In my current attempt at nethack I'm playing a dwarven samurai with a dog pet, so most dwarves I've encountered are peaceful. However, for some reason, my dog has been going beserk on every friendly dwarf we meet and I'd like to know why.
Since this doesn't really incur penalties on me, not to mention he was getting experience, I didn't mind it while going down the gnomish mines, but now it's becoming a problem. I've just reached Minetown and imagine my surprise when my pet decides to attack the owner of the first shop I visit. Though this still incurs no penalties, I'm afraid he's going to get zapped to death, so I have to lock him out of every shop I visit.
Now I wonder, did I do something wrong that is causing this?
I didn't catch any message like "Rex is confused with hunger." or something (plus, I almost starved because he was pouncing on every single corpse we made).
I've heard you can train your pet to steal by feeding him when he drops you stuff, is it somehow possible that I have accidentally trained him to be aggressive?
