Fallout 4's official modding tools won't be out until next month, but that hasn't stopped Abbalovesyou experimenting in bizarre new directions. Thanks to the Be The Dog mod, you can now play as Dogmeat or any other dog found in the Wasteland. You even get a dog-size Pip Boy. It is slightly peculiar that instead of a deep bark you have an East Coast accent, but given that you can still befriend the actual Dogmeat, you can pretend you're in a Disney tale of canine friends. That or blame it on the radiation.
As you lack opposable thumbs, firearms are out of the question. You get three bite attacks: two bound to your mouse buttons and a third lunging attack.
Unfortunately the Pip Boy doesn't work in first-person, but as the whole thing is far less funny in first-person, that shouldn't be a problem.
