1 3/4 cups whole wheat flour
1/2 cup oatmeal
1/2 cup cornmeal
1/4 cup liver powder (available at health food stores)
2 tablespoons brewer’s yeast powder
1/4 cup bone meal powder
3 tablespoons powdered mild
2 eggs, lightly beaten
3 tablespoons wheat germ oil (vegetable oil or bacon drippings may be used instead)
1/2 cup water

Preheat oven to 325° F. Combine flour, oatmeal, cornmeal, liver powder, brewer’s yeast, bone meal, and powdered milk in a food processor or blender, or mix in a large bowl. Stir in eggs, oil, and water, mixing thoroughly. The dough will be stiff and dry. Remove dough to a lightly floured surface or pasty cloth. Roll or pat into a rectangle that is 1/4 to 1/2 inch thick. Cut into bone shaped biscuits with a small knife or use a bone shaped cookie cutter. Roll the leftover scraps of dough and cut into shapes until all the dough is used. Place on a lightly greased or parchment lined baking sheet, and bake for 40 to 60 minutes until brown and dried through. Cool on a rack.
