Make ahead of time. Roll the crescent dough around the hot dogs and put them onto a baking sheet. Wrap with plastic wrap and store in the refrigerator for up to 24 hours. When you are ready to eat them, pop them in the oven to bake as directed!
Make 'em mini. Cut puff pastry or a full sheet of crescent roll dough into 1½-inch squares. Wrap little smokies or cut pieces of hot dog in the dough, brush with egg wash, and bake as directed above.
