A dog's sense of smell is an interesting phenomenon. Did you know that it is ten to a hundred thousand times stronger than the human one? That is why our four-legged friends are often used in important tasks, in which they can even save lives thanks to their sensitive nose. They are used, for example, as military dogs that can sniff out the presence of bombs, but also as assistance dogs that can warn their master suffering from epilepsy about an impending seizure or a diabetic when his blood sugar level drops too low.
Even if we shower daily, smell perfumes and antiperspirants, we cannot hide our typical smell from the dog. In the same way, a dog gets a lot of information about another dog by smell. That's why they often "greet" by sniffing their bottoms. They can supposedly tell what they ate or how old they are. This is also one of the reasons why furry people often mark their surroundings. They share information about themselves and communicate with each other. In short, even dogs have their own Facebook.
DOGS FEEL HUMAN EMOTIONS AND DISEASE
It probably won't come as a surprise to you that dogs can perfectly sniff out your lunch. Even a hundred hunts away. But they smell much more than just food, another animal or even a fish. He also feels your emotions. If you're scared or sad, the furry one will know because of your adrenaline level. He will also know that you are afraid from the increased heart rate and sweat production - his sensitive nose will alert him immediately. That's why they are often used as assistance dogs, who can sense the beginning of an anxiety attack in advance. Allegedly, they also recognize serious diseases based on symptoms that cannot be detected by the human eye or smell, such as cancer. And you certainly didn't miss the fact that they can also smell the presence of the coronavirus.
THE SENSITIVITY OF THE NOZZLES DIFFERS
Dogs have millions of olfactory receptors hidden in their snouts - but the numbers vary, and the size of the dog doesn't matter as much as many might think. For example, dachshunds have approximately 125 million olfactory receptors, while Bloodhounds boast more than twice that number, and are therefore most commonly used for hunting tracking. German Shepherds, which are popular with the police, have approximately 225 million olfactory receptors. By comparison, the human sense of smell contains only five million of them.
DOG'S SENSE OF SENSE AS AN INTELLIGENT MACHINE
Dogs have a stronger sense of smell than humans because their noses are structured differently. Their respiratory system also works differently. For example each of the dog's nostrils contains separate openings for breathing in and out, and they also function independently. This means they can pick up a variety of odors that come from different directions.
When your dog sniffs you again or greets his canine friend, imagine the amount of information he is getting. Too bad he can't tell us.
