I hate to break it to you but dogs do not experience guilt. The old “go to your room without supper” routine does not work any better with dogs than it does with children. Blaming us because we ought to know better is absurd. If dogs knew better, we wouldn’t have done it in the first place.
As a practical matter, all you can do is ignore the deed and learn from the experience to teach your dog what they can and can’t have. “After the deed” discipline is not only ineffective, it undermines the relationship you are trying to build and causes us to distrust you.
