Ed-E was toasted in the gas explosion in the vault and I've been able to hook up with Veronica, Boone, and Raul since. But now when I try to take Rex along to fix him he won't come with me since he senses Ed-E with me! I've gone back to Primm to see if Ed-E has respawned but he's nowhere to be found. A known glitch that will doom poor Rex? Or is there some way out of this? Thanks...pray for Rex.

Try to travel to Vault 22.

Some chance Ed-E will be there, stuck inside? Thanks.

I guess I forgot that since Ed-E wasn't officially cut loose he's technically still with me!

try using the elevator in vault 22, it seems to bring back lost companions, on xbox atleast.

Rex can't be healed? IMO they should have used the original cut morphine animations (modified a bit) to allow you to heal the dogs by visually using a stimpak on them.
