You can add fruits and veggies if you want – but you don’t have to. If you do, make sure the veggies are cooked and pureed and the fruit is mashed or pureed. Cooking and pureeing helps to break down the cellulose making it easier for the dog to digest as dogs don’t produce cellulase (the enzymes necessary to breakdown cellulose).
Don’t add only organ meat – I suggested hearts and gizzards because they are considered muscle meat and are cheap. Organ meat would be liver, kidneys, spleen, lungs, etc. The only organ meat you’ll probably be able to find at a grocery store would be liver. Liver is fine to feed but feed it in moderation – it’s very nutrient dense and should account for no more than 5% of the diet. You could certainly buy ground meats, whole roasts and such and dice them (although these cuts are a bit more expensive). You could also supplement with a meal of raw meaty bones a few times a week if you aren’t opposed to feeding bones (pork necks, chicken leg quarters, turkey necks, etc.) – RMB’s will provide dental benefits as well.
