01 - Preheat oven to 350°F and line a baking sheet with parchment paper.
02 - In a large bowl, combine grated apple, grated carrot, flour, and oats. Mix thoroughly. Add egg and applesauce, stirring until dough forms. Add water 1 tablespoon at a time if dough is too dry.
03 - On a lightly floured surface, roll dough into sticks approximately 4 inches long and ½ inch thick.
04 - Place sticks on prepared baking sheet, spacing slightly apart.
05 - Bake for 40-45 minutes until golden and firm. For extra crunch, turn off oven and let sticks cool inside for an additional hour.
06 - Allow chew sticks to cool completely before serving to your dog.
