Here's one that I've made several times (the ones I had the pic of..)

Peanut Butter Dog Biscuits

2 1/2 cups whole wheat flour
1/2 cup non-fat dry milk powder
1 teaspoon sugar
1 teaspoon salt
3 tablespoons of margerine
3 tablespoons of peanut butter
1 egg

Mix ingredients with about 1/2 cup of cold water. Knead for 3 minutes. Dough should form a ball. Roll to 1/2 inch thick and cut into shapes with cookie cutters (I have bone shaped ones). Bake on a lightly greased cookie sheet for 30 minutes at 350 degrees F.

I normally double the recipe....my doggies all love them!
