Junkyard dog

The junkyard dog is a character appearing in Fallout 4.

Background
The junkyard dog appears to be a Rottweiler, which can be bought from Gene, her current master.

Other interactions

 * If bought, the junkyard dog can be sent to any workshop settlement, and will count as 5 points of defense. She will also go into a doghouse to rest just like Dogmeat.
 * The junkyard dog can be found during a random encounter following Gene, her trainer. Gene will offer the junkyard dog for 250 caps, but the Sole Survivor must be able to pass a Charisma check of 6 or higher.
 * When looking to find the junkyard dog at the settlement selected when purchased, she will be found at any available Doghouse. One can remove all existing ones then place a new one where the player character prefers her to be located.
 * In the workshop interface the Sole Survivor can select/move the doghouse and she will follow around while carrying it.
 * Unlike with Dogmeat or settler NPCs you cannot trade with the junkyard dog, making it impossible to give her any dog armor or other apparel (unless done via console commands).

Appearances
Junkyard dog appears only in Fallout 4.

Bugs

 * If you have the "Animal Friend" perk, and aim your weapon at her, the option to "pacify" will appear which may result in her becoming hostile.
