Heat the oven to 375 degrees and line a baking sheet with parchment paper.
Unroll the crescent dough on a cutting board and press the seams together to form a single 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.
Place the wrapped hot dogs on the baking sheet and bake for 12 to 15 minutes until the dough turns golden.
Remove from the oven and let them cool for 5 minutes.
Use a small amount of yellow mustard to draw two dots on each hot dog for eyes.
