Scents and Sensitivity: Dogs Know When We're Happy or Angry

Science is proving what pet owners have long believed


Dogs understand what we're feeling. Specifically, dogs can recognize the difference between a happy and an angry human face, a study published Thursday in Current Biology suggests.

In the Austrian study, 20 pet dogs of various breeds and sizes were taught to play a computer game through a series of exercises. In the first, the dogs were shown two touch screens, one with a circle and one with a square. Through trial and error, they learned that a treat would appear if they chose the right geometrical figure.

Eleven of the 20 dogs were able to catch on to rules of the game and make it to the next phase, where they were shown photos of faces. Half the dogs were rewarded for picking a happy expression and half for choosing an angry expression. The interesting catch: the dogs were shown only the upper half or the lower half of a face.
