This is something that has been nagging me about Fallout 4. You find a normal German Shepard. How? All the dogs in the wasteland are feral and mutated, and yet Dogmeat is perfectly normal and healthy? I know he was with the minutemen before he meets the sole survivor, did i miss some dialogue or something explaining him? Or is it just a mystery no-one has asked about yet? Maybe he's from a vault, i don't know.
