Dog and God

Dog and God are a schizophrenic and captive Nightkin assisting the Courier in breaching the Sierra Madre Casino in the add-on Dead Money.

Background
Virtually nothing is known about his background, but it is known that his name is only "sort of" Dog.

After being captured by a mysterious old man at the Abandoned BoS Bunker, the Courier must work with him to find the treasure at the heart of the Sierra Madre casino and win their freedom, although at one point in the trailer, he is seen attacking the Courier.

Father Elijah recommends Dog/God is the first companion you find upon being given your quest. You find Dog/God in a police station cell in Sierra Madre Police Station, and you must journey down into to station basement to find an audio log, that will apparently wake Dog/God. When you return to the cell, and play the recording, God wakes up instead, and informs you that he knows where the key to the cell is, but he will not come out. You can convince God that you are intelligent and not play Father Elijah's voice. However, if you chose to play Father Elijah's voice as well, Dog wakes up, and joins you as a companion.

Appearances
Dog and God appear in Dead Money.

Trivia
