Faithful Protector

Faithful Protector is a companion perk . 
==Requirements==
Gaining this perk requires talking to Doctor Henry during Nothin' But a Hound Dog about replacing Rex's old brain with a new one and following the option of visiting Old Lady Gibson at the Gibson scrap yard where she lives with several dogs, including Rey.
To obtain Rey's brain, the player character can:
* Murder Rey. Doing this without being hidden will turn Gibson and her other dogs hostile.
* Pay 700 caps after which Gibson kills the dog herself and gifts the brain.
* Pass a 70 Barter check to bypass the caps and get the brain for free.
==Effects==
When Rex is an active companion, he gains a bonus of 25 points to damage dealt with his bite "weapon".
==Notes==
The attack damage effect is applied via scripting attached to Doctor Henry's dialogue instead of a perk.
