I make my own dog biscuits and when a client leaves I always give them some in a goody bag to take home. I have a couple of recipes I make and the one that I have that is popular is:

Honey and Cinnamon Dog treats: 1/2 cup honey, 1/2 cup veg oil, 1 tsp vanilla, 1 egg, 2 tbsp milk, 2 1/2 cup flour, 1tsp baking soda, 1/2 tsp cinnamon,

Preheat oven to 375. In a large bowl combine veg oil, honey, vanilla, cinnamon, milk, & egg. Then stir in baking powder & flour. Roll out dough with a rolling pin. Cut out shapes with cookie cutters. Bake 13 - 15 mins.
