Ok, so I chose the vampire side of dawn guard and immediately got to where I can have a hell hound follower.... But the first one died on me, cause there was a slight issue with a dragon, but its gone now... So I got another one.. And had another incident with a dragon... But now I can't find any more so I was wondering if there is another hell hound just hiding somewhere, or if I did indeed manage to kill the only hell hounds you can get. Thanks!
