Its direct ancestor is the "canis pugnax' (the old Roman Molossian) of which he is the light version employed in the hunting of large wild animals and also as an 'auxiliary warrior' in battles. For years he has been a precious companion of the Italic populations. Employed as property, cattle and personal guard dog and used for hunting purposes too. In the past this breed was common all over Italy as an ample iconography and historiography testify. In the recent past he has found a excellent preservation area in Southern Italy, especially in Puglia, Lucania and Sannio. His name derives from the Latin 'cohors' which means 'guardian', 'protector'.

General Appearance
Medium-big size dog, strongly built but elegant, with powerful and long muscles, very distinguished, he expresses strength, agility and endurance. The general conformation is that of a mesomorphic animal whose body is longer than the height at the withers, harmonious as regards the form and disharmonious as regards the profile.

Important proportions
The length of the body is about 11% over the height at the withers. The total length of the head reaches 3,6/10 of the height at the withers. The length of the muzzle is equal to 3,4/10 of the total length at the withers and it is equal to the height of the limb at the elbows.

Behaviour and temperament
Intelligent, active and even-minded, he is an unequalled watch and protection dog. Docile and affectionate with the owner, loving with children and with the family, if necessary he becomes a terrible and brave protector of people, house and property. He is easily trained. 

Head
Brachycephalic. Its total length reaches 3,6/10 of the height at the withers. The bizygomatic width, which is equal to the length of the skull, is more than half the total height of the head, reaching 6,6/10. The upper longitudinal axes of the skull and of the muzzle are slightly convergent. The perimeter of the head, measured at the cheek-bones, is more than twice the total length of the head even in the females. The head is moderately sculptured with zygomatic arches stretched outwards. The skin is firm and sticking to the tissues underneath, it is smooth and quite stretched.

Cranial Region
Skull - Seen from the front it is wide and slightly curved, seen from the side it draws an irregular curve that, accentuated in the sub region of the forehead, befomes flat along the external saggital crest. Seen from the top, it looks square because of the outstretching of the zygomatic arches and the powerful muscles swathing it. Frontal sinuses well developed and stetched forward, deep forehead hollow and visible median furrow. Occipital crest not much developed. Supraorbital fossae slightly marked.
Stop - Very marked because of the very developed and bulging frontal and because of the prominent superciliary arches.

FACIAL REGION - 
Nose - It is on the same line as the nose pipe. Seen from the side it mustn't stick out from the front vertical margin of the lips but be, with its front, on the same vertical line as the front of the muzzle. It has to be voluminous, rather flat on top, with wide nostrils, opened and mobile, wet and cool. The pigmentation is black.
Muzzle - Very broad and deep. The width of the muzzle must be almost equal to its length, which reaches 3,4/10 of the total length of the head. Its depth is more than 50% the length of the muzzle. Due to the parallels of the muzzle sides and to the fullness and the width of the whole jaw, the anterior face of the muzzle is flat and square. The nasal bridge has a rectilinear profile and it is rather flat. The lower side profile of the muzzle is determined by the upper lips, the suborbital region shows a very slight chisel. 
Lips - Rather firm. Seen from the front, the upper lips form at their disjunction an upside down "U" and, seen from the side, hang moderately. The commisure is rightly evident and it always represents the lowest point of the lower side profile of the muzzle. The pigmentation is black. 
Jaws - Very wide, strong and thick, with a very slight shortening of the upper jaw with a subsequent light prognathism (undershot mouth). The branches of the lower jaw are very strong and, seen from the side, are quite curved, the body of the lower jaw, well accentuated forward, points out well the marked chin. The incisors are firmly placed on a straight line. 
Cheeks - The masseter region is full and evident, but not hypertrophic. 
Teeth - White, big, complete in growth and number. The lower jaw incisors pass only slightly (about 1/2 cm) their correspondent ones on the upper arch, so the bite is slightly undershot. 
Eyes - Of medium size compared to the size of the dog, in a sub-frontal position, well spaced. Rima palpebrarum nearly oval, eyeballs slightly protruding, adherent eyelids with the borders pigmented with black, the eye mustn't let the sclera be seen. Third eyelid strongly pigmented. Iris as dark as possible according to the colour of the coat. Look intelligent and alert. 
Ears - Of medium size in relation to the volume of the head and to the size of the dog; covered with short hair, of triangular shape, with rather pointed apex and thick cartilage, in a high position, much above the zygomatic arch, with a wide bottom, hanging, they stick to the cheeks without coming down to the throat. Quite outstretched and slightly protruding at the joint, they become semi-erect when the dog is watchful. They usually get amputated in a equilateral-triangular shape.

NECK - 
Top line - Slightly arched. 
Length - 3,6/10 of the height at the withers, that is equal to the total length of the head.
Shape - Of oval section, strong, very muscular, with a marked disjunction form at the nape. The perimeter, at half length of the neck, is about 8/10 of the height at the withers. Harmoniously joined with the withers, shoulder and chest, the neck has its ideal direction at 45ƒ from the ground and at right angle with the shoulder. 
Skin - The lower margin of the neck is practically without dewlap. 

BODY 
Compact, strong and very muscular. Its length is 11% over the height at the withers, with allowance of ±1%.
Top line - The back region is rectilinear with a slightly lombar convexity. 
Withers - They clearly rise on the dorsal line and over the rump level, are high, long, wide. They are lean and joint harmoniously to the neck and to the back.
Back - It is wide, very muscular as the whole upper line of the trunk, slightly climbing from the back to the front and with a strictly rectilinear profile. Its length is approx. 32% of the height at the withers. 
Loins - The lumbar region has to be short, wide, well joined to the backand to the back and to the rump, very muscular, very solid and, seen from the side, slightly convex. Its length, slightly higher than its width, is equal to 20% of the height at the withers.
Croup - It is long, wide, quite round due to the considerable growth of the muscles. The length, measured from the ridge of the hip to the ridge of the nates is equal to 32% of the height at the withers. Its average width is equal to 23% of the height at the withers, its inclination on the horizontal line, on the basis of the ilium-ischiatic line is of 28º/30º, on the basis of the line from the ridge of the hip to the insertion of the tail is of 15º/16º. Therefore the rump is slightly inclined. 
Chest - Wide, well inclined and open, with well grown muscles. Its width, in close relation with the width of the thorax, reaches 35% of the height to the withers, the breast-bone is at the same height as the tip of the shoulders. Seen from the side, the chest is outstretched forward between the fore legs and slightly convex. 
Thorax - It has to be well grown in the three dimensions with long, oblique, wide and well hoped ribs with wide intercostal spaces. The 4 false ribs are long, oblique and open. The thorax reaches down at the elbow and its height is equal to half the height at the withers. Its width, measured at half of its height, is equal to 35% of the height at the withers and decreases slightly towards the sternum region without forming a carina. The depth (saggital diameter) is equal to 55% the height at the withers. Its perimeter is over 35% the height at the withers. 
Underline and belly - The sternum region is lean, long, wide and seen from the side it outlines a semicircle with a wide radius which caudally goes up smoothly to the abdomen. The abdomen region is neither hollowed nor relaxed and, seen from the side, rises up from the sternum edge to the groins with a smooth curve. The hollow on the side is not very marked. Tail - It is inserted quite high on the rump line, it's thick at the root and not too tapering at the tip, and if stretched is not too much over the hock. When not in action is low. Otherwise is horizontal or slightly higher than the back, it must never be bent to form a ring or in a vertical position. It gets amputated at the 4^th rib.
