Using nose-activated vests and touchscreens, our canine pals are being trained to summon help for their handlers—and much more.

Imagine you’re enjoying a pleasant stroll through the park when you hear someone say, “My owner needs your attention! Please follow me!” You look around and see no one; then you look down and see a dog staring up at you. You think someone’s pulling a fast one. But then the dog reaches around and his mouth tugs something on the yellow vest he’s wearing, and you hear it again.

“My owner needs your attention! Please follow me!” the dog seems to say again, looking at you plaintively and now beckoning with body language for you to follow him. You do, and he leads you to someone who’s having a severe allergic reaction, a seizure, or some other medical emergency.
