To understand why dogs are so incredibly gifted at sniffing out medical conditions – not to mention drugs, explosives, lost humans, and, of course, cats – you have to fully appreciate the wonder of the canine nose.
Your average family dog has a sense of smell 10 000 to 100 000 times more sensitive than any human. They have 300 million olfactory receptors, compared to our measly 6 million. Scientists have likened their ability to “catching a whiff of one rotten apple in two million barrels.”
And these facts just barely scratch the surface of what dogs’ remarkable snouts are capable of. From law enforcement and military employment, to laboratory medical research, the power of the canine nose has helped save countless human lives.
Dogs all over the world are currently putting their noses to use detecting these six medical conditions in humans. In doing so, they improve and prolong the lives of the people they serve.
