Lightning dogs, also known as Runners or Revivers, are hostile creatures that appear inside the Quarantine Zone in City 17. They spit electrically charged liquid which can cause power failures in electrical equipment, which also deals minor damage to living creatures. Lightning Dogs can reanimate and control of corpses, turning them into electrified zombies.
