Just cook your chicken until it is easy to bone. Just like you were making chicken stew for yourself. I use the pressure cooker to make it faster, but a crock pot would do, too. When the chicken is done the small bones are very soft, you do not need to worry about giving those to dogs, or eating them yourself, for that matter. (You can even cook the chicken parts we do not eat, that you do not want, such as gizzard, feet, guts, you name it, dogs like it). Remove large leg bones, but neck bones are fine in the dog food. Now, put equal parts of chicken and rice with the right amount of water for the rice. Example: 2 cups chicken scraps, 2 cups rice, 4 cups water. Cook that with any leftovers you have like potatoes, carrots, old stale bread, etc. I do it on clean out the frig day, which is the day before the trash truck comes, also a good day for processing chickens. Put it in refrigerator containers, or mason jars, keeps a week in the frig. Freeze it for as long as 6 months. I use it like I would use canned dog food, on top of dry kibble. Dogs love it!
