This Cool Video, a 4.5 minute Ted.ed talk by Alexandra Horowitz, the explains the power of a dog's sense of smell.  Canines developed an olfactory sense that is a hundred million times more powerful than a human's.  They can smell in stereo, as it were.  It appears they can also smell the past, at least for a little while.  Dogs can smell the pheromones that animals, including humans, produce. Some can detect pregnancies and different types of illnesses.
