True, but for fire alarms, one should have an "off switch"-type command their dog knows, as false alarms are common both in the home and in public. I don't know if they do train this, but I should hope so.
But, some people may want to know an alarm is a possibility ahead of time so that they can be prepared for it. Some may choose not to go in because they don't want their dog exposed.
Guide dogs are trained to have intelligent disobedience. For example, if the human doesn't hear any cars coming so tells the dog to go forward so they can cross the street, but the dog sees a car coming, the dog will not move.
That is exactly what I am talking about. A SD working with a blind person is trained to not follow a command if it would put the person they are working with in danger. Another example would be if the dog has been told to go forward, but sees a danger like a hole in the pavement that the person needs to be guided around.
In the situation of some of the things in Innoventions, the dog may be being told to go against their intelligent disobedience training - i.e. keep going into a situation that the dog perceives as dangerous and would help the person to avoid in real life.
Some people may not want to expose their dog to a situation like that either.
The situation of not obeying commands I was thinking of in particular when I talked about someone having to 'talk' their dog into obeying was a blind college student whose dog was trying to get her to go across the street when the person wanted to turn at that corner. The dog was following the usual path to get to the first class of the day and the student was trying to skip her first class to go for coffee with friends.
Service dogs are not allowed to be protective in the sense of aggressive, though. They must allow things like EMTs to work on their human in an emergency.
There are 2 possible reactions to a perceived threat.
One would be FIGHT or aggression (which we have been warned to watch against and not allow in DD's dog). I would not expect that from a SD unless someone was coming at the handler with a gun or something potentially lethal!
The other response is FLIGHT or in this situation, the dog wanting to remove the person from the danger. That was the reaction I was talking about. It may not be a comfortable situation for either the dog or the person if the dog sees everything in the pavilion as something he/she
should be helping the handler to avoid.
Re-looking at the WDW information in the Guidebook, I think it's probably more like all their other warnings. It's up to you to decide it the warning applies to you. So, if the individual SD team has concerns, they would be warned in the book to contact the CM and ask. That might be more what they were getting at.
