01 - Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
02 - In a large bowl, combine the grated apple, grated carrot, flour, and oats. Mix thoroughly until evenly distributed.
03 - Add the egg and applesauce to the mixture and stir until a dough forms. If the dough is too dry, add water 1 tablespoon at a time until it comes together into a workable consistency.
04 - On a lightly floured surface, roll the dough into small sticks about 4 inches long and ½ inch thick, ensuring uniform thickness for even baking.
05 - Place the sticks on the prepared baking sheet, spacing them slightly apart to allow for air circulation during baking.
06 - Bake for 40-45 minutes, or until the sticks are golden brown and firm to the touch. For extra crunch, turn off the oven and let the sticks cool inside for an additional hour.
07 - Let the chew sticks cool completely on the baking sheet before serving to your pup to ensure proper texture and prevent burning.
