we made our own dog food. Started with the boy that was getting old and had a lot of joint issues. He lived to 15. The girl had sensitive stomach, she lived to 16. New dog didn't like it, which boggles my mind.
We picked up lamb and pigs at the 4H auction every year. We kept the lamb chops and had the rest of the lamb ground up. The dog food was a combination of ground turkey, ground pig, and ground lamb along with some other stuff. Lamb at the 4H auction was incredibly cheap. Hogs, we got them as cheap as $0.75/lb. Added rice, eggs and supplements and pressure canned the food.
