Dogs identify each other by smelling each other
About dogs The nose is probably one of the most critical organs in their bodies. Since dogs’ vision and senses are not very good, dogs often rely on “smell” to infer the taste of food and find their way around. As for how sensitive dogs’ senses are, I believe it is needless to say. Their senses are more than 1,000 times that of humans, so even if they are quite small differences, they can smell them with their noses. It is for this reason that dogs can do many things with their noses.
An interesting piece of news recently emerged. An owner found it quite interesting because he saw other dogs on the Internet having the ability to distinguish money, so he On a whim, I also started to train my dog how to distinguish money. The training is also quite successful. Whether at home or on the street, as long as the owner drops the money, the dog will help pick it up and take it into the owner's hands. And after a long period of training, dogs have now become particularly sensitive to the taste of money. The dog became restless next to the sofa at home all day long, sniffing around and refusing to say goodbye no matter what. Feeling strange, the owner lifted up the sofa cushion and found 300 yuan hidden inside. Not only that, the dog also found hidden money in many places at home. Only then did he learn that the money actually belonged to his husband. Hidden private rent.

This case is interesting. It also proves how good the dog's sense of agility is, and it is precisely in this way that dogs can be trained to complete various tasks. A dog's nose can probably distinguish 200 different smells, and it also has a very good analytical ability. They can smell the smell it is looking for from many mixed smells. The structure of the noses of various animals is roughly the same. There are many folds in the upper part of the nasal cavity, and there is a layer of mucus membrane on the folds. Many senses are hidden in the mucous membrane.Sensory cells, when the mucus seeping out of the mucous membrane often moistens these sensory cells, it will cause the odorous substance molecules to melt in the mucus and stimulate the sensory cells. The sensory cells will quickly send signals to the sensory center of the brain, so there is " "Taste" feeling.
The reason why a dog’s senses are so good is because it has so many sensory cells. Even the rhinoscope has many protrusions and mucosal structures, which can Frequently penetrated mucus moistens the sensory cells, keeping them highly sensitive. The number and quality of dogs' sensory cells are higher than those of other animals, so their ability to distinguish various smells is much higher than that of other animals.
It is precisely because of their sense of agility that dogs are trained to be used in various situations, such as post-disaster search and rescue, anti-drug reconnaissance, obstacle security inspection, etc. Naturally, this feature can also be used for some interesting purposes, such as the exploitation of private rent mentioned above.
Search and rescue dogs
Dogs usually rely on their noses to make excuses Identify the other person's identity and look for signs of what you've done together to decide which path to take. And it is said that dogs can infer a person's emotions through feelings and then react. There are also many cases that dogs can smell whether there are certain lesions in the human body to warn the patient. Therefore, the position of dog doctor has also emerged. However, the accuracy of disease diagnosis is not particularly high, and there is no correct time. Therefore, many people are dubious about the idea that dogs can smell diseases.
Dogs’ senses are very important to them. If there is a problem with a dog’s senses, it will bring immediate consequences to their lives. It is difficult to imagine, so it must be well maintained. Generally, you should not use some irritating gas to irritate the dog. When getting along with the dog, do not spray perfume and other liquids with strong smell. Keep the room ventilated to avoid excessive dust.
