Dog and God

Dog is a psychologically disturbed nightkin who helps Father Elijah by capturing "assistants" for him and fitting them with explosive collars. His alternate personality, God (referred to by the former as simply "the voice"), is trying to break Dog free of Elijah's grasp.

The "Dog" personality is activated by the sound of Father Elijah's voice, and the "God" personality is activated by the sound of his own voice (via holotape or radio). When one personality is dominant, the other is said to be in "the cage" or "the basement".

Background
Hand-picked by the Master to serve in his nightkin army, Dog was crushed by the Master's defeat. He eventually found the Sierra Madre, where Elijah took advantage of his need for a "master" figure in order to enslave him, using him as a tool for bringing in potential treasure hunters and later for activating the Sierra Madre Gala Event. Dog is extremely loyal and will follow the commands issued by his master's voice to the letter, even when it puts him in danger. He also appears to suffer from some sort of eating disorder, as he will eat anything, even ghost people, when hungry. This eventually led to him accidentally eating the explosive collar of a deceased treasure hunter, putting him in the same situation as the many victims he had dragged to the Sierra Madre. Like most nightkin, Dog exhibits severe schizophrenia, resulting in "multiple personality disorder". He hates the voice, and is willing to do anything to be rid of it, going even to the point of self-harm. Pain hurts him, but also quiets the voice, so he will go to extremes such as scarring his body and putting his arm in a bear trap in order to make it stop.

The voice – "God" – is very different from Dog. It is quiet, articulate, controlling, and far less pliable than its counterpart. It claims that it only wishes to help Dog, even confessing a protective brotherly affection for him and believes the best way to do that is to eliminate Elijah - only then can he help Dog overcome his hunger and need for a master. It does not care for the treasure of the Sierra Madre, and frequently comments on the Courier's perceived greed. When in control, however, it is far less adept in combat than Dog, as it is far less used to using the nightkin body and lacks the bloodlust of its other personality.

Notable quotes

 * "No, you wouldn't. If you did, you won't escape this place alive. I'd shatter every one of your limbs to splinters and leave you here. "
 * "I'll prop your broken body in view of the Sierra Madre so you can see what you came to steal... forever out of reach as you die."
 * "That Pip-Boy... maybe I'll tear it off your arm, wear it around my neck."
 * ''"Where is Master? Did he go away? Dog will be good this time."
 * OM NOM NOM! (Wild Wasteland trait required)
 * Wish I had a Stealth Boy instead of this bear trap.
 * You look like food, smell like food, Dog hungry.
 * Don't like this place. Want to go back, back to the base. Or the church, miss the church.

Appearances
Dog and God appear only in the Fallout: New Vegas add-on, Dead Money.

Bugs

 * The Dialog "Who's This Old Man That Brought Us Here?", "So You're the one that knows how I got to the villa", "You Brought Me Here to the villa" and "I Want To Know More About The Man Who Brought Us Here" Do not unhighlight no matter if you talking to Dog or God
 * Sometimes, when clearing out Salida del Sol North with Dog/God, he will fall through the floor and be suspended underneath it.
 * Sometimes God/Dog may be unable to heal when administered stimpaks or after combat.
 * Sometimes when giving the wait command to God/Dog, he will attack the first ghost person he can find and then wait.
 * There is an exploitable bug, where you can obtain God's perk, without him being a companion, by having God as a companion, using Elijah's voice to bring out Dog, and dismissing Dog. This is only temporary, as soon as the player dismisses him at his post for Fires in the Sky, the Courier will lose the perk.
