I second this...I feed Purina One and my dogs do great on it, but PO or Dog Chow is as low as I'll go. I've fed them some meat and bones on occasion too, but just stuff from the grocery store...I would have a problem seeing my dogs tear into a whole animal...funny how it doesn't bother me if it's already cut up and packaged.If you're stuck with Wal-Mart kibble, try Purina Dog Chow or Purina ONE. They're WAY better than Ol' Roy. And supplementing with raw meats is great, since those foods are high in grains.
Eeeww....beaver. I bet my dogs would love it, but still.....eeeewwww.
