We presumed that at some point owners would pop out of the house, to take out the bin or go to the garage etc.. Such leaving events are likely to be experienced differently by some dogs, as the owners won’t likely give off the same cues as when they leave for an extended period of time, such as picking up house keys, or leaving through a different door. This has been explained now in lines 179-83.
This Figure should be moved to the Supplement material as it tells nothing about the dogs’ behaviour.
