Dog (Fallout 4)

Dogs are animals that can be found in Fallout 4, and act as companions towards humans. While the different breeds that may be in-game are possibly unknown, this one being a German Shepherd is confirmed to be the companion to the Vault 111 dweller as seen in the end of the trailer.

Background
Most commonly seen as feral beasts that plague the wastes and kill livestock, they are necessary for many struggling wastelanders. There is also the rare cases of domestic breeds that act as companions towards their human counterparts.

Humans are the only species known to truly tame and domesticated these canines. Also other types of sub/meta-humans show an interest in doing the same, dogs of all types, including feral dogs, are well-known to attack or flee from them on sight.

Biology
Through the 200 years since the Great War, dogs have remained unaltered by radiation, seemingly a miracle. Other than that, there is no reason to believe that the biology of dogs in the Fallout universe differs from dogs in the real world, besides having a rougher appearance than domesticated dogs, unsurprising in the harshness of the Wasteland.

Appearances
Dogs appear in Fallout 4.
