Preheat your oven to 200°F (95°C). Line a baking sheet with parchment paper.
In a mixing bowl, combine the ground beef, grated carrot, and grated zucchini.
Shape the mixture into 12 sticks, about 1 inch thick and 4 inches long.
Place the sticks on the prepared baking sheet and bake for 3 hours, or until firm and dry.
Let the chew sticks cool completely before giving them to your dog.
