Resumen de Dogs really can smell your fear
Dog owners swear that their furry best friend is in tune with their emotions. Now it seems this sense of interspecies connection is real: dogs can smell your emotions, and adopt them as their own. "The role of the olfactory system has been largely underestimated, maybe because our own species is more focused on the visual system," says Biagio D'Aniello at the University of Naples Federico II, Italy. However, dogs' sense of smell is far superior to ours. Dogs exposed to fear smells showed more signs of stress than those sniffing happy or neutral smells. They also had higher heart rates, sought more reassurance from their owners, and made less social contact with strangers.
