantial, with strong jaws, free of excessive wrinkles or loose skin. In females, the head may appear more refined and slightly less massive than in males. The skull is fairly broad and gently rounded. When viewed from the front while the dog is attentive, the top of the skull forms a straight line between the ears. The stop should be well defined. 

Ears : The ears are set high and spaced widely apart. They are small, pendant, and triangular in shape; rose ears (folded backwards) are also acceptable. When folded forward toward the eyes, the ear length should not extend beyond the inner corner of the eye.

Muzzle : Muzzle is short, measuring approximately one-quarter the length of the skull. It is broad beneath the eyes, with parallel side lines extending to the tip of the nose, and appears as square as possible when viewed from above. The lips are thick and pendulous but do not extend beyond the lower jawline by more than half the total height of the muzzle. The lip line should be as richly pigmented as possible. The jaws are broad, massive, and square. The lower jaw projects slightly beyond the upper jaw and curves gently upward at the tip, creating a mild to moderate undershot bite. Teeth are strong, with well-developed canines spaced adequately for gripping. Preference is given to incisors that align well with the canines. The bite should be as complete as possible. The cheeks are prominent, reflecting well-developed facial musculature.

Eyes : Eyes are oval and medium-sized, set neither too deep nor too prominent. Eyelids should be well pigmented, with preference given to lower eyelids that are in contact with the eyeball. Eye color ranges from black to dark brown or brown, with allowance for lighter shades in dogs exhibiting diluted coat colors.

Nose :  The nose is wide and well-pigmented, with large, open nostrils. Accepted pigmentation colors include black, blue, brown, red, and isabella.

Neck : The neck is strong, moderately long, and very muscular, with a circumference roughly equal to that of the skull. It has loose skin forming a dewlap, which should be present but not excessive.

Chest : Broad and deep, nearly round in shape, with depth reaching the level of the elbows.

Body : Withers should be clearly defined and prominent. Topline is firm and muscular and Back is moderately short and straight, with a gentle upward slope toward the croup. The loin is short, strong, and well-muscled.  Croup should be slightly rounded and ribs well sprung and well developed. The underline is slightly tucked up when viewed in profile

Shoulders : The shoulders are broad, muscular, and set at an oblique angle. They form approximately a 45° angle to the horizontal plane, with the scapulo-humeral (shoulder joint) angulation measuring just under 90°.

Legs : The forearms are broad and muscular. Elbows are strong and positioned slightly away from the ribs. The forearms are well-developed with strong, straight bones. The carpi (wrist joints) are straight, parallel, robust, and firm. Pasterns are slightly sloped when viewed in profile, strong, and well-boned; they should never appear weak or bent. The forelegs are set at right angles and run parallel to each other, following the line of the forearm. A slight outward turn is permissible.

Movement : The gait is balanced, with the head held in line with the back and the tail carried low, never rising above the level of the croup. The movement is characteristic of the breed, with visible balance through the croup and ribcage during motion. The hindquarters remain steady and level while walking.

Feet : The toes are slightly spread and gently arched, with thick, strong pads. Nails are strong and dark, matching the coat color, except where the corresponding toe is white, in which case white nails are acceptable.

Height : Ideal height for Males: 20 to 23 inches and Females: 19 to 22 inches at the withers. 

Weight : No exact weight is defined but the proportions of weight to height should reflect a vigorous, robust appearance. The dog should present a strong and solid overall impression. 

Color :  All colors are permitted except Merle.

Coat : The coat is short, smooth, and of medium texture—neither too soft nor too coarse to the touch. Skin is closely fitted to the body, with the exception of the dewlap under the neck.

Tail : The tail is naturally short and set low, thick at the base and tapering toward the tip. It is slightly curved rather than straight. Its length should not exceed two-thirds of the distance from the tail’s base to the hock. The tail is carried low during movement and never rises above the topline.

Temperament : The Campeiro Bulldog is a versatile breed with natural guardian instincts. It is known for its unwavering loyalty to its owner, along with its tenacity and courage. The temperament is calm, vigilant, and determined, reflecting a strong working drive. This breed makes an excellent family companion—highly docile with children and adaptable to various environments. It is confident yet controllable, without any signs of shyness. The Campeiro Bulldog is generally quiet, barks infrequently, and maintains a composed, even-tempered demeanor.
