BRIEF HISTORICAL SUMMARY: This breed is native to the province of Cordoba, in the Mediterranean region of Argentina. Its creator was Dr. Antonio Nores Martinez, a prominent and active surgeon (1907 – 1956).
His work was based upon the methodical crossbreeding of the “Old Fighting Dog of Cordoba”, a breed of great power and strength, which was the product of crossbreeding among dog of the breeds Bulldogs and Bull Terriers.
He selected completely white dogs for breeding, not undershot, with heavy heads and long muzzle.
After a thorough and minute character study and selection, through different generations, his aim was accomplished forming different families always using as a start the Old Fighting Dog of Cordoba which was crossed at first with English Bull Dog, Great Dane, Pyrenean Mastiff, Bull Terrier, Boxer, Pointer, Dogue de Bordeaux and Irish Wolfhound.
In 1947 the breed was already created and its genotype and phenotype were stabilized. The same year the breed standard was presented at the Hunter’s Club in the City of Buenos Aires.
Its strength, tenacity, sense of smell and bravery make it the best in the pack of dogs to hunt wild boars, peccaries, pumas and other predators of agriculture and livestock that inhabit the vast and diverse regions of Argentina. This is the traditional activity for which Antonio Nores created this breed.
In 1964 it was recognized as a breed by the FCA (Federación Cinologica Argentina) and the Sociedad Rural Argentina, which opened their studbook to initiate registry.
Just in 1973 the breed was accepted by the FCI. This was possible thanks to the great passion and unique work and effort of Dr. Agustín Nores Martínez, brother of the founder of the breed, who achieved this recognition not only because of his individual actions but also from the institutional action of the FCA and the Dogo Argentino Club “Dr. Antonio Nores Martinez”.
GENERAL APPEARANCE: It is an athletic dog, mesomorphic, normal type, of harmonious proportions. With powerful muscles and agile, his appearance gives the impression of power, energy and strength, in contrast to its expression of friendship and gentleness. All-white; can have a single dark spot on the skull.
IMPORTANT PROPORTIONS: Mesocephalic, the muzzle should be the same length as the skull.
The height at the withers should be slightly greater than the height at the croup.
Depth of chest should represent at least 50% of the height at the withers.
The length of the body should exceed the height at the withers by only 10% (maximum).
BEHAVIOUR AND TEMPERAMENT: It should be silent, never barking on the trail, with a keen nose and excellent flair, vent, agile, strong, robust and especially brave.
Should never be aggressive toward humans, a feature that will be severely observed. It must give you love without conditions or reservations.
HEAD: Of mesocephalic type, it looks strong and powerful. The cranio-facial axes are convergent.
Skull: Compact, convex seen in profile and from the front due to the outline of the well developed masticatory and neck muscles.
Occiput: Occipital protuberance not visible due to powerful muscles of neck which hide it completely.
Stop: Defined but should not be deep or have sharp/abrupt angles.
FACIAL REGION: As long as the skull, the line joining the two frontal orbital muscles is equidistant from the occiput and the mandibular joint of the upper jaws.
Nose: Strongly Black pigmented. Nostrils well opened.
Muzzle: Same length as the skull, with concave top line.
Lips: Tight, free edges, black pigmented, never pendulous. Jaws/Teeth: Jaws correctly positioned, well-developed and strong, With no under or overshot, with healthy teeth, large and with normal implant. Full dentition is recommended. Scissor bite, pincer bite is accepted.
Cheeks: Large, marked, covered by strong skin, without folds. Well- developed masseter muscles.
Eyes: Medium size, almond shaped, dark or hazel coloured, lids preferably with black pigmentation. Sub-frontal position, wide apart, lively and intelligent expression but at the same time remarkably firm.
Ears: Set high, lateral, well apart due to the width of the skull. Functionally, they should be cropped and erect, in triangular shape and with a length that should not exceed 50% of the front edge of the auricle of the natural ear. Without being cropped, they are of medium length, broad, thick, flat and rounded at the tip.
Covered with smooth hair which is slightly shorter than on the rest of the body; they can have 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 carried semi-erect.
NECK: Thick, arched, the skin of the throat is very thick forming smooth folds without forming dewlap. The elasticity of the skin is due to the cellular tissue being very lax.
BODY: Rectangular. The length of the body (measured from the point of shoulder to point of buttock) may exceed the height at the withers by only 10%.
Top line: Higher at the withers, sloping gently to the croup. The adults have a median furrow along the spine caused by the prominence of the spinal muscles. See from the side should not have any depression.
Withers: Strong, well defined and high.
Back: Very strong, with muscles well defined.
Loins: Short, broad, very muscular.
Croup: Broad and strong. Moderately inclined.
Chest: Broad and deep. Seen from the front and profile, the sternum must reach down to the level of the elbows, thereby giving maximum breathing capacity. The thorax is long with ribs moderately curved. Underline and Belly: Rising slightly on the bottom line of the chest, never tucked up, strong and with good muscle tension.
TAIL: Long, not to exceed the hock joint, thick medium set. At rest it hangs down naturally, in action it is raised in an arc with an ample curve.
General appearance: Legs straight, vertical, with short and tight toes. Shoulders: Laid back, with great muscular development without exaggerations.
Upper arm: Same length as the shoulder; well inclined.
Elbows: Sturdy, covered with a thicker and more elastic skin, without folds or wrinkles. Naturally placed against the chest wall. Forearm: As long as the upper arm, perpendicular to the ground, straight with strong bone and muscles.
Pastern joint: Broad and in line with the forearm, without bony prominences or skin folds.
Pastern: Rather flat, well boned; seen from the side slightly inclined, without exaggeration.
Front feet: With short and tight-fitting toes. With strong thick and resistant pads, preferably black pigmented.
General appearance: Well muscled, with short pasterns and tight- fitting toes, without dewclaws. Moderate angulation.
Upper thigh: Well proportioned, with visible and well developed muscles.
Stifles: Well angulated.
Lower thigh: Slightly shorter than upper thigh, strong and muscular. Hock joint / Hock: The tarsus-metatarsus section is short, strong and firm, ensuring powerful propulsion of the hind limb. Tarsus is robust, with the point of the hock very prominent. Hocks are strong, almost cylindrical and vertical, without dewclaws.
Hind feet: Similar to forefeet, although somewhat smaller and slightly longer, maintaining the same characteristics.
GAIT / MOVEMENT: Agile and firm; with noticeable modification when showing interest in something, changing into an alert attitude and responding with quick reflexes, typical for this breed. Calm when walking; trot is extended, with good front suspension and powerful rear propulsion. At gallop, the dog shows all of its energy, fully displaying its power. The movement is agile and firm when walking, trotting or galloping. Should be harmonious and balanced showing a solid body construction. Ambling (pacing) is not accepted and is considered a serious fault.
SKIN: Homogeneous, thick but elastic. The semi-loose subcutaneous tissue is elastic, without wrinkling, except on the throat, where the subcutaneous tissue is more lax. Lips and eyelids pigmented in black are preferred. Black pigmented skin is not penalized.
Hair: Uniform, short, smooth, with an average length of 1.5 to 2 cm. Density and thickness vary according to climate.
Colour: Entirely white. Only one black or dark-coloured patch on the skull, but which can also be located on one ear or around one eye. The size of the spot must be in proportion to the size of the head, not exceeding 10% of the latter. Comparing two dogs of equal quality, the whiter should be preferred.
