I don't recall that it was ever a problem in DD. Dogs eventually got annoyed with me... something about my killing the wolves that attecked me, which was irksome because I like dogs... but that was about it.
With BD every blasted step in every blasted map has the potential of stepping on a neutral creature and instant hostility. It is THE single most annoying feature in a game peppered with annoyances. It's not an exaggeration to say that I've reloaded well over a hundred times in the first two acts due to accidently turning neutral creatures hostile. I'm just about ready to throw role-playing out the window, scream "screw it!" and massacre everything I see just to get them the hell out of my way.
