Dogmeat is a German Shepherd Dog living in the Commonwealth in 2287. He will be named Dog until the Sole Survivor speaks to Mama Murphy about his true name during When Freedom Calls, or until Nick Valentine reveals his name during Getting a Clue.

A typical Commonwealth canine, Dogmeat is capable of tracking a man's scent for miles. While he doesn't have a real owner, he is a faithful and loyal companion to those he accompanies.

During the time that the Sole Survivor was cryogenically frozen in Vault 111, Dogmeat assisted Nick Valentine on a number of cases, and also accompanied Preston Garvey and his group of settlers on their way to Concord. When the group was ambushed by raiders, Preston sent Dogmeat to search for help in nearby Sanctuary Hills, patiently waiting at the Red Rocket truck stop for someone to come along and lend a hand.

When the Survivor arrives, they can choose to adopt Dogmeat, who will accompany them on their travels throughout the Commonwealth. Dogmeat's remarkable senses and tracking abilities come into good use when the Sole Survivor searches for Kellogg.
