Dogmeat is also a special non-player character who can be located and recruited in Fallout 2. He can be found in the special encounter "The Café of Broken Dreams", though this is an easter egg and should not be considered canon.
He is incredibly effective in combat, as he can do three medium to high damage attacks per turn, and has the same number of HP as a full-grown man. However, one should think carefully before getting him to follow them. He will become a follower, but will not behave like other non-player characters in Fallout, 玩家無法和牠进行有效对话，无法让牠离开或等待，也不能向牠指示攻击方向或攻击对象。如果你想甩掉牠，除了让牠去死别无他法。
Dogmeat can be obtained as a follower in both games regardless of the player character's Karma.
Unlike humanoid non-player characters, Dogmeat cannot wear armor, equip weapons, or use items, although he can be administered stimpaks by the player character and has a Damage Resistance & Damage Threshold equal to that of leather armor.
Dogmeat is a reference to Mad Max 2 (aka The Road Warrior) and A Boy and His Dog. Both movies featured a lone wanderer and his dog-companion in a post-apocalyptic world, and in the latter movie, the main character uses "Dogmeat" as a disparaging nickname for his companion.
Phil confirms the point above when he describes Dogmeat's former owner in the original Fallout: "Oh, the guy was tall, dark-haired with a little graying around the edges. He was dressed all in black leather, like that's a good idea in the desert, and carried a shotgun." The description matches all of Max's characteristics in Mad Max 2.
Scott Bennie was the designer who came up with the name "Dogmeat" for the in-game character. The name was initially applied to Jake's dog in the Hub (previously called Dogshit). Later, it was applied to the current non-player character Dogmeat, either by Tim Cain or Jason Anderson.
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.
