Main muscles working the Rottweiler’s jaw 1. Temporomandibular joint 2. Mandible (lower jaw) 3. Maxillary (upper jaw) 4. The masseter muscle is the most powerful muscle involved in closing the jaws 5. The temporal muscle raises the mandible 6. The pterygoid muscle is involved in the lateral movements of the lower jaw 7. The digastric muscle is the only muscle tasked with lowering the mandible Powerful, wide jaws Rottweilers have characteristically strong jaws. The lower jaw – the mandible – is connected at the back to the temporal bones, at a joint that works like a hinge. A dog’s jaws basically move vertically (open/closed), although small transversal movements are possible and are seen during mastication. Several muscles are involved in working the jaw Four muscles participate in the process of grasping and chewing food, three of them play a role in bringing the jaws together. Rottweilers are mesocephalic-type dogs Contrary to the Boxer, another molossoid <strong>breed</strong>, the Rottweiler’s head is not brachychephalic (short, wide, round skull) but mesocephalic, which means that the bottom of the skull and the muzzle are more or less the same size. 14
The well-balanced proportions of the Rottweiler’s head permit the physiological implantation of 42 teeth, each with a different role depending on their size and shape: - 12 incisors cut and bite - 4 canines trap, hold and tear - 16 premolars hold, cut and tear - 10 molars cut and crush. Skull dimensions characterise the different types of canine morphology C 3,62 L 20,3 LD 8,34 (Centre de Recherche Royal Canin : Komonski, 2004) C 3,35 LD 8,01 Z 13,37 Z 12,26 Rottweiler Boxer The upper incisors (6) form a scissors joint with the lower incisors (6). 15 L 15,53 Analysis clearly shows that the Rottweiler’s head is almost as wide as the Boxer’s but it is much longer.
