"Dragging. This method is best accomplished in a desolate place, as it sometimes arouses compassion in unrelated observers. With your dog on its leash, attach the free end to your car's bumper or to the rear undercarriage of your vehicle. Once done, get in your car and begin to drive at high speed. Five minutes will probably do the trick. If not, try and other five. Remember to remove any gravel that may lodge in the dog's flesh afterwards."
