A Brain's Best Friend

A Brain's Best Friend is a side quest in the Fallout: New Vegas add-on Old World Blues.

Quick walkthrough

 * 1) Try to find a trace of Gabe in Higgs Village.
 * 2) Find Gabe's bowl behind what used to be Dr. Borous's house.
 * 3) Return to Dr. Borous.

Detailed walkthrough
Begin the quest by going to Higgs Village. When you first enter, your objective is the house to the left on the far corner; House #103. Behind the house is a doghouse with "GABE" spelled out below it, on the mat, along with Gabe's bowl which you must now take. A note must be made that if the player has taken the Wild Wasteland perk then a unique deathclaw named Stripe will be inside the doghouse, this can be problematic so caution is advised for retrieval of the dog bowl.

Proceed to the X-8 Research Center and go through the main quest line for this area, X-8: High School Horror!, till you reach the Residential Test Facility part of the quest. Once there you must kill Gabe to complete this stage of the questline.

This quest can still be completed if the player had killed Gabe prior to aquiring the quest.

Once Gabe is dead return to Dr. Borous and give him the Dog Bowl, he will reminisce about his dog and thank you for killing him; as he believes it saved him the trouble. However you may also pass a 45 speech check and make him feel remorse for the horrid experimentation he did to Gabe.

Behind the scenes

 * The quest name is a probable nod to the saying that "A dog is a man's best friend".
 * Or from the 1993 film 'Man's Best Friend' in which a mechanized dog has to be put down, violently.
