Kibble size<br />
When dogs are forced to chew, the food particles that enter the stomach<br />
are smaller, which makes the work of digestive enzymes easier,<br />
thus improving digestibility. In tests, the faeces produced by a diet of<br />
Rottweiler 26 were graded ‘very good’.<br />
A large kibble also helps prevent gastric dilatation-volvulus (GDV). The<br />
risk falls when the food is presented in pieces larger than 30 mm<br />
(Theyse et al, 1998). While Rottweilers are much less likely to suffer<br />
from GDV than other giant <strong>breed</strong>s, the risk cannot be ignored, so it is<br />
recommended that the daily ration be split into two servings.<br />
Kibble texture<br />
The texture is the result of a compromise:<br />
- The teeth have to sink deep enough into the kibble to produce a kind<br />
of mechanical brushing<br />
- The kibble must be resistant enough not to<br />
shatter too soon and negate the beneficial<br />
effect on the teeth.<br />
Only a perfect mastery of the cooking and<br />
extrusion process (temperature and pressure<br />
during cooking, length of drying etc)<br />
guarantees kibbles with the right elasticity<br />
to produce both these effects.<br />

To optimise the role of the food in oral hygiene, the Rottweiler 26 kibble contains<br />
sodium polyphosphates*, which are known to curb the deposition of calcium in dental<br />
plaque and so slow the formation of tartar (White et al, 2002).<br />
