Los Polleo Dogo Argentino - Breed Standard

FCI-Standard # 292 / 29.01.1999 / GB
DOGO Argentino
ORIGIN: Argentina.
DATE OF PUBLICATION OF THE ORIGINAL VALID STANDARD: 29.01.1999

Normal molossian type; mesomorphic and macrotalic within the desirable proportions, and without gigantic dimensions. Its aspect is harmonic and vigorous due to its powerful muscles, which stand out under the consistent and elastic skin adhered to the body though a not very lax subcutaneous tissue. It walks quietly but firmly, showing its intelligence and quick responsiveness and revealing, by means of his movement, his permanent happy, natural disposition. Of a kind and loving nature, and of striking whiteness, its physical virtues turn it into a real athlete.

It is cheerful, frank, humble, friendly, and not a hard barker, always conscious of its power. It should never be aggressive; a trait that should be severely observed. Its dominant attitude makes it compete continuously for territory with specimens of the same sex; a most noticeable behavior in males. As a hunter, it is smart, silent, courageous and brave.

As a mesomorphic animal, no part stands out from the whole body, which is harmonic and balanced. Mesocephalic, its muzzle should be as long as its skull. The height at the withers is the same as the height at the croup. The depth of the thorax equals 50% of the height at the withers. The length of the body exceeds the height at the withers by 10%.

Head:
Of mesocephalic type, it looks strong and powerful, without abrupt angles or distinct chiseling. Its profile shows an upper line, which is concave - convex: Convex at the skull because of the prominence of its masticatory muscles and its nape, and slightly concave at the foreface, the head joining the neck and forming a strong muscular arch.
Cranial Region:
Skull: Compact, convex in the front to back and transverse direction. Its zygomatic arches are far apart from the skull, forming a large temporal cavity, which enables the large development of the temporal muscles. Its occipital bone is not very prominent due to the strong muscles of the nape. The central depression of the skull is slightly noticeable.
Stop: Slightly defined, as a transition from the convex skull region to the slightly concave foreface. From the side, it shows a definite profile due to the prominence of the supraorbitary ridges
Facial Region:
As long as the skull.
Nose: Ample nostrils. Black pigmentation. It is slightly elevated forwards, finishing off the concave profile of the muzzle. From the side, the front line is perpendicular and straight, coinciding with the maxillary edge or slightly projected forward.
Muzzle: Strong, a bit longer than deep, well developed in width, with sides slightly converging. The upper line is slightly concave, an almost exclusive trait of the Dogo Argentino.
Lips: Moderately thick, short and tight. Free edges, preferably with black pigmentation.
Jaws/Teeth: Strong and well adapted jaws; no under-or overshot mouth. The jaws should be slightly and homogeneously convergent. They ensure maximum bite capacity. Big teeth, well developed, firmly implanted in line, looking clean and without cavities. A complete dentition is recommended, priority being given to the homogeneous dental arches. Pincer bite, though scissor bite is accepted.
Cheeks: large and relatively flat, free from folds, bulges or chiseling, covered by strong skin. Eyes: Dark or hazel colored, protected by lids preferably with black pigmentation, though the lack of the latter is not considered a fault. Almond-shaped, set at medium height, the distance between them must be wide. As a whole, the expression should be alert and lively, but at the same time remarkably firm, particularly in males.
Ears: High and laterally inserted, set well apart due to the width of the skull. Functionally, they should be cropped and erect, in triangular shape with a length which does not exceed 50% of the front edge of the auricle of natural ear. Without being cropped, they are mid-length, broad, thick, flat and rounded at the tip. Covered with smooth hair, which is a bit shorter than on the rest of the body: they may show small spots, not to be penalized. In their natural position they hang down covering the back of the cheeks; when the dog is alert they may be half-erect.

Neck:
Of medium length, strong and erect, well muscled, with a slightly convex upper line. Truncated cone-shaped, it joins the head in a muscular arch which hides all bony prominence in this part, and fits to the thorax through a large base. It is covered by a thick and elastic shin that freely slips over the subcutaneous tissue, which is a bit laxer than on the rest of the body. It has non-pending, smooth folds at the height of the throat; a fundamental trait for the function of the animal. The coat on this part is slightly longer than on the rest of the body.

Body:
The length of the body (from the point of the shoulder to the point of the buttock) exceeds the height at the withers by 10%. Upper line: Level of the withers and the pin bones of the croup are at the same height, constituting the highest points. Withers: Large and high.
Back: Large and strong, with fully developed muscles forming a slight slope towards the loins.
Loins: Strong and hidden by the developed lumbar muscles, which form a median furrow along the spine. Slightly shorter than the dorsal region, rising very slightly till the top of the croup. The development of muscles in the parts of the upper line causes the dogs to show a slightly depressed profile without being actually so, which is enhanced in adults due to the full developed dorsal and spinal muscles.
Croup: Of medium length, large and muscular; slightly showing the tips of both ileum and ischium. Its width is equal or a bit less than that of the thorax; the angle to the horizontal is of about 30 degrees, thus the upper line falling in a slightly convex slope towards the insertion of the tail.
Chest: Broad and deep. The tip of the breastbone is level with the tip of the shoulder joint (scapulo-humeral joint) and the sternal line of the thorax is level with the elbow line. Large thorax providing maximum respiratory capacity, with long and moderately curved ribs, which join the breastbone at the height of the elbow line.
Abdomen: Slightly tucked up beyond the bottom line of the thorax, but never greyhound-like. Strong, with good muscular tension as well as in the flanks and loins.
Tail:
Set medium high, with a 45-degree angle to the upper line.
Saber-shaped, thick and long, reaching to the hocks but not further down. At rest it hangs down naturally; when the dog is in action it is slightly raised over the upper line and constantly moving sideward.
When trotting, it is carried level with the upper line or slightly above.

Gait / movement:
Agile and firm; with noticeable modification when showing interest in something, changing into an erect attitude and responding quickly to reflexes, typical for this breed. Calm walk, extended trot, with a good front suspension and a powerful rear propulsion. At gallop, the dog shows all its energy, displaying its full power. The four feet leave simple, parallel traces. Ambling (pacing) is not accepted and is considered a serious fault.

imbs:
Forequarters: As a whole, they form a sturdy and solid structure of bones and muscles, proportionate to the size of the animal. Forelegs straight and vertical, both seen from the front or from the side.
Shoulders: High and proportioned. Very strong; great muscular contours without exaggeration. Slanting of 45 degrees to the horizontal.
Upper arm: Of medium length, proportionate to the whole. Strong and very muscular, with a 45 degree angle to the horizontal.
Elbows: Sturdy, covered with a thicker and more elastic skin, without folds or wrinkles. Naturally situated against the chest wall of which they seem to be part.
Forearm: As long as the upper arm, perpendicular to the horizontal, straight with strong bone and muscles.
Pastern: Slightly flat, well boned, slanting of 70 to 75 degrees to the horizontal plane.
Front feet: Rounded; with short, sturdy, very tight toes. Fleshy, hard pads, covered by black and rough skin.
Hindquarters: With medium angulations. As a whole, they are strong, sturdy and parallel, creating the image of the great power that their function requires. They ensure the proper impulse and determine the dog's characteristic gait.
Upper thigh: Length proportionate to the whole. Strong and with fully developed, visible muscles. Co-femoral angle close to 100 degrees. Stifles: Set in the same axis as the limb. Femoro-tibial angle close to 110 degrees.
Lower thigh: Slightly shorter than the upper thigh, strong and with similarly developed muscles.
Hock joint/Hock: The tarsus-metatarsus section is short, strong and firm, ensuring powerful propulsion of the hind limb. Sturdy hock joint with a noticeable calcaneus (tip of hock). The angle to the hock joint is close to 140 degree. Sturdy hock, almost cylindrical and at a 90 degree angle to the horizontal. If present, dewclaws should be removed. Hind feet: Similar to forefeet, though slightly smaller and broader, but with the same characteristics.

Coat:
Hair: Uniform, short, plain and smooth to the touch, with an average length of 1.5 to 2 cm. Variable density and thickness according to different climates. In tropical climates the coat is sparse and thin (letting the skin shine through and making pigmented regions visible which is not a cause of penalty). In a cold climate it is thicker and denser and may present an undercoat.

Color: Completely white; only one black or dark colored patch around the eye may be admitted, providing that it does not cover more than 10% of the head. Between two dogs of equal confirmation, the judge should always choose the whiter one.

Skin:
Homogeneous, relatively thick, but smooth and elastic. Adhering to the body through a semi lax subcutaneous tissue, which ensures free movement without forming relevant folds, except for the neck area where the subcutaneous tissue is laxer. With as little pigmentation as possible, though this increases with the years. An excessive pigmentation of the rims of labial and eyelid mucous membranes

Faults:
Any departure from the foregoing points should be considered a fault and the seriousness of the fault should be in exact proportion to its degree.
Serious faults:
Poor bone and muscle development (weakness).
Nose with little pigmentation.
Pendulous lips.
Small, weak or decayed teeth. Incomplete dentition.
Light-colored eyes; entropion, extropion.
Barrel chest; keel chest.
Flat ribs.
Excessive hindquarters' angulations.
Too long hocks.
Untypical movement
Excessive skin pigmentation in young dogs.
Appearance of small areas with colored hairs.
Unsteady temperament.

Disqualifying faults:
Non-pigmented nose.
Over-or undershot mouth.
Light blue eyes; eyes of different color (heterochromia).
Long coat.
Patches on the body coat. More than one patch on the head.
Height under 60cm and over 68cm.
Aggressiveness.

SKULL. Solid, convex in the ante-posterior sense and transverse by the relieves of
the masticatory muscles and nape.
FACE. Of the same length as the skull, that is to say that the line which connects both orbitarian apophyses of the frontal bone are at the same distance from the occiput and the alveolar edge of the upper jaw bone.
EYES. Dark, wrapped up in the eyelids (of dark or light colored edges) the separation between them has to be big, it has to have a vivacious and intelligent look, but with a pronounced hardness at the same time.
JAWBONES. Well adapted, without prognathism, strong, with good dental implantation.
NOSE. Strongly pigmented in black, with a slight stop at the tip, wide nostrils.
EARS. At the top of the head, erect or semi-erect, triangular shaped, they always have to be cut off.
LIPS. Well rolled up, taut, free of black pigment lips.The short lip is required, so that when the dog is holding the catch, allows it to breath through the posterior corner of the mouth, because if the lip is "pendulum" although the jaw bone quite long, is somewhat a valve in the isnpiration and closes the corner of the mouth keeping the animal from making a suppletory breathing through mouth while holding the prey, forcing it to let the piece go due to asphyxia as it happens to the Mastif.
OCCIPUT. It must not make relief, because the potent muscles of the nape will erase it completely, being the insertion of the head and neck as an arch.
NECK. Thick, arched, slim, with a very thick throat skin, making wrinkles as in the Mastif but not so taut as those in the Bull-Terrier. This elasticity of the neck's skin is due to the cellular tissue of this part is very lax allowing the skin to slip over the superficial aponeurosis , in this way the adversary's fang or claw , only hurts the skin and if it were another dog which attempts to get hold of it neck, as the skin is very elastic and strectches a lot it lets it to hold the other dog at the same time it is beeing held.
HEIGHT. 60 to 65 cm. (23 to 26 inches)
WEIGHT. 40 to 45 kg. (88 to 100 Pounds)
CHEST. Wide and deep, with the sensation of having a great lung. Seen from the front the sternum or breast bone has to surpass below the elbows.
BACK. Height, very strong, with great muscular relieves.
THORAX. Wide, side view the lower edge passes the elbows.
COLUMN. Higher in the back, with a slight slope towards the haunch; in adult animals, when the muscular development of the back and kidneys is good, from the sideview it looks like an armchair and presents the medium channel all the length of the column, given by the relief of the spinal muscles.
HANDS. Rights, well planted, with short toes and well joined.
KIDNEY. Erased by the muscles of the back.
LEGS. Of muscular thighs, with a short heel and closed fingers, without aberrant fingers.
TAIL. Long, straightened in arch, with a wide curve upwards. During combat they keep it lifted and in constant side motion, as when the animal receives its master. The length must be shortened to improve harmony as a whole, for which preferential treatment should be given to those that have the tail reaching no farther than the heel.
MANTLE. Totally white, some dark or black stains can only be tolerated in the eyes or front edge of the ear , Any other stain in whichever part of the body it may be located might rule the animal out as a sign of atavic character. The white specimens with a very black pigmented skin, has to be considered as not fit for breeding due to the recessive character which is shown and that might become predominant in the offspring, if it mates with another specimen sharing the same potential defect.
MOTIVE FOR DISQUALIFICATION. Sarco eyes, deafness, stains in the body, long hair, white nose, prognathism, pendulum lip and any other body disproportion.
