How to Make Hard Puppy Treats
- 1). Preheat the oven to 275 degrees F and lower the top rack to the lower third of the oven. Cut a piece of parchment paper to fit the bottom of a cookie sheet.
- 2). Combine 3 cups whole-wheat flour, 2 cups old-fashioned oats, 1/4 cup wheat germ and 1/4 cup nonfat powdered milk in a large mixing bowl with a wooden spoon. Add 1/2 tsp. garlic powder to the dry mixture.
- 3). Blend 1 large egg, 1 1/4 cups of water and 1/2 cup creamy peanut butter in a blender or food processor until smooth. Add the wet mixture to the mixing bowl with the dry combination and stir until completely combined.
- 4). Sprinkle your work surface with flour and roll the mixture to a 1/2-inch thickness with a rolling pin. Dip a 3-inch bone-shaped cookie cutter into flour and press over the rolled-out mixture. Place the bone-shaped mixture onto the lined cookie sheet.
- 5). Bunch up the scrap dough, reroll and press more bone-shaped biscuits. Bake the dough at 275 degrees F for 90 minutes, or up to three hours for drier biscuits.
- 6). Store the biscuits in an airtight container, but leave the lid propped a bit for three days to ensure that the dog biscuits are completely dried out.
