Which reminds me...
What is the collar supposed to do (or being used for), exactly? I don't remember ever finding any proper use for it except when I pressed a button that made it vibrate on one of the tower's floors. And I wouldn't really call that an useful discovery, anyway...
On the 3rd level of the tower there is a dispenser machine with a button in the corner of the room by the windows. Was meant for the dog to be automatically fed, so if you wear the collar it gives you something. I think in my last playthrough I got a bone, but some people mention getting a steak.
