01 - Preheat your oven to 350°F and line a baking sheet with parchment paper.
02 - In a large bowl, combine the grated apple, grated carrot, flour, and oats. Mix thoroughly to distribute ingredients evenly.
03 - Add the egg and applesauce to the mixture and stir until a dough forms. If the dough is dry, add water 1 tablespoon at a time until it comes together.
04 - On a lightly floured surface, roll the dough into small sticks about 4 inches long and ½ inch thick.
05 - Place the sticks on the prepared baking sheet, spacing them slightly apart to allow for even baking.
06 - Bake for 40–45 minutes, or until the sticks are golden and firm. For extra crunch, turn off the oven and let the sticks cool inside for an additional hour.
07 - Let the chew sticks cool completely before serving to your pup.
