Dogs to debate their identity through mutual smells
For dogs, the nose may be one of their most important organs, because the dog's vision and smell are not very good, so many times the dogs rely on "sniffing" to judge the taste of food and recognize the way. Essence As for how sensitive the dog's smell is, I believe it is no need to say more. Their sense of smell is more than 1,000 times that of people, so even if it is quite subtle, they can smell it by nose. It is precisely for this reason that dogs can rely on their noses to end a lot of things.
Recently, an interesting news appeared. One owner felt quite interesting because he saw other dogs on the Internet that he had the ability to identify money, so he began to train his dog how to identify money. The training is also quite successful. Whether it is at home or on the street, as long as the owner's money is dropped, the dog will help pick it up and hand it in the master's hands. And after long -term training, dogs are now very sensitive to money. One day the dog became uneasy next to the sofa at home and smelled everywhere, and he refused to leave. Because the owner felt strange, he set off the sofa cushion and found 300 yuan hidden inside. Not only that, the dogs also found the hidden money in many places at home, and finally learned that the money was actually the private house hidden by his husband. money.
Anti-Drug Dog
This case is not only interesting, but also shows how well the dog's sensitive smell is excellent. It is also so that dogs will be trained to complete various tasks. The dog's nose can argue about 2 million different odors, and there are quite excellent analysis ability. They can smell the smell it wants to look for from many mixed odors. The nose structure of various types of animals is roughly the same. There are many folds on the upper part of the nasal cavity. There is a layer of mucus film on the folds. Many olfactory cells are hidden in the mucous membranes. When the mucus secreted on the mucous membrane often wets these olfactory cells, it will make the smell smell The material molecules are dissolved in mucus and stimulated the olfactory cells. The olfactory cells immediately sent a signal to the brain's olfactory center, so they felt "taste".
The reason why the dog's sense of smell is so outstanding because it has a lot of smell cells. Even the nasal mirror part has many protrusions, and there are mucosal tissue. It can often secrete mucus and moisturize the olfactory cells and keep it highly sensitive. The number and quality of dogs' olfactory cells are better than other animals, so the ability to identify all kinds of odors is much stronger than other animals.
It is precisely because of the sensitive sense of smell that dogs are trained for various occasions, such as post -disaster search and rescue, anti -drug investigation, harmful security inspection, and so on. Of course, you can also use this feature for some interesting purposes. For example, the search for private house money mentioned earlier is one.
Search and Rescue Dog
Dogs usually rely on the nose to distinguish each other's identity, and find the labels they have done all the way to determine which road to go. And it is said that dogs can judge a person's mood through a sense of smell and make a reaction. There are also many examples that dogs can smell whether people's bodies have some lesions to remind patients. Therefore, there is also the position of Dog Dog, but the accuracy of the judgment of the disease is not particularly high, and there are not accurate, so many people are doubts about the statement of dogs that can smell the disease.
Dogs' sense of smell is very important for them. If a dog's sense of smell has a problem, then the inconvenience to their lives is unimaginable, so it must be protected. Do not take some irritating scent gas to stimulate the dogs. When you get along with your dogs, do not spray perfumes such as perfumes. Keep ventilation indoor to avoid excessive dust.
