The dogs nose is an amazing organ, with abilities and features far superior to our own in many ways. First are the physical adaptations of the nose itself. The inside of the dogs nose is lined with many folds of tissue (called the olfactory epithelium), which in turn contain hundreds of millions of olfactory receptors, specialized cells responsible for detecting odors. Because of the increased surface area caused by these folds, the dogs nose contains a ridiculously high number of receptor cells when compared to the human nose; on average, the dog has about 220 million, while our noses harbor a paltry 5 million. This difference contributes to the dogs ability to detect almost impossibly minute concentrations of compounds, by some estimates in concentrations as low as parts per trillion.
