You won't be seeing puppies in the movie Seven Psychopaths…because they can empathize with you!
Dogs catch the yawn bug, just like humans, chimps, and baboons, and yawns are known to be great measures of empathy.
But, when it comes to dogs, yawning is something they LEARN, after a certain point in their puppy-hood.
In the study, the scientists played with 35 puppies (BEST EXPERIMENT EVER!!!!), aged four to fourteen months. They yawned in their faces and they saw that puppies younger than seven months really didn't do anything.
In fact, half the dogs that did yawn almost fell asleep! LOLz!
Concluding the study, the researchers were able to match the puppy yawns with human development. Kids tend to catch yawns around the age of four, when they can begin recognizing other people's emotions.
So don't mess with kids under four or puppies under seven months! HA!
