Black Mirror Wiki

Dogs are autonomous robotic quadrupeds, equipped with a series of lethal weapons. They serve as the primary antagonists of the episode Metalhead.


Very little is revealed about the robots, other than they are relentless and brutally efficient killing machines which seem to be focused on exterminating what remains of humanity.

It is not shown whether they are fully autonomous, or are actually being controlled remotely by humans. Their design is similar to that of the real life BigDog manufactured by Boston Dynamics.


  • Explosive Tracking Devices

When dormant and in close proximity to a human, the Dog shoots out a small ball which explodes in mid air, causing shrapnel to embed into the body of the human. Each piece of shrapnel is equipped with a tracking device, allowing the Dog to hunt the human down at a later time.

  • Built In Firearm

The robots have a small, self loading gun built in to their right front leg, which can be used to shoot and kill humans in fairly close proximity.

  • Data Probe

Also built into the front leg, allows the Dog to connect with and control/manipulate digital technology, including computer controlled vehicles.

  • Solar Charging

Likely one of multiple ways the Dog's can recharge, enables them to recharge whilst lying dormant.
