How smart is your dog?
If you think your dog is smart – yawn. If your dog yawns too – that’s one smart pooch! Researchers at London’s Birkbeck College tested a bunch of dogs – and 72% of them were sensitive enough to yawn when seeing a human yawn. Contagious behavior like yawning suggests a rudimentary capacity for empathy – something scientist believed only applied to humans and chimps.
