Written by Dr. Antonio Nores Martinez


Solid, convex from back to front and transversely due to the relief of the mastication muscles and the nape.


Same lengh of the skull.

We have separated skull and face, however both form the "Head" of the Dogo, which is typical and, as explained in this work, is of the mesocephalic type and must have a convex-concave profile, that is, a convex skull due to the relief of the insertion of the masticating muscles, typical in prey dogs, of the "masticating' type, and the face and snout slightly concave upwards, typical of dogs with good olfaction. that is, having a skull for mastication and a face for olfaction as long as it implies a functional interaction: high sniffing.. zygomatic arches well separated from the skull, with an ample temporal cavity to comfortably insert the temporal muscle, one of the main masticators.)


Dark or nut-brown. With black or flesh colored eyelid rims, the separation between them must be large, vivacious and smart look and markedly stern at the same time. Light eyes or red brows are reasons to deduct points. Disparity of color is a reason for disqualification.)


Well matched, without prognathism, strong with large and well placed teeth. (The number of molars does not matter while the most important thing is the homogeneity of the dental arches, the lack of cavities, no upper or lower prognathism, and especially, that all four fangs, large and clean. match perfectly while pressing to seize the prey.)


Intensely pigmented in black, with a slight stop on Its tip, with ample nostrils. (A white nose or white stained nose deducts points. A divided nose or harelip are reasons for disqualification.)


On top of the head, erect or semi-erect. Of triangular shape, must always be cut. (The judge must not fudge a Dogo with long ears, and must remove it from the ring. Somewhat longer cut ears can be accepted in females like in Great Danes. The male is preferred with slightly shorter ears. The Dogo Argentino is a prey dog that is, a fighting dog, and long ears can be easily grabbed and very painful during fights Moreover, aesthetical reasons make it necessary to cut the ears.)


Must be well turned upwards, stretched, with free rims and pigmented in black. (Lips must be short for the dog to be able to breath through the side lip commissure while seizing the prey. If the lip is pendant, even if the maxillary is long, it works as a valve during inhalation, closing the lip commissure which impedes the animal to perform supplemental respiration though the lip commissures during the seize, having to release due to asphyxia. as it happens with breeds with hanging lips.)


Must not show any relief since it is completely concealed by the powerful muscles of the nape, forming an arch-shaped linkage between the head and the neck. (It is concealed by the curved line of the convexity of the skull.)


Thick, arched, well built, with a very thick skin by the throat, forming the wrinkles like those of the Mastiff, the Dogue de Bordeaux, the Bulldog, and not stretched, like in the Bullterrier. (Such elasticity of the neck skin is due to the cellular tissue being very slack in this region, allowing the neck skin to slide over the superficial aponeurosis, such that the fang or the paw of the contender only hurts the skin. In the case of a cougar, for example, which will try to seize it by the neck, since the skin is elastic and stretches a lot, it allows to seize the prey as well.)


Ample, deep. giving the sensation of having a large lung. When seen from the front, the breastbone must overpass the elbows. (Being the Dogo Argentlno, a dog for work and for fight, it is obvious the importance of an ample and deep chest due to the importance of breathing for the dog.)


Tall. Very strong. With large muscular relief's.


Ample; when seen sideways, its lower edge overpasses the elbows.


on the back, inclined toward the croup in a smooth slope. (In adult animals, when the development of back muscles and the kidney is adequate, when seen sideways they show a median channel along the spinal muscles.)


Straight, well set, with short and closed toes. The length of the toes must keep proportion with the foot and have fleshy pads, with thick skin and very rough, with callousness and allow the animal to run a lot through rough and stony terrain, without hurting.)


Concealed by the muscles in the dorsum.


Good muscles in the thighs, with short nails and tightly closed toes, with no dew claws. Must show good angulation, always having in mind that they are the drivers for speed and the support for close fighting so that the thigh muscle must always be emphasized. The dew claw, though very easy to get rid of during the first few months, is a reason to deduct points by being a recessive feature toward the Great Pyrenees, but is not a reason for disqualification.)


Long and thick, held hanging naturally, but without overpassing the hocks. It must be kept raised during the fight, with a continuous lateral motion, like when fawning with the master. (It must be kept in mind that the tail is very helpful, whether acting as a helm to change course during runs, as a compensatory support during the fight acting in combination with the rear quarters.)


40 to 45 kilos


60 to 65 centimeters. (With both the height and the weight, the judge must be inflexible, since being the Dogo a fighting dog among big game breeds, a smaller size decreases its efficiency.. Any adult Dogo, male or female, must be disqualified if less then 60 centimeters tall. Among many good candidates, the tallest must be preferred. The developer of this breed has expressed that the Dogo Argentino is a norm type, that is, it must keep harmonious proportions, or organic eurythmy, which translates into a larger force capacity. This is why the selected specimen must be that with larger height and weight, without being gigantic.)


Completely white. Spots of any color are a disqualifier due to its atavistic nature. White specimens with skin heavily pigmented in black must be deemed as not good for breeding, due to the recessive nature that represents, which can turn predominant in its descendants when mated with other specimens having this latent defect. Small spot on the head are not a reason for disqualification, however, between two similar specimens, the completely white must be preferred. On the other hand, any spot on the body is a reason for disqualification.)


Blue, light blue or eyes of inappropriate color, deafness, body spots, long hair, white or heavily white stained nose, prognathism (whether lower or upper). pendent lip, hound-like head, long ears (with no cutting). size shorter than 60 centimeters, more than one spot an the face and any physical disproportion. The dew claw deducts points, but does not disqualify it.

FCI Official Standard

ORIGIN : Argentina.


UTILIZATION : Big-game hunting dog.

CLASSIFICATION F.C.I. : Group 2 Schnauzer and Pinscher, Molossians and Swiss Mountain- and Cattledogs.

Section 2.1 Molossian type, Mastiff type.

Without working trial.

BRIEF HISTORICAL SUMMARY : This breed has its origin in the province of Cordoba, in the central (Mediterranean) region of the Republic of Argentina.

Its creator was Dr. Antonio Nores Martinez, a (renowned) doctor and member of a traditional local family. In 1928, his passion for dogs, perhaps a family legacy, led him to set the bases and a standard for a new dog breed which he named : Dogo Argentino. His work was based upon the methodical crossbreeding of several pure breeds with the old fighting dog from Cordoba , a dog which was very strong and vigorous but lacked psychic and genetic stability. This local breed had been the product of the crossbreeding among Mastiffs, Bulldogs and Bull Terriers and was widely known and appreciated by fervent dog-fight fans, a very popular activity at the time which embraced all social classes.

After a thorough and minute character study and selection, through different generations, Dr. Nores Martinez accomplished his purpose, obtaining the first family . At the beginning it was generally considered a dog for fighting but Dr. Nores Martinezfs liking for hunting led him to take the dog to one of his habitual hunting trips, where the new breed demonstrated its skills, thus becoming a key figure in all his trips. Thus it became quickly an excellent big-game hunting dog .

With the passing of time, this adaptating capacity has made this dog very versatile as regards functions; it has proved to be a noble companion and a loyal and insurmountable protector of those it loves. Its strength, tenacity, sharp sense of smell and bravery make it the best dog among those used for hunting wild boars, peccaries, pumas and other country predators which can be found in the vast and heterogeneous areas of the Argentinean territory. Its harmony, balance and its excellent athletic muscles are ideal characteristics for enduring long trips in any weather conditions and then fighting fiercely with the pursued prey.

On May 21st 1964, this breed was acknowledged by the Federacion Cinologica Argentina and by the Argentinean Rural Society, which opened their studbook to initiate registry.

It was not until July 31st 1973 that the breed was accepted by the Federation Cynologique Internationale as the first and only Argentinean breed, thanks to the great passion, work and effort of Dr. Augustin Nores Martinez, its creatorfs brother and successor.

GENERAL APPEARANCE : Molossian normal type, mesomorphic and macrothalic, within the desirable proportions 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 through 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, of a striking whiteness, its physical virtues turn it into a real athlete.

IMPORTANT PROPORTIONS : 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 equal to 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%.

BEHAVIOUR AND TEMPERAMENT : 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 domineering attitude makes it continuously compete for territory with specimens of the same sex, most noticeable behaviour in males. As a hunter, it is smart, silent, courageous and brave.

HEAD : Of mesocephalic type, it looks strong and powerful, without abrupt angles or distinct chiselling. 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 joins the neck forming a strong muscular arch.


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 muscle. 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 superciliary 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 Argentinean Dogo.

Lips : Moderately thick, short and tight. With free edges, preferably with black pigmentation.

Jaws/Teeth : Jaws strong and well adapted; no under-or overshot mouth. The jaws should be slightly and homogeneously convergent. They ensure maximum bite capacity. Teeth big, well developed, firmly implanted in line, looking clean without caries. 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 chiselling, covered by strong skin.

Eyes : Dark or hazel coloured, protected by lids preferably with black pigmentation though the lack of pigmentation 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 and with a length which does not exceed 50% of the front edge of the auricle of the natural ear. Without being cropped, they are of 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 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 prominences in this part, and fits to the thorax in a large base. It is covered by a thick and elastic skin that freely slips over the subcutaneous tissue which is a bit laxer than on the rest of the body. It has non-pendent smooth folds at the height of the throat, a fundamental trait for the function of the animal. The coat in 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; 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 to 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 fully developed dorsal and spinal muscles.

Croup : Of medium length, large and muscular; slightly showing the tips of both ilium and ischium. Its width is equal or a bit less than that of the thorax; the angle to the horizontal is of about 30, 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 45 angle to the upper line. Sabre- 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 sidewards. When trotting, it is carried level with the upper line or slightly above.


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, seen from the front or in profile.

Shoulders : High and proportioned. Very strong, with great muscular contours without exaggeration. Slanting of 45 to the horizontal.

Upper arm : Of medium length, proportionate to the whole. Strong and very muscular, with an 45 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 joint : Broad and in line with the forearm, without bony prominences or skin folds.

Pastern : Slightly flat, well boned, slanting of 70 to 75 to the horizontal plane.

Front feet : Rounded; with short, sturdy, very tight toes. Fleshy, hard pads, covered by black and rough-to-the-touch skin.

HINDQUARTERS : With medium angulation. As a whole, they are strong, sturdy and parallel, creating the image of the great power their function requires. They ensure the proper impulsion and determine the dogfs characteristic gait.

Upper thigh : Length proportionate to the whole. Strong and with fully developed and visible muscles. Coxo-femoral angle close to 100 .

Stifles : Set in the same axis as the limb. Femoral-tibial angle close to 110 .

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 propelling of the hind limb. Sturdy hock joint with a noticeable calcaneus (tip of hock). The angle at the hock joint is close to 140. Sturdy hock, almost cylindrical and at 90 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.

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

SKIN : Homogeneous, slightly thick, but smooth and elastic. Adhering to the body through a semilax 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, through this increases with the years. An excessive pigmentation of the skin is not accepted. Preference should be given to dogs with black pigmentation of the rims of labial and palpebral mucous membranes.


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 though 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.

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


Height at the withers : Dogs : 62 to 68 cm.

Bitches : 60 to 65 cm.

FAULTS : Any departure from the foregoing points should be considered a fault and the seriousness with which the fault should be regarded should be in exact proportion to its degree.


E Poor bone and muscle development (weakness).

E Nose with little pigmentation.

E Pendulous lips.

E Small, weak or decayed teeth. Incomplete dentition.

E Eyes excessively light; entropion, ectropion.

E Barrel chest; keel chest.
