We have come to the second episode of the description,on technical basis,of the correct morphology of the Chihuahua. In this second issue we continue to deal with the description of the head of the Chihuahua, in order to master the concept of breed and analyzing expression profiles and in detail the regions of the head (cranial and facial)eyes,ears and teeth.In this study we will use the tools that the science gives us,angles and lines(sagittal medial line,horizontal line,corners of the eyes,facial lateral axes and angles)to clearly understand few basic notion. |

EXPRESSION The expression of Chihuahua is intelligent,caring,sweet,alert,lively and absolutely never mean or frowning.Each breed has an Expression of its own,and so characteristic of great weight in assessing the quality of a subject. The expression is a character difficult to define and describe, it is not an objective fact or a quantifiable one,such as colour,weight and size. To be able to describe it we will use graphics, but nevertheless in order to grasp it, you need the experience that comes from the accurate and continuous observation of the subject. The expression is given by the regions and the characteristics of the head and its components: the skull, foreface, the planes of forehead and of the bridge of the nose, facial longitudinal axis, the stop position, shape, size and colour of the eyes, of the set, size and carriage of the ears. Every feature of the head helps to define the expression of our little Mexican boy, we can not, for example,forget the importance of the position of the mandible and maxilla,the good development of the chin the skin supple and thin,the broad nose and its pigmentation and so on. Furthermore, we must add, as integral factor, the relative and absolute beauty with its strengths and faults and the ethnic characteristics, required by the standard, to be found in the regions of the foreface and skull of which we have already discussed in the previous issue. It 's time now to talk about, eyes, ears and teeth. |

EYES |
EARS |
|
The ear is well set when the lowest point of insertion is aligned with the lateral corner of the eye.The Chihuahua's ears lobe is inserted low on the skull, but are high when the dog is alert. The insertion at the base is moderately large,placed more on the sides of the skull rather than above it,when resting their median axis should have has an angle of approximately 45° degrees compared to the horizontal line, approximately,their position is called +10 to -10 as if we were looking at a clock's dial.When paying attention or in alert,the Chihuahua reduces the angle's opening, bringing the ears closer and in a higher position.When relaxed or in some specific mood the Chihuahua flattens his ears on the skull.The ear standard refers to a 45 degree angle at rest. The ears are carried in erect position only, are big but not huge,always in close harmony with the head and well spaced apart,because of their size the Chihuahua's ears might take sometime to be fully erected,and until fully grown sometimes the tips are weak and can fold forward or backward.Is instead a serious fault if the cartilage is too thick and heavy because that prevents the ear to be erect.Small ears placed high on the head like those of cats will give the Chihuahua a Pomeranian look and that is a type fault. |
TEETH In the past in when judging toys breed dentition was often undervalued, were today,rightly,we look for correct and complete,dentition,as required by the standard.Age and the small size of the incisors and their root can cause the loss of teeth in Chihuahua (as in all dwarf breeds )in this regard, we must give credit to the CCC (Italian Toy Breeds Club)to have established the certificate of full dentition. In this way the teeth of the subject is carefully judged verified and certified,and later dentition changes will not be seen as a genetic fault.When judging Chihuahua dentition you have to examine the bite, the number,the size,cleanliness and alignment of teeth.The Chihuahua jaws must be of the same length.The closure may be scissor bite that means the upper incisors inner face touching the lower incisors outer face,the upper incisors have a slight forward lean than the lower,pincer- bite is also accepted,that is when the upper incisors rest on the lower incisors.When the jaws are not equal in length we face two faults: undershot or overshot. Undershot, when the upper jaw is shorter than the lower jaw, a severe fault in the ring but does not prevent, however,to the subjecta strong and vigorous physique. Overshot:, when the lower jaw is shorter than the upper jaw compromising the visibility of the chin. This inequality of the maxilla and mandible is a serious fault in the standard and is considered an absolute,congenital,degenerative disqualification fault. An open bite prevents the touch of the upper and lower incisors when the mouth is tightly closed, the tongue usually protrudes to a certain extent. Generally this is due to deviations of the jaws and / or the teeth. The tongue should never be visible when the mouth is closed. The lack of some incisors in both jaws is a fault closely related to the maxillary arch width, and so related to the muzzle that could be too pointed. |
