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 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.
04 - On a lightly floured surface, roll the dough into small sticks approximately 4 inches long and ½ inch thick.
05 - Place the sticks on the prepared baking sheet, spacing them slightly apart to allow for even cooking.
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 before serving to your pup to prevent any risk of burning.
