Three Dog

Three Dog is the radio host, DJ, and news anchor of the Galaxy News Radio station in the Capital Wasteland in 2277, playing music that would have been heard on the radio in the years leading up to WWII, as well as the immediate post-war era.

Background
Born to parents who made their way in the world as members of a traveling theater group, Three Dog grew up listening to rock music, hating the government that he never knew (but surely caused the nuclear holocaust), and fully believing in the rights of free speech and communal law. He is fully committed to "spreading the signal" of his radio station to anyone who will listen; it's his duty to counter the propaganda spouted by the Enclave on their station.

At some point before he established GNR, he was taking Jet and stumbled across Oasis. He established GNR in 2272, together with Margaret. Since he began, he's been broadcasting to the Wasteland with public service announcements and music. At times he makes jests at Enclave Radio, going as far as mocking President John Henry Eden's voice.

Three-Dog believes in what he calls 'Fighting the good fight', which boils down to noble pursuits in the fight against raiders, super mutants, slavers, Talon Company, and the Enclave. This explains why he cooperates with the Brotherhood of Steel. However, he does not do any physical fighting nor does he help to coordinate or organize it.

Daily schedule
He stays in the GNR Building Plaza throughout the entire game.

Quests

 * Following in His Footsteps: Passing a speech check will give you immediate information about your father.
 * Galaxy News Radio: Failing, or not taking the aforementioned speech check starts this side quest. If you pass that speech check, you can immediately reinstate conversation to have both quests running up at the same time. You can also come back later, or see him for the very first time after having made progress otherwise in the main quest to find your father, and if you bring your support to his "good fight", Three Dog will also give you this quest.
 * The Search Continues: Killing Three Dog before he tells you to go to Rivet City at the end of the Galaxy News Radio quest starts this quest.

Effects of player actions

 * Three Dog will comment on various actions of the player through his radio broadcasts.
 * On Galaxy News Radio, Three Dog may refer to the Lone Wanderer by his/her current Karma title.

Notable quotes

 * "Now what if I, the all powerful Three Dog, bow-wow-wow, were to tell you that somewhere right here in the Capital Wasteland, is a place with lots of trees?"
 * "People of the Capital Wasteland, it is I, Three Dog, your ruler! Hear me, and obey! Oh sorry, that's that other radio station."
 * "Hey nifty America, it's me, your President John Hen-- Hahaa, gotcha! Three Dog here, how's everyone doin'?"
 * "That's right, from Megaton to Girdershade, Paradise Falls to the Republic of Dave, we're coming to you loud and proud in a special live report."
 * "The Enclave, and that includes their homecoming king, "President" John Henry Eden and his gorilla, Colonel Augustus Autumn, are NOT here to help you."

Behind the scenes

 * The name of the character Three Dog comes from a previous character played by his voice actor Erik Todd Dellums, called "Dog 3".
 * Three Dog shares similarities to very many DJ characters from movies and real life, Wolfman Jack chief among them.

Bugs

 * Occasionally, Three Dog will mention events that occur after the ending of the game. He will only do so if the player had downloaded the Broken Steel downloadable content and has not played through the part in the game before it.
 * Sometimes after starting a new game, Three Dog can be heard stating things that haven't come to pass yet. This can be very annoying as it usually lasts the entire game or until you catch up with what he's talking about.
 * Sometimes Three dog will start saying a comment and then quickly switch comments about the player over and over again. This can be annoying and not allow you to listen to music for the rest of the game.
 * Occasionally Three dog will repeat the "News" section of broadcast 2-3 times over until he will continue playing songs again.
