Solve Phil's Canine Conundrum

Solve Phil's Canine Conundrum is an unmarked quest in Fallout.

Detailed walkthrough
To start this quest, the Vault Dweller needs to go to the Casino area of Junktown. To the right of the entrance area, there is a pair of people trying, unsuccessfully, to enter their house. The reason they cannot enter is that Dogmeat is blocking the door.

Simply wearing a leather jacket (which will remind the dog of its former master) or giving the pooch some iguana-on-a-stick will solve the quest and let the couple enter their house.

Rewards
