The News Minute | February 18, 2015 | 06:34 pm IST  Often considered man’s best friends, dogs don’t just make friendly animals, but are also known for their keen sense of smell.  We may have seen dogs been employed by the police or the bomb squads in investigations, but to what extent does a dog’s nose drive it?  Dogs are said to understand, interpret and experience the entire world through their sense of smell, just like human beings depend on their sight.  A video, titled How do dogs "see" with their noses?, recently released on Youtube by Ted-Ed tries to explain how dogs see the world through their noses.  When we see something in a single moment, a dog sees it as an entire story from the beginning to the end, states the video.  A dog’s sense of smell is so powerful that it can not just smell different things together at the same time but can also identify their location or source of the smell.  Dogs have around 300 million highly specialized olfactory receptor cells- compared to which human beings only have 5 million of those. Dogs can also smell things that can’t even be seen at all. They possess a set of olfactory system called the Vomeronasal Organ which helps them detect the hormones animal and humans naturally release. They can also detect emotions and tell when some one is sick or pregnant or if an animal is friendly or hostile. Watch the full video here to know more.  Tweet Follow @thenewsminute
