Mix dry ingredients. Blend in fat until mixture resembles cornmeal. Add egg-water mixture, mixing until a ball is formed. Turn onto a floured board and knead well, adding more flour if sticky. Roll out and cut into shapes, and place on foil lined pan. Bake for 30 minutes or longer depending on thickness. When cool, bones should be hard. If not, bake an additional 15 to 20 minutes at 325ºF.
