That's why I don't take them. I get attached and don't want them to die.
Dogmeat followed me straight to my house in Megaton, and he has lived there ever since.
I had FO3 on PS3 as the GOTY edition and Dogmeat was damn near invincible, so when I got the vanilla edition on Xbox I freaked out when he got shredded to pieces and reloaded. He now faithfully guards Vault 101.
If I wore panties, I'd need to change them! ~VexNoFace
