Dog (Fallout 4)

Dogs are animals that can be found in the Commonwealth, the Island, and Nuka-World

Gameplay
Humans and super mutants domesticate dogs. Some mongrels will attack on sight but can be pacified. There are a few different distinct breeds of dogs. Dogmeat may be a companion to the Sole Survivor. Two mutated counterparts of dogs can be found in the Commonwealth: the ghoulish mongrels and the mutant hounds. Dogs have special animations where they can grapple enemies down to the ground and hold them in place allowing their masters a brief advantage in combat.

Attack dog
They are usually seen in raider camps or with Gunners, Minutemen or Brotherhood of Steel patrols. They are sometimes equipped with various pieces of dog apparel.

Pack dog
Found in the Bradberton Amphitheater, these dogs are owned by the Pack. They will turn hostile if The Pack is attacked. These dogs can either be mongrels or junkyard dogs, and often have dog armor equipped. They can spawn battling in the cage fight arena against other entities, such as Pack captives, or be wandering around the amphitheater.
