A puncture wound is more dangerous to animals then a degloving injury because of the nasty anaerobic bacteria that could grow in the wound when it closes up. These anaerobic bacteria are hard to kill and produce copious amounts of toxins which can cause skin sloughing, organ failure and death. The best way to treat puncture wound is often to open it more, flush it and bandage it so that the inside heals first and the outside heals last. This lets it drain naturally and the oxygen prevents aerobic growth.
