I made these the other day, really easy, and you know exactly what goes in biscuits if you make them yourself. The gang absolutely loved them.

Tuna/Milk Bone Dog Biscuits
· 3/4 cup hot water
· 1/3 cup margarine
· 1/2 cup powdered milk
· 1 teaspoon salt
· 1 egg, beaten
· 3 cups whole wheat flour
· Variation: increase margarine to 1/2 cup and add 2 teaspoons sugar
· 1 can of 180gm tuna
In large bowl pour hot water over the margarine. Stir in powdered milk, salt, and egg. Add tuna. Add flour, 1/2 cup at a time. Knead for a few minutes to form stiff dough. Pat or roll to 1/2 inch thickness. Cut into bone shapes. Bake at 325 degrees for 50 minutes. Cool. They will dry out quite hard. Makes about 1 1/4 pounds of biscuits. Costs around 30 cents per pound.
