Preheat your oven to 375°F (190°C) and line two baking sheets with parchment paper.

Let the pizza dough sit at room temperature for about 20 minutes, then dust your work surface with flour and divide the dough into 10 equal pieces.

Roll each piece of dough into an 8-inch long rope, thickening the ends, snip each end about 1 inch deep, and pull apart to form bone tips.

Arrange the shaped breadsticks on the prepared baking sheets, brush with melted butter, sprinkle with Parmesan, and bake for 15 minutes.

Sprinkle shredded mozzarella on each breadstick and return them to the oven for an additional 5 to 7 minutes until melted and bubbly.

Let the breadsticks cool slightly before serving with marinara sauce for dipping.
