3/4 cup hot water or meat juices

1/3 cup margarine

1/2 cup powdered milk

1/2 teaspoon salt (optional)

1 egg, beaten

3 cups whole wheat flour

In a large bowl pour hot water over margarine.  Stir in powdered milk, salt and egg.  Add flour, 1/2 cup at a time, mixing well after each addition.  Knead 3 to 4 minutes, adding more flour if necessary to make a very stiff dough.  Pat or roll to 1/2 inch thickness and cut out with a cookie cutter.  Place on a greased baking sheet and bake at 325 degrees for 50 minutes.  Allow to cool and dry out until hard.  Makes about 1.25 pounds and costs about 25 cents a pound.
