Dog's head – assessment

Dog's head – assessment.

Here, first of all, the harmony of construction and the correct ratio of the individual parts are taken into account.

U.S. Its size is assessed, shape and color. The organ of smell should be especially developed in service dogs, investigators or hunting. The shape of the nose may vary: with a long back (chart) or short (mops), straight or even hunchbacked or concave (boxer), possibly clearly upturned (dwarf spaniel). Expression” often depends on whether the bridge of the nose under the eyes is full, or frail. The color of the nose should always be in harmony with the color of the coat. In some breeds, a faulty nose may be disqualifying.

Cheeks. Their outline affects the overall shape of the head. Assesses itself: Shape, profile, length and width. Lips (lips - upper lip hanging down) may be different: delicate, search, tightly compact or fleshy, pendulous and wrinkled.

Neck. The neck can be worn differently - almost horizontally (rock mounds), moderately erect (German Shepherd), carried high (boxer), upturned, head set high (Japanese), it can be almost straight or bent, to group (bulldog), moderately thick and thin. The neck of the swan and deer is a drawback. Underdevelopment and laxity of the neck or neck muscles are always considered a defect, and for a working dog as a reason for disqualification, because they prevent him from retrieving heavier game and always testify to a poor build. The skin on the neck can be tight or very profuse, forming folds and dewlap (bloodhound); in some breeds the presence of the so-called. flanges or manes, made of abundant hair.

Skull. Its shape can be very different. The length and width of the skull should be assessed both from above and from the side. May be: angular, round, oval or canoe-shaped, wide or narrow at the base or tapering regularly. The back of the head may be oval, be flat, it may also have a large tumor or even an occipital crest. A more or less distinct frontal furrow runs along the skull. Finally, the leading edge (otherwise - stop, frontal breakthrough) it can be very sharply scratched, forming a step from the forehead to the bridge of the nose, or the edge may be missing, the bridge of the nose is almost in a straight line to the forehead. The frontal fracture is usually associated with greater or lesser expressiveness of the bones of the supraocular arch, which surround the eyes from above, as from below they are protected by the zygomatic bone.

Maxilla and mandible. Bulky are desirable in working dogs, rather simple, with the teeth closely overlapping each other. They can be very long (chart) be short (Pekingese). A layout resembling the letter V, be angular Π or nearly round U. The upper and lower jaws can be of the same length and then the upper and lower dentition overlap, or they can be of different length. Significant shortening of the lower jaw (the so-called. lower jaw) is always a serious drawback. When the maxilla and mandible are properly built, the incisors overlap or cover the lower ones, and the canines of the mandible extend in front of the canines of the maxilla. In utility breeds, the so-called. a scissor bite marked by this, that the lower incisors overlap the upper ones, that their front wall rests lightly against the back wall of the upper incisors. About the tick bite” then we say, when the incisors are positioned that way, that their front walls are flush. Acceptable in some short-headed breeds, and even undershot bite is typical (the lower incisors protrude significantly in front of the upper incisors). The lower jaw can also be significantly bent, then it protrudes in front of the retracted jaw. Exposing the lower teeth is always considered a defect.

In order to. The dentition in his youth consists of 28 milk teeth, and in mature age z 42 permanent teeth. The milk dentition consists of 12 incisors, 4 canines and 12 premolars. Many authors have an enumeration 16 premolars. This is because of the fact, that the 1st premolar as a permanent tooth already appears between 3,5 a 6 months and is mistakenly classified as milk teeth. The dog loses its milk teeth one by one, permanent teeth grow in their place. In addition, they grow at the top 4 and down 6 molars.
