Freeze the hot dogs for about 2-3 hours or overnight, until solid.
Preheat an air fryer to 350°F (175°C).
Using a vegetable peeler, shave the frozen hot dogs into thin slices.
Place the shaved hot dog slices in the air fryer basket. Lightly mist with cooking spray.
Air fry the hot dog fries for about 5 minutes, or until crispy. Shake the basket halfway through to ensure even cooking.
Serve immediately with your favorite dipping sauces.
