I feed kibble in the mornings and then a variety of raw stuff in the evenings too, I also haven't found that the dogs have gone off their kibble but they are gannets and will eat whatever's put in front of them. In a typical week they might get 2 meals of chicken wings, one of a portioned rabbit carcass, one of lamb ribs, one of tripe, one of sardines and one of NatureDiet wet food, they like the variety and the bones keep their teeth really clean. Tilly can't have this diet any more though, she's now on prescription food only so I'll be keeping a close eye on her teeth.
