Rex is a cybernetic dog that has been around since pre-war times. He was used by the Denver Police Department and Caesar's Legion before being mostly blown up during the Battle of Hoover Dam. Since then, he's been the loyal pet of The King of The Kings in Freeside. Capable of sniffing out loot and taking a large amount of punishment, he only has one (big) problem: his brain is starting to deteriorate.

How to Recruit

When you've finished the G.I. Blues quest for The King in Freeside, you can move on to the Nothin' But a Hound Dog quest. For the second task of the quest, The King will send Rex with you to seek out a new brain.
