If you are feeding raw meat, bones, and organs (I feed raw commercially available patties that have appropriate ratios of these) then you do not need any fruits, veggies, or grains. We give Lola fruits and veggies as treats though.
YOu should feed her 2-3 % of the body weight that she should be as an adult dog each day.
The ratio of meat to bone to organs is 80/10/10 5% of the organ should be liver (half of 10%=5%)
I will tag some other raw feeding members, as I can't give you an experieced answer on the bones and offal. Thank you for rescuing a bully!!
you can also try beef, its availability makes it a good choice. And dogs should be on more red meat than poultry for sure.
