Ghost people are difficult to kill unless dismembered or disintegrated. If Dog is in the party, however, Dog will devour them, preventing them from getting back up.”— Fallout: New Vegas description
When Dog is an active companion, he will consume ghost people that have been are knocked unconscious, preventing them from regaining consciousness.
- Technically this isn't a perk, but a scripted action only performed by Dog, hence it doesn't appear in the perk menu of the Pip-Boy or the G.E.C.K.
- After watching him devour a ghost person, the player can ask Dog how he keeps them down. This adds the Ghost Hunter perk.
