Preheat oven to 180°. Combine all ingredients together in a bowl and knead together into a dough. Press mixture into a greased baking tray and bake for about 20 minutes then remove from tray, place on cutting board and using a pizza cutter cut into small cubes then return to baking tray. Bake at reduced temperature of 130° for an additional 40-60 minutes. Check dog treats at 40 minutes, and every 5 minutes thereafter, until treats are dried and golden brown. The treats will continue to dry out as they cool.
