This spooky spider Halloween hot dog (spider dog) recipe is easy to make with crescent rolls, hot dogs, and ketchup for a Halloween party appetizer.
Preheat the oven to 375 degrees F (190 degrees C).
Unroll crescent dough; pinch or press perforation between triangles to form 4 rectangular pieces. Cut each rectangle in half lengthwise to form 8 narrow strips. Set aside.
Cut a 2-inch slice through center of one end of 1 hot dog; cut two more 2-inch slices on either side of original slice, so "legs" are about the same thickness. Repeat on the other end of hot dog. Repeat cutting slices ("legs") into remaining 7 hot dogs.
Roll 1 crescent strip around center of each dog. Place spider dogs on an ungreased baking sheet.
Bake in the preheated oven until golden brown, about 11 minutes. Dip a chopstick into ketchup; dot "eyes" onto each spider. Serve spider dogs with remaining ketchup.
