If you're smart, you'll find the sources that sell to the dog food companies and buy the necks, hearts, rib meat, organ meat before they end up on that truck. I buy poultry from a local butcher for 0.25 to 0.50 per pound. I get ground beef mix (rib meat, heart, tongue, liver) from another local for 0.75/lb. Lamb, beef, pork necks.
Then I supplement more expensive products like rabbit and ground salmon.
