For an adult dog try starting with around 2-3% of their ideal body weight. Keep an eye on their weight, then simply adjust amounts accordingly. The Barf Diet is not an exact science and every dog is different. Be prepared to adjust as you go along. You will soon also become an expert poo watcher! Stools will also tell you if you are feeding too much bone or offal. Again, simply adjust accordingly and you will both be fine!
