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 Rottweiler’s nose
Lips
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.
Teeth
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
Rottweiler’s 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.
