Raw--fish, veggies, chicken, beaver, moose meat, whatever other kind of meat my friends and neighbors feel like donating to the cause. Fortunately, where I live, it's actually cheaper to feed raw than kibble. I could never afford to feed 15 dogs a decent kibble. The shelter I foster for gives us a couple bags of food a month. I throw it in with their slop mixes occasionally. Course, my dogs don't think it's food. Kibble is a treat!
