STANDARD

Per Dr. Martines  notes

• 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 26-1/2 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.
