here's one my friend made for the Humane Society! My dogs loved them! She also said that she just used regular flour and added some oatmeal!

She also cut them out in different shapes and sizes!

2 1/2 cups whole wheat flour
1/2 cup powdered milk -- non-fat
1 1/2 teaspoons sugar
1 teaspoon salt
1 whole egg
8 ounces peanut butter
1 tablespoon garlic powder
1/2 cup cold water

Mix above ingredients together, adding water after other ingredients are mixed. Knead for 3 to 5 minutes. Dough should form a ball. Roll to 1/2 inch thick and cut into doggie bone shapes. Bake on a lightly greased cookie sheet for 30 minutes at 350 degrees.
