Dog

Dogs are creatures found across the post-War United States. Many have remained domesticated pets, but many more have turned feral and hunt the wasteland in packs. The dogs that survived the War are a larger and tougher breed, now almost wolf-sized. Even so, just as they have in ages past, many dogs have remained faithful and beloved companions. Post-nuclear canines include Dogmeat, the companion of the Vault Dweller, and their descendant, the companion of the Lone Wanderer.

Background
Dogs are domesticated creatures that serve as companions or used for protection. Some dogs have been less effected by radiation exposure than others after the Great War, and some have been turned into cyberdogs. 

Dog


Regular dogs with standard statistics and characteristics but no special attributes.

Legion mongrel


Legion mongrels are dogs owned and bred by the houndmasters of Caesar's Legion. Mongrels are mainly used in combat and scouting missions by the Legion. Because of their thick, shaggy hair (as seen in the picture) and their red-colored eyes, they are of a distinctly different breed than most dogs found in games.

Vicious dog


Vicious dogs are a nearly hairless and apparently, partially ghoulified species of wasteland canine. Ruthless survivors of the wastes, these starving, irradiated mutts will attack anything that moves.

Mongrel


Mongrels are terribly irradiated, mutated forms of dogs. They are red and ghoulish and usually hunt in packs randomly found throughout the Commonwealth and Appalachia. There are many variants of mongrels, the worst of which are the alpha variants.

Mutant hound


Unlike other species of dogs mutated by radiation, these dogs are also mutated by FEV, giving them a distinct rough green exterior. They hunt with super mutant packs and they also come in a glowing variant.

Appearances
Dogs appear in all Fallout games.
