I've been feeding kibble, ground raw, prey model raw, and canned all mixed together as I see fit for a while now.
Lately Buzz has been getting Honest Kitchen mixed with his Canine Caviar at every meal. It's gone over really well.
Last night though, dinner was a pork tail and 1/3 his normal kibble serving and part of a bully stick.
Bailey has been eating Earthborn and Sojos for the last couple weeks and seems to do really well on it, too.
