Line a large rimmed baking sheet with parchment paper (which will help with easy clean-up; important during busy Halloween time!)
Open the crescent rolls dough and separate along the perforated lines into 8 triangles.
Lay one piece of dough on a cutting board and, using a sharp knife, cut along the long side into 1/2-inch long strips.
Wrap strips around hot dog, leaving a spot for the eyes along one end.
Bake until the dough is golden and cooked through and the veggie dogs/hot dogs are warmed through, 15-20 minutes.
Add eyes. I like to put the cream cheese in a small baggie and cut the corner off, then pipe the cream cheese on. Plop in an olive pupil (use a toothpick to position exactly right if you like) and they're ready!
