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 />
