We feed raw prey model 80% meat 10% bone 10% organ. If their stools seem soft we add more bone. If they are straining too much we up the organ which is really rich. They don't get this ratio every day but over the coarse of the week. We supplement just to make sure they are covered for all nutrients. We give coconut oil, raw organic local honey, dried kelp, turmeric -golden paste, dried green lipped mussel powder, and a powdered mix that includes glucosmine/msm/chondroitin sulfate.
We also try to give a lot of variety of meats...pork, beef, beef tripe, bison, alpaca, lamb, sardines(/mackerel( whole not canned), emu. The only meats we really don't feed are chicken and turkey. One of the dogs has a food sensitivity to turkey and one of the others won't touch chicken. We couldn't survive without a stand alone freezer and our raw CO-OP. With the freezer we can take advantage of sales and season specials. We shop the sales at the grocery store and at Costco too.
Heart is treated at muscle meat not organ but it is supposed to be one of the most nutrient dense meats for them. I find organ meat to be more smelly and yucky than muscle meat but if handled when slightly frozen it's not so bad. For bones we give then cut up pork riblets - really cheap and easy to cut up for their bowls. They tend to fight over big high value meaty bones.
We also give them frozen green beans (cooked) for bulk as it makes them fill full but it goes right through them. We also give them seasonal fresh fruits and frozen blueberries. Recently they seemed to be eating a lot of grass in the yard so we added fresh celery. They seem to like it as it is never left behind.
