Dogs can smell when you’re stressed

Dog PicNo wonder dogs have earned the title of “Man’s Best Friend.” A new study says canines seem to have the ability to know when people are stressed.

According to an article published Wednesday in the “Plos One” Journal, dogs appear to be able to smell when someone is stressed. Previous studies have already confirmed dogs can tell when a person is scared or happy, so for this round of research, those competing scents were eliminated.

The findings are based on 36 people whose breath and sweat samples were collected during and after performing a task. The dogs got the right emotion nearly 94% of the time.

Our four-legged friends have 220 million olfactory receptors, which more than quadruples the amount that humans have.
