Heat the oven to 375 degrees and line a baking sheet with parchment paper.
Unroll the crescent dough on a clean surface and press the seams together to form one sheet.
Cut the dough into thin strips about half an inch wide.
Wrap the strips around each hot dog, leaving a small gap near one end for the face and overlapping slightly to create a bandage effect.
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 two minutes.
Use a small amount of mustard to dot two eyes on the exposed part of each hot dog.
