Dog Biscuits Ingredients 3 cups whole wheat flour 2 cups old fashioned oats ¼ cup wheat bran ¼ cup powdered milk 1 ¼ cups water one-fourth to one-third cup peanut butter (or pumpkin) 1 large egg ½ teaspoon garlic powder Directions Mix everything in a large bowl. Knead with your hands like bread dough, or use kneading attachment to stand mixer, until dough is no longer sticky. Dough will be dense but pliable. Rollout to about ½ inch thickness. Cut into whatever shapes you want. Bake at 275 F for at least 1 ½ hours or as much as 3 hours, depending on how tough your dog’s teeth are. Note: If the dough seems to dry, add more water or peanut butter/pumpkin. If I have leftover egg white, I add that if more moisture is needed.
