I fostered a very smart dog at one point and came away a bit spooked, honestly. If you were hanging out with someone it didn't trust and said that you were going to the restroom, it would immediately walk into there and wait for you, and it could tell the difference between time concepts like 'soon' and 'later'. We never had any real problems with it, but the sense that it listened, understood, and did not speak back was unsettling.
