Preheat the oven to 400 degrees F and line a baking sheet with parchment paper.
Divide the pizza dough into 8 equal pieces. Roll each piece into a 6-inch rope, then press the ends slightly wider to form bone shapes.
Place the shaped dough pieces on the prepared baking sheet, spacing them evenly.
Stir the garlic powder and dried oregano into the melted butter. Brush the mixture over each breadstick.
Sprinkle the grated Parmesan cheese evenly across the tops.
Bake for 12 to 15 minutes until the breadsticks turn golden brown.
Warm the marinara sauce in a small saucepan or microwave and serve it alongside the breadsticks for dipping.
