I spent quite some time at Carol Webb's when I was going around meeting breeders and we talked about feeding and giving raw meat. One thing I remember her saying is that it's important to not feed raw meat and dry kibble in the same meal because they get digested at different rates. In the future I will probably try giving Zip a handful of raw meals a week and see how she does. I'm not sure how I'd make that transition though. Right now she's doing fine on Innova.
She is correct about the kibble and the raw meat..
