Confused husky pup
He’s not expressing confusion, he’s tilting his head for better sound localization. While having an ear on each side of the head is good for lateral echolocation, tilting the head so that the ears are offset gives it vertical depth.
Fun fact: if you approach an employee and insist that they go ‘check the back’ for an item that’s not on the shelf, there is a 90% chance that they’ll go to the back room, scratch their ass and check their text messages for five minutes, and come back out with a sympathetic smile and a ‘Sorry!’ because they know without even looking that the stock isn’t there.
Or the old “can you ask a manager?”
