Get a dehydrator and place think cuts of trimmed chicken and beef. That easy. Cook it until its hard for the dog. Try setting it up before bed. It maybe done in the morning but most likely when you come home from work. We make a lot and freeze it in small bags. Bring out the small bags one at a time so its stays fresh longer. Our girls love it. You can try lamb and turkey too. Don’t know about fish. The smell in the house maybe to much with that one.
Really easy to do too.
