Dogmeat and Houndoom. lol
i am so going to use Dogmeat next playthrough!
Use it. It's a memorable name, though I've never been quite sure of the original meaning.
This is the only time a game's let me choose a dog's name and no name came to mind but Dogmeat. The only canine companion I've had in a game - Fallout (well, except for K-9, the robodog in Fallout 2).
