Don't guide dogs respond to stimulus? A car in the road means stop? Not wilful disobedience at all. It would be if it hadn't been trained to stop it's human from walking into traffic. Just responding to cues, right?
Wayne, I can't speak for Alice (Lord knows the woman can speak for herself) but some do not want a dog to have willful disobedience. There are many situations and jobs that do not allow for this. The dog does not get to pick and chose over whether or not to obey a given command. The command is given, the dog must obey. This is very important depending on the job the dog is tasked with. For guide dogs, yes, the dog must have some latitude with their job. For law enforcement canines there is less wiggle room. If the dog is sent to engage an individual, the dog MUST do that. This isn't a democracy. The dog doesn't get a vote.
