Smooth-haired, well-built dog, fairly low on the legs, broad, powerful and stocky. The head is quite large in proportion to the size of the dog, but no part should dominate so much that it affects the overall symmetry, makes the dog appear deformed, or impedes its movement. The face is short, its snout wide, blunt and bent upwards. Dogs that have breathing problems are very undesirable. Body short, well formed and not inclined towards obesity, the limbs strong and muscular, the hindquarters high and strong but somewhat light in relation to the heavily built forehead. Bitches should not be as massive or heavily developed as a male.
The dog must give the impression of determination, strength and activity.
Vigilant, entrepreneurial, loyal to the boss, trustworthy, courageous, fearless, but kind in nature.
HEAD AND SKULL
The skull must be large in circumference, the circumference (measured for the ears) must be approximately equal to the dog's shoulder height. Viewed from the front, it must appear very high from the angle of the lower jaw to the highest point of the skull; also very wide and square. The cheeks must be well rounded and protrude sideways beyond the eyes. Seen from the side, the head must be very high and short, from the back to the tip of the nose. The forehead must not protrude flat or convex or face down and the skin on the forehead and head must be very loose and finely wrinkled. The forehead bones are very far forward, wide, square and high; deep, wide and a notch between the eyes. From the stop a wide and deep stop, or furrow, must run to the center of the skull and this must be traceable to the top of the skull. The face seen from the front should be short from cheekbone to nose and wrinkled. The snout should be short, broad and upward and deep from the corner of the eye to the corner of the mouth. Nose and nostrils must be large, broad and black and under no circumstances liver-colored, red or brown; the top lies back, almost between the eyes. The distance from the inner corner of the eye (or from the center of the stop between the eyes) to the tip of the nose must be greater than the length of the tip of the nose to the edge of the lower lip. The nostrils must be large, wide and open, with a clearly visible, straight, vertical line between them. The muzzle is short, broad and bent upwards and very deep from the corner of the eye to the corner of the mouth. The nose roll must not interrupt the lay-out line. The upper lips "chops" must hang thick and wide, very deep; they must extend completely over the lower jaw on the sides (not from the front). They should come from the front to the lower lip and cover the teeth easily. The jaw must be wide, solid and square, the lower jaw must protrude clearly from the front and be directed upwards. Viewed from the front, the different proportions of the face must be completely equal when one draws an imaginary line from the top of the skull to the tip of the lower jaw.
Viewed from the front, the eyes should lie low in the skull, as far away as possible from the ears. The eyes and the stop must be in a straight line, on which the groove is perpendicular. They must be as far apart as possible, but the outer corners must lie within the outer lines of the cheeks. Round in front, moderately large, neither lying deep nor bulging and must be very dark in color-almost black-, they should not show white when the dog is looking straight ahead. Free from clear eye problems.
The ears must be set high - in other words - the front inner edge of each ear must (seen from the front) meet the outer line of the skull at the corner of that circumference, so that they are far apart and so high and far from the eyes as possible. They must be small and thin. "Pink ear" is correct, that is, the ear folds inwards at the rear, so that part of the interior is visible.
Wide square jaw with six small incisors between the fangs, in a regular row, the fangs far apart. The teeth must be large and strong and not visible when the mouth is closed. Viewed from the front, the lower jaw should be directly under the upper jaw and parallel to it.
The neck must be medium in length, very substantial, deep and strong. Well bent at the back with lots of loose, thick, wrinkled skin from the larynx, which forms "jellyfish" on both sides, from the lower jaw to the chest.
The shoulders must be wide, slanted and low, very strong and muscular and give the impression that they are attached to the body. The chest should be spacious, round and very deep from the highest point of the shoulders to its lowest point, where it forms the breast. The chest should be well between the front legs (so no flat sides), the ribs should be well sprung. The forelegs must be very firm and strong, well-developed and well-spaced apart, strong, muscular and straight, with a fairly curved outer line, but the bones of the legs must be heavy and straight, not crooked or o-bony and short in relation to the hind legs, but not so short that the back shines through for a long time, or that it hinders the mobility of the dog and makes it difficult to move. The elbows must be low and free from the ribs. The middle feet must be short, straight and strong.
Chest should be spacious, round on both sides, eye-catching and deep. The back should be short, strong and broad at the shoulder and relatively narrow at the loins. A slight fall in the back, immediately after the shoulder (lowest point), after which the spine must rise to the loins (top must be higher than the top of the shoulders), after which it suddenly bends back to the tail, forming an arc, "Roach Back", a special feature of the breed. The ribs must extend far back, the underline is with a raised belly, which may not hang.
The hind legs must be heavy and muscular, proportionally longer than the forelegs, so that the loins are higher. The heels are slightly bent and run smoothly; legs long and muscular from the loins to the jumps; the lower legs must be strong, short and straight. As a result, the jump joints tend towards each other and the hind feet turn outwards.
The front feet must be straight and turned slightly outwards, of medium size and almost round, the hind feet round and compact. The toes are contiguous and firm, clearly separated, so that the knuckles are high and catch the eye.
The tail must be set low, rather protrude and then bend downwards. It must be round, smooth and with no frills or rough hair. The tail should be of moderate length, rather short than long, thick at the root and rapidly decreasing to a thin point. It must be carried downwards (not showing a certain upward curl at the end) and the dog may not carry it over its back.
The movement is typical, heavy and stocky, which makes it look like he is walking with short, fast steps on the tips of his toes and barely raises his hind foot and thus seems to skim over the ground. He walks slightly forward with one of his shoulders. A vital movement is of the utmost importance.
The hair must have a fine composition, short, dense and smooth (only hard because it is short and dense, but not rough)
any color is allowed.
The weight of a male: 25 KG (55 Lbs.); a bitch 22.7 KG (50 Lbs.) ERRORS Any deviation from the aforementioned points must be regarded as an error.
The quality of the error must be assessed in its correct proportions to the error.
Errors: • Nose roller that completely or partially covers the nose.
Eliminating errors: • Aggression or excessive fright • Breathing problems • Ingrown tail Any dog that clearly has a physical or behavioral abnormality should be disqualified.
Remarks: Males must have two clearly normal testicles, fully descended into the scrotum.
