Scientists tease a dog and call it research!

They then reprimanded the dog to produce a “sad” reaction, causing the animal to pull a mournful expression with eyes cast down. Surprise, generated using a jack-in-the box, caused the dog to wrinkle the top of its head into something akin to a frown. Medicine that Mal did not like was produced to stimulate disgust – flattened ears – and nail trimmers, which Mal also disliked, were brandished to create fear, causing the ears to prick up and the whites of the eyes to show.
