Man's Best Friend

Man's Best Friend is a Fallout: Brotherhood of Steel skill (skills in this game work like perks do in other Fallout games). It was also going to appear in the canceled Fallout: Brotherhood of Steel 2.

Effects
You acquire a canine companion to aid you in your battles named Dogmeat. It appears for the first time when you reach a save point.

Behind the scenes

 * The Vault Girl version of the Man's Best Friend skill can be seen in a TV for educating cyberdogs in the X-8 research center at the Big MT in the Fallout: New Vegas add-on Old World Blues.
 * 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.
