Dogmeat (Fallout 3)

Dogmeat is the dog companion of the Vault 101 Dweller. His name is a homage to the Dogmeat from the first Fallout and according to the developers, he's the descendant of Vault Dweller's original canine companion that died in a horrible accident involving a force field.

Dogmeat is said to possess lifelike AI and has many uses in wasteland survival. His main combat use, apart from minor damage, is distracting the character's adversary giving him/her an opportunity to establish an advantage. It has been stated several times by Bethesda that Dogmeat can also be used to fetch supplies that are very necessary in the post-apocalyptic wasteland. Another important note is that although Dogmeat can follow you to all ends of the Earth, he is mortal and can be killed in battle or even when acquiring materials in a dangerous territory. If he dies he will stay dead, obviously imitating reality.

The process of how to recruit Dogmeat has only been shown as a small clip as the Player holds something out to the wounded dog. The item is not revealed. Dogmeat is found in a random encounter, which will appear in different places depending on where the player ventures to, but is meant to appear early on to help develop your bond with the dog.

Appearances
Dogmeat, while named just like the one from Fallout (which was said to die in a military accident), is a new character that appears only in Fallout 3.
