Kill the Devil Dog

Kill the Devil Dog was going to be a quest in Van Buren, the canceled Fallout 3 by Black Isle Studios.

Background
Devil Dog is a mutant dog worshipped by the Blackfoots.

Walkthrough
The Hangdogs want you to either tame or kill him, although they would rather see him killed. Killing him will give the player the Devil Slayer reputation. Rather than taming him, you can just kill him. The kill needs to be reported to Bares His Teeth.
