Can confirm Wolves don't, I just landed with a boatload of them. I haven't brought any Lox over however.

I'd say just to be safe (especially with the Lox) not to damage any Dverger structures as Lox will tend to trample them a bit, could potetially piss them off on accident.

Also with the Wolves. Try to put some campfires down to prevent hare spawns as they might give chase & accidentally attack the dverger structures too. Good luck with however you proceed.
