In February 2020, the overseas network reported a news that a 63-year-old man and his dog Heidi had an accident at sea, and the boat capsized and caused him and the dog to fall into the water together, but the dog tread water for 11 hours and "reported" to a passing fisherman.
After the fisherman found Heidi trapped in the water, he also saw a fishing tackle box and a wetsuit floating on the surface of the sea nearby, and guessed that there should be an accident nearby, so he immediately reported the incident to the police.
Brisbane Marine Police soon arrived at Moreton Bay, where the dog had been found, rescued Heidi, and then searched around by boat, and finally found a 63-year-old man in Moreton Bay a few hours later.
The man was still holding on to the boat that had capsized at this time, and the police rushed to help and finally rescued him, and after examination, the man was only slightly injured.
After Heidi was examined by the veterinarian, she was told that she was unharmed, and the staff of the police station arranged for her to reward her with delicious food and gave her the title of "honorary police dog".
Later, Heidi was reunited with her owner, and the man affectionately held the face of his dog, a scene that touched many people.
Dogs are known to be loyal and intelligent, and are one of man's most reliable companions, so can they really sense danger and save people from it?
«—[Clever Dog]—»
For example, in September 2021, Xinhua News Agency reported a news article in which 10 heartwarming stories of dogs saving their owners were listed.
For example, there is a golden retriever named Kelsey, who was out with his owner when he witnessed his owner break his neck in the snow and couldn't move.
It was freezing cold, and the owner thought that he would freeze to death here, but Kelsey lay on top of his master's body to keep him warm and screamed so hard that it took a full nine hours for anyone to find them.
At this time, the owner who broke his neck was already unconscious, and if Kelsey hadn't helped him keep warm for the past 9 hours, he would have frozen to death.
There is also a police dog named Meijer, whose intelligence is even more shocking.
Its owner is a veteran, and once the veteran had a seizure, Major didn't even shout, but stepped on the 911 police call with the owner's iPhone!
The police officer who received the call thought it was a prank, so he hung up the phone several times to Meijie, Meijie was not discouraged, it called 10 times in a row, and finally the operator realized that something might be wrong and rushed to the scene to save its owner through positioning.
This is really jaw-dropping, we know that dogs are very intelligent, but it is hard to imagine that it can be so smart that it is worthy of a well-trained police dog.
So how do they tell that their owners are in danger?
«—【Sensitive Dog·】—»
First of all, dogs have a very sensitive sense of smell, and they can even tell how the person is physically doing by smelling the smell of each other's breath and sweat, and of course, this is also how dogs communicate with each other.
So they can smell certain pheromones in the air, which is a chemical that can be released into the air by people or other organisms, such as when people are happy, the body secretes certain substances, such as dopamine.
When people are sad, the body will also release a lot of different pheromones, so for dogs, every emotion of people is "tasteful", this method of identifying problems through taste is very accurate, and dogs can rely on these pheromones.
Therefore, when a person is in danger, the dog can know what is happening and react through pheromones.
In this way, dogs seem to be born with an awareness of death and illness, and if they are trained to deal with such situations, dogs can easily become good helpers for their owners.
Of course, the IQ of different breeds of dogs varies greatly, and some of them may not have any special reaction even if they smell pheromones, but in general, most dogs are still very loyal.
Some of the more intelligent dogs can even tell if their owners are in danger by their facial expressions and body language, and dogs seem to be able to distinguish and deter bad actors.
So the dog has been until now, is one of the mainstream "darlings" of the pet market, people train it to care for the home or take it as a spiritual sustenance, and these dogs have not lived up to their mission, in many rescue operations have made great contributions.
So when did these lovely creatures come into people's lives?
«—[The long history of human and dog life·]—»
Some researchers believe that dogs were domesticated from wolves, but there is no evidence of how the first dogs entered human life.
By analyzing the differences between dogs and wolves, scientists believe that it would take at least 50,000 years for them to evolve such differences.
And as early as when people were still hunting for a living, dogs have appeared around people.
At that time, people kept dogs mainly so that they could help them hunt to fill their stomachs, and also to help with the care of the home. At this time, dogs were already very different from wolves, and scientists speculated that dogs should have intersected with humans long before that.
Dogs can hear 16 times more than humans, and even when they're asleep, they're alert to their surroundings, so it's perfect to keep them in the home at night when it's very dark.
After tens of thousands of years of domestication, many different breeds of dogs have emerged, and people have selectively cultivated them to differentiate more than 400 forms of dogs, each with different living habits.
For example, shepherd dogs that can "watch" the flock, sled dogs that pull sleds, these dogs can not only help people manage their daily lives, but also adapt to the ravages of bad weather and low temperatures, and are good helpers to be trusted.
Although the predecessor of the dog is a vicious wolf, but after a long time with people, they tend to show a more friendly state to humans, once they recognize the owner, they will willingly follow a master, no matter whether the food is good or bad, never leave.
Dogs are omnivores, and usually not only like to eat meat, but also all kinds of fruits, and if necessary, they will eat grass and drop some grass.
This is because dogs basically rely on their stomachs to digest food, and sometimes it is difficult for dogs to expel it smoothly when they encounter something that is not easy to digest, so eating some grass can just clear the stomach.
But it also has a lot of things that can not be eaten, such as food with a strong pungent smell, milk that people often drink, which will make the dog's nose and stomach feel uncomfortable, if the dog is smaller, you can feed goat's milk.
In addition, chocolate is also an almost unacceptable food for dogs, because chocolate contains theobromine and some purines, and the purer the raw materials for chocolate, the more likely it is to cause dog poisoning, so even if the living conditions are good, you can't feed the dog indiscriminately.
