So I got and idea for an event in wasteland when dweller find injured and when he pass charisma test he can use stimpak to heal him up and it will be chance that dog will follow him. When dweller will return with his dog companion player can choose to take him into vault or send him back to wasteland(super sad face (() In vault dog will be just cosmetic thing but when u will send dweller that found the dog to the wasteland u will have option to take him with you and it will rise his perception in wasteland +1. What you think about it?
