You should feed 2-3% of the dogs IDEAL weight, daily. 80% of the meal should be protein(meat), 10% bone, and 10% organ. Split that amount into 2 meals if you feed twice a day and 3 if you feed 3 times a day. There is a good yahoo group on this topic. I'm not sure if I can post that info here so you can pm me for that info. Good luck with whatever way you choose!
