I've tried to do the raw or barf diets in the past and i have found that with the big dogs they are pretty cost prohibative for me. The only way that I could keep wieght on my greyhound was to give her the barf diet and it worked great. Occasionally I feed my dogs raw meat, they love pigs feet (walmart), or do cooked oatmeal, tomato juice, glucosamine/msm, and raw liver cut up, or whole pigs feet. She loved it. I was reading on the net that a 160lb dog should have 5lbs of meat a day. That's just a little cost prohibative for me but they'll get it as an occasional treat.
