Did you know that a dog’s sense of smell is on average 10,000 to 100,000 times superior to that of humans? Dogs have over 200 million scent receptors in their noses versus humans who have only 5 million. If you were to unfold and spread out the membranes from a dog’s nose, they would be larger than the dog itself.
Scientists have recently discovered that dogs can actually smell the presence of autism in children. A 2006 study found that dogs could also positively identify breast and lung cancer with 99 percent accuracy. It’s not clear whether it’s smell or some other sense that Seizure Alert dogs use to alert their humans of an oncoming epileptic seizure. Whatever the reason, we're glad our canine companions have such a keen sense of smell!
