    According to various existing surveys, puppies are able to perceive human diseases in advance, especially some cancers that are not easy to detect at an early stage. In addition, puppies are also able to sense the emotions of their owners. <>

    1. Perceptual disease:According to relevant statistics, there are about 5 to 6 million olfactory receptors in the human nose, and there are many odors that can be perceived, compared with more than 200 million olfactory receptors in dogs (there are certain differences in different dogs), that is, the sense of smell of puppies is 1 million times that of humans. When the human body has abnormal hormone secretion, the body odor is back to change, but this change or this smell is not within the scope of human smell, so humans can not perceive it, but dogs with a fairly developed sense of smell can feel it, so the dog may issue a warning at this time to remind humans.

    However, sometimes humans do not understand the dog's intentions and miss the earliest early stages of the disease, so the dog's ability to perceive the disease is not paid much attention. <>

    2. Perceived pregnancy:The secretion of estrogen after pregnancy is different from usual, so the dog can sense it at the first time and report the good news to the owner. There was once a news that a couple abroad found that the dog was particularly clingy recently, so they liked to rub around the hostess, especially interested in the hostess's belly, and the two suspected that something might have happened to them and hurried to the hospital, and the result was that they were pregnant.

    It can be seen that the dog's perception ability is really strong enough. <>

    3. Perceive emotions:When the owner's mood fluctuates significantly, the dog will immediately react to this: when the owner is happy, the dog will also have fun and play together; When the owner is unhappy, the dog will stay silently by the owner's side and show his concern with companionship.

    Dogs judge emotions by perceiving the owner's behavior and language attitude, and grasp the owner's emotions more accurately, so the dog actually acts according to the owner's face.

    Scientists explain that this is because cancerous cells produce volatile molecules that emit a peculiar odor when they enter the urine. The dog's nose has dozens of times the smell cells of humans, and the olfactory ability far exceeds that of humans, so it is not a problem to smell special smells.

    When humans are sick, the human body will release hundreds of volatile organic substances, and when the dog perceives that the owner is sick, it will do some abnormal behaviors, such as the originally gentle dog will bark at the owner for no reason, or be more clingy to the owner, never want the owner to leave, and will do everything to remind you. Generally, dogs' sense of smell is at least 1,000 times that of humans, and some special breeds are even tens of thousands of times more sensitive than humans after training. Dogs can also analyze and identify smells, which is why they can chase prey or work as drug detection and search and rescue dogs.

    For us human beings, we may only be able to detect illness through some external realization of our own physical condition, or the advanced technology of the hospital. But for dogs, the subtle changes in the human body can be sniffed by some molecules, which is why dogs can detect the owner's pregnancy or cancer at the first time, and the accuracy rate is as high as 70%.

    When humans get sick, the human body releases hundreds of volatile organic substances that smell almost indistinguishable to humans, but are very noticeable to dogs. When the dog perceives that the owner is sick, it will do some abnormal behavior, such as the originally gentle dog will bark at the owner for no reason, or be more clingy to the owner, never want the owner to leave, and they will do everything to remind you when they can't speak. Some specially trained dogs will make special movements to signal as soon as they notice that something is wrong.

    The human cancer cells will volatilize an abnormal smell, which will be keenly perceived by the dog, which is also the reason why some owners have just been sick, and the dogs at home will find that the owner is "abnormal", because the owner smells different from before.
