An affectionate and dextrous dog, Dogmeat's skills as a four-legged scavenger and ferocious fighting companion were not lost on his first master, who was recently killed by raiders in the vicinity of the Capital Wasteland scrapyard. Dogmeat has tracked the raiders down, loyal to the end.
The following is based on Fallout 3 cut content and has not been confirmed by canon sources.
Before the release of Fallout 3, the process of how to recruit Dogmeat had only been shown as a small clip as the Lone Wanderer holds something out to the wounded dog. The item is not revealed. Dogmeat was said to be found in a random encounter, which would appear in different places depending on where the player ventures to, but was meant to appear early on to help develop the character's bond with the dog. This was scrapped in the released game.
End of information based on Fallout 3 cut content.
Dogmeat is modeled after the dog in Mad Max 2 (aka The Road Warrior). The main character Max, played by Mel Gibson, had a dog that wandered with him. Dogmeat is the same breed as Max's dog, an Australian cattle dog.
The namesake for "Dogmeat" is Vic's canine companion "Blood" (also called "Dogmeat" by Vic) in the movie A Boy and His Dog (1975) starring Don Johnson and based on the novel by the famed sci-fi author Harlan Ellison. This movie dealt with post-nuclear war survival with "Dogmeat" apparently conversing with Vic as they both scour the wasteland for food and women.
