Fallout 4 now has it's own Dogmeat mod!
There appears to be nothing modders won't do these days, one of the most recent mods let's you be the trusty little canine sidekick Dogmeat. Who said the game needs Humans? All we need now is for every AI to be turned into a Dog and we can have Dogout 4.
Grab Fallout 4 today and start digging for bones (or humping legs)!
