I just came from the raw diet and had been grinding my own . I stopped because it's too much work with 5 dogs doing everything by myself . I come home from a ten hour day, so much easier to give kibble. The prefered the raw and did well on it. I would grind my meat ever two weeks. bought it in forty pound cases 80 pounds every two weeks. 10% of the diet should be bone. so I would grind necks and backs . legs and thighs and then skinless boneless breast.
