Are you feeding the BARF diet or Primal Raw, I'm confused.
You may have to supplement with omega 3 (found in wild atlantic salmon oil) and calcium if there is no bone or bonemeal in the food. You can give your dog a crushed eggshell for calcium as well. You need to balance the calcium with the phosphorus in the meat. The ratio should be 1:2 (calcium to phosphorus).
In order to really enjoy a dog, one doesn't merely try to train him to be semi human. The point of it is to open oneself to the possibility of becoming partly a dog. ~Edward Hoagland
