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 super mutant 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 has a tendency to eat anything, even ghost people, when hungry. This eventually led to him accidentally eating his own explosive collar when it came off after the first Gala Event occurred trapping Elijah and, as his other personality mentions, keeping him a prisoner to his hunger and to Elijah. Like most nightkin, Dog exhibits severe mental trauma from prolonged stealth boy use, resulting in multiple personality disorder. He hates the voice, and is willing to do anything to be rid of it, even going 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. He is quiet, articulate, controlling, and far less pliable than his counterpart. He claims that he 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. He does not care for the treasure of the Sierra Madre, and frequently comments on the Courier's perceived greed. When in combat, he is far less adept than Dog, as he is less accustomed to using the nightkin body and lacks the bloodlust of his other personality.

Quests

 * Find Collar 8: "Dog": The player has to travel to the Villa Police Station and recruit Dog or God.
 * Fires in the Sky: The player has to escort Dog or God to Salida del Sol South to Trigger the Gala Event and hunt down some ghost people for Dog or God to eat.
 * Put the Beast Down: The player must confront Dog or God in the Sierra Madre Casino.

Other interactions
After recruiting Dog and watching him kill and consume one of the ghost people, the player can talk to Dog and, after going through a few speech options, receive the Ghost Hunter perk from him. However, if the player has the Cannibal perk, it is possible to get the Ghost Hunter perk from him without fighting.

Inventory
Much like Lily Bowen, Dog and God are limited in the weapons they can use. These weapons are:

Since Dog/God cannot equip any weapons unique to Dead Money and outside weapons cannot be brought into the Sierra Madre, Dog/God are effectively restricted to Unarmed fighting.

Notable quotes

 * "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."
 * "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 dialogue options "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" remain highlighted even if you have selected them.
 * Sometimes, when clearing out Salida del Sol North with Dog/God, he will fall through the floor and be suspended underneath it.
 * Sometimes Dog/God may be unable to heal when idle or given stimpaks.
 * Sometimes when he is issued to wait, Dog/God will attack the first ghost person he can find before waiting.
 * There is an exploitable bug where you can obtain God's perk without him following you. By having God as a companion, use Elijah's voice to summon Dog's persona. This is only temporary, however; as soon as you dismiss him at his post for Fires in the Sky, this perk will be lost.
 * Dog/God is prone to getting stuck in walls around the villa and may be unable to follow the player in the same cell.
 * Sometimes Dog will bug and repeat the phrase "Let Dog out. Hungry, hate being in here" after you have brought him to the fountain. This is because the game still thinks Dog is in the cage at the police station due to the result of buggy dialogue options when you are convincing him to leave the cage.
 * FIX: If updating the game or returning to a previous save is not an option, the console is the only solution. Go to Dog and open the console, then click him. Remember the first two digits of the number at the top then type set "XX000FBF".bDogFreed to 1. Replace XX with the two digits from before.
