If you want to incorporate some raw into the diet, then adding 20% of it is ok without worrying about added vitamins and such. If you’re dog eats 2 meals and day then 2.8 meals (or 3) can be a RMB and maybe some organs (heart/gizzard/a little bit of liver). More than that, you’d need to balance the raw meals better. Make them closer to 80% meat/10% bone/10% organs (5 of that liver) and added supplements or give a premade raw. There are some sample recipes in the Raw Food topic. Another option is to make sure he eats a whole chicken (with heart/gizzard/liver), not just the back.
