Feeding both at the same time is just fine for the large majority of dogs. Kibble and canned are digested at different rates too, but no one ever says you shouldn’t put canned food in the kibble because they digest at different rates. A healthy dog can handle changing from raw to kibble to dehydrated to canned with no transition. The fact that most dogs can’t change without transition is because our feeding practices have made their gut unhealthy. Many of us feed our dogs something completely different at every meal.
Some sites realize that feeding raw 100% is more than most people can do so promote feeding raw one meal, kibble the next, to get the benefits of raw. Darwin’s is one of them.
