Bugs

 * In Little Lamplight, if Dogmeat is following you and you go into the testing chamber to explore, Dogmeat may appear dead while exiting. Then while leaving a room or house, Dogmeat's dead body will spawn outside next to where you entered. Dogmeat may or may not take up a character slot after dying this way. Dogmeat will also still be shown blinking. This also can happen to Jericho.
 * During the Blood Ties quest Dogmeat may disappear from the game after talking with Vance about making a deal with Arefu. Loading a previous save doesn't fix the bug.
 * The game might crash if you try to talk to Dogmeat while the battle is still ongoing in the Scrapyard.
 * Through the use of the Paralyzing perk (or any weapon with a knockdown effect), Dogmeat can store items whose weight total exceeds 10,000 lbs. However, asking him to fetch you an item at any time will return all stored items. If you ask Dogmeat to return to Vault 101, you can pickpocket him and store items too.
 * Dogmeat's inventory can be accessed any time after he has been told to "Go wait by Vault 101," simply by a standard pickpocket maneuver. The game will treat Dogmeat the same as any NPC who is pickpocketed, so the player character can be caught. This will temporarily block from re-attempting accessing his inventory but can be completely avoided by saving and reverting. This may result in a karma loss.
 * Despite being sent back to Vault 101, Dogmeat has shown up inside of the West residence in Arefu. After going outside, Dogmeat does not follow.
 * Dogmeat has appeared in Pilgrim's Landing during the quest Thought Control.
 * Attacking Dogmeat until he becomes hostile and then putting away your weapons will result in Dogmeat walking back to Vault 101.
 * After leaving Vault 101 for the first time, Dogmeat can be found outside, sometimes clipping into the ground. If interacted with, no dialogue options will appear and will not be recruitable as a companion, even if the player goes to the scrapyard.
 * If the player character kills an enemy while Dogmeat is attacking them, he will not notice that the enemy is already dead and keep attacking the corpse even after it is mutilated.
 * Dogmeat can be brought to Point Lookout by having him search for an item just before sleeping on the cot in the Duchess Gambit. He will approach the player in Point Lookout after six days. He can be returned to the Capital Wasteland simply by taking the Duchess back, resulting in him automatically waiting at Vault 101. This may not work until Nadine has control of the Duchess.
