Dogs

We all know that dogs' senses are very agile, but do you know how agile dogs' senses really are? To put it simply, dogs’ sensory sensitivity is 1 million times that of humans. A trained dog can distinguish more than 10 different smells. Isn’t this hard to imagine?

Feeling is very important for dogs. They can use sensory information to identify their owners, check whether there are intruders on their land, whether there are dogs around who are not "showing love", and identify the direction. , looking for prey, etc. If you carefully observe the daily life of dogs, you will find that they often judge physical objects through feelings. When traveling far away, they will even try to inhale as much gas as possible to help them make assumptions.

The reason why dogs’ senses are so sharp is that they have a larger area of ​​olfactory mucosa. The olfactory mucosa is the sensory organ of most mammals. The total area of ​​​​the human olfactory mucosa is only about four times that of a dog. 1 in 1, so it makes sense that dogs feel more agile than people. The dog's keen sense reflects two aspects: sensitivity to smell and the ability to distinguish smell. When we don’t feel the smell coming, dogs are already able to react in certain ways; and when people are still struggling with several similar smells, dogs have already smelled the difference.

Because dogs have extraordinary senses, people use this to train police dogs that can detect information. The sensory agility of well-trained police dogs can be 10 million times that of humans. Even if you put them 120 kilometers away, they can still find their way home through their senses.
