Dog/God is glitched i cant talk to him both personalities just say let dog out
then when i have gathered everyone at the fountain elijah thinks i only recruited two of them so i cant continue the game
ive tried reloading the game and re-recruiting dog/god several times i even tried playing the dlc on my old character it always ends up glitching the same way

any ideas?
thanks

I am having a similar problem I have all three and the hologram of elijah at the foundation does not say anything. I know he is suppose to; however, i'm stuck. I've tried starting from a previous save but nothing changes and I have switched companions and switched between god n dog. Nothing works. I playing on the xbox 360 slim but at this point and time I want my money back for the DLC. I also ran into the another glitch where the collar will not stop beeping in the kitchen in the casino during the put down the dog quest. I have played through this DLC way two many times and it keeps glitching.

Same here and crap full of other bugs, Thanks Bethesda Softworks you guys are the the best

They are pretty awesome huh?

Anyway... there's a fix posted in the "Help With Dead Money" thread that's pinned/stickied.
