i'm sorry for poor harley... wish i could help, i don't know much about cooked diets
but if my dogs would get sick i would stick with lean ground boneless meats and a supercooked mush of brown rice & cooked veggies (all pureed & mixed with the ground meat). very easy to digest, very soft, no raw bones, full of natural enzymes, and also add some active probiotic capsules. the rice and the veggies provide the soluble fiber and the meat gives enzymes, protein and enough calories so the dog doesn't feel starved.... well that's what i would do....
