Help Phil Get Rid of the Dog

Help Phil Remove the Dog is a side quest in the Fallout demo.

Quick walkthrough
Phil asks the Vault Dweller if he can help with removing the dog in front of his shack. The Vault Dweller has two options in doing this, recruiting it as a companion, or killing it.

Detailed walkthrough
There are two ways to complete this quest:

Recruit the dog as a companion
There is only one known way of completing the quest without killing the dog, and that is by giving it some iguana-on-a-stick. Some can be found in the player's inventory, or in the locked fridge that the Crypts guard. Once given, the dog will follow you and help you in battle. Phil will warn you about the dog saying that it is a killer, and you will gain 550 XP.

Kill the dog
There are many ways to kill the dog in the demo, but the most quick and efficient way would to get close to it, open up VATS, and hit it with a burst shot from the Vault Dweller's H&K MP9 10mm SMG. Phil will be grateful that the dog is gone, and you will receive 335 XP, a bit less than completing it the other way.
