Preheat the oven to 375°F and line a baking sheet with parchment paper.
Unroll the crescent dough on a cutting board and press the seams together to form one sheet.
Cut the dough into thin strips about 1/2 inch wide.
Wrap the strips around each hot dog in a crisscross pattern, leaving a small gap near one end for the face.
Place the wrapped hot dogs on the baking sheet and bake for 12 to 15 minutes until the dough is golden brown.
Remove from the oven and let them cool for 2 minutes.
Use a small amount of yellow mustard to dot two eyes on each exposed hot dog end.
