If frontal and nasal lines are not parallel to each other it is a default. The other deformity is an improper dermic pigmentation of nasal lobe in the Rottweiler when nose is whitish or spotted and also split.
Improper structure of Rottweilerĺs nose
When examining Rottweiler dog for normality, you should pay special attention to skin pigmentation. Lips and gingivae must not be of pink color and it is a serious deformity, because skin depigmentation of these areas may be indicative of general depigmentation. Lips of Rottweiler must be tightly closed and be of black color. Good gingivae must be of dark color.
Adult Rottweiler must have 42 teeth according to the standard. The teeth must be strong and without defects. Due to the structure, assignment and disposition, one may find four types of Rottweilerĺs teeth : permanent or molar teeth; premolar, or foregrinders; incisors and tushes. When the dog is examined for the standards compliance, an imaginary line dividing the jaws into halves is drawn.
There are 3 teeth on both left and right of this line - front, central and back incisors. Further these teeth are followed by tushes and each of the tushes is followed by every 4 premolar teeth. The first premolar tooth of Rottweiler (bicuspid tooth) is too small; the premolars following this tooth are bigger. The last, fourth premolar tooth being in the upper jaw of Rottweiler is the biggest one and named carnivore.
The first cheektooth, corresponding to size and assignment of carnivore tooth, is disposed in the lower jaw over against this fourth premolar tooth. There are 3 molar teeth on each side of the lower jaw, but the upper jaw contains 2 molar teeth on its both sides. Milk teeth appearing in puppies do not have roots. As the number of permanent teeth increases in growing Rottweiler, its milk teeth start to fall out.
There are several parts of the permanent tooth: root grown into bony tissue (it is invisible during external examination of Rottweiler), the neck of tooth that is seen from the soft parts forming the jaw and the most well-defined dental crown produced by very hard and strong dental enamel.
Correct bite (scissor one)
During selection of the dogs for pedigree breeding, Rottweilers that do not have full set of teeth are subject to cull. If Rottweiler does not permanent and premolar teeth then such dog will not be up to the breed standard. During examination of the dog for compliance with the standards you should pay attention to the occlusion (how the upper and lower jaws are interlocked when mouth of Rottweiler is closed).
Normally a scissor bite is considered to be a correct one. In this case the incisors arranged in the lower jaw adjoin the back part of incisors that are in the upper jaw with their front part. At that the teeth of Rottweiler become locked: tushes of lower jaw are disposed in the spaces between the corner teeth and the tushes of upper jaw. Such interlocking of teeth provides a good snatch.
