Preheat oven to 350 degrees. Combine flour, dry milk, salt, and sugar. Cut in drippings until mixture resembles cornmeal. Mix in egg. Add enough water so the mixture forms a ball.

Pat out dough 1/2 inch thick with your fingers on a lightly oiled cookie sheet. Cut with doggie biscuit cutter, and remove scraps. Pat out scraps on another cookie sheet, and proceed as before.

Bake 25-30 minutes. Remove from oven and cool on cake rack.

Personal note: I did a few with the bone-shaped cutter, but I also made some in other shapes as well. Any cookie cutter will work. I have a good collection of tin cookie cutters in lots of shapes from a foot to a fish....the dog's own Christmas cookies!!!
