Coupling is disposed between front and hind parts of corpora.
Coupling of Rottweiler delivers impulse from hind limbs to fore
body of the dog. At that movement of the coupling resembles spring
impulse moving forward Rottweiler’s corpus. Ideally, coupling of
Rottweiler must be powerful, wide and deep.
Curple
Canine croup is formed by two haunch bones framing pelvic girdle
and lumbosacral spine. Haunch bones are inclined to horizontal
plane and a little sloped backward. Outlines of Rottweiler’s
curple have round shape (that is necessarily considered in the
standard). According to disposition of the haunch bones and tail
base, the curple of Rottweiler happens to sloping or upstanding.
Both of these manifestations are aberrations. Set of hind limbs is
also very important during evaluation of Rottweiler’s exterior.
Inclination of haunch bones towards the rump has significant
effect on such set. If this inclination is too small then
extension of hind limbs also known as outright back may develop in
Rottweiler. If on the contrary, inclination is too big then in
this case the features of canted croup emerge distinctively in the
dog.
Curples:
а – standard;
б – sloping;
в – upstanding
Tail
According to the standard Rottweiler’s tail is to be short and
very strong. Deformities: very high and very low set of the tail.
Highly set tail as a rule is observed with flat rump and at
rectification of stifle. When tail is low-set, croup of Rottweiler
is usually sloping. After cropping the tail, it must be 1-2
vertebrae left.
Set of the tail: а – high; б – low
Chest and belly
Corpus of Rottweiler includes 2 parts: chest and abdominal cavity
which is protected from above from external mechanical actions of
lumbar vertebrae. Chest contains heart, respiratory apparatus,
blood-vessels that are of great importance for life activity of
all the body. Ribs adjoin dorsal vertebrae. Size of rib curve
directly affects the width of Rottweiler’s chest.
If curve of the ribs is not big (they are almost flat), then chest
appears to be underdeveloped, narrow, but internals (heart and
lungs)–weak. In this case front limbs of the dog will be
considered atypical: they are noted for very narrow set, but the
paws are separated at that.
Excessive curvature of ribs involves wrong formation of
Rottweiler’s chest (domed chest). In addition, position of
forearms appears to be very wide, the elbows appear to be turned
out; talipes with indrawn paws starts to develop.
Rottweilers with
not very wide or domed chest are improper for pedigree breeding
because chest breadth is one of the hereditary features.
