'It is difficult for cats to come to the house, dogs come to the house', why?

I still remember the proverb that my father used to say since I was young: "It is difficult for cats to come to the house, dogs come home . " I asked again, why is that? My father only explained: "My village temple is dedicated to stone dogs, the revered humanity calls them Divine Or Shrews . " When I was growing up, I gradually understood that sentence, though not thoroughly, when I was studying the creatures and related science subjects.

1. Dog is one of 12 animals and is located in "ruminant" - 6 species of domestic animals: horses, cows, goats, chickens, dogs and pigs. Dogs are raised to keep the house or play. In Sino-Vietnamese words, dogs are called "crane" or "dog". Dogs are also called "civets", because they look like civets. All dogs, whether beautiful, elegant or powerful, have a common ancestor - like wild wolves. According to biologists, the first domestic dogs were domesticated from wolves 14,000 years ago, since then humans have bred, bred and produced thousands of breeds of dogs to adapt to climatic conditions. each region. Dogs can be very different in shape, size, color and personality but have in common: they all have 321 bones and 42 permanent teeth, like wolves.

Dogs are very loyal animals. Wolves that live in swarms so they have a special connection with the individuals next to them. This behavior is retained by dogs, instead of being loyal to the flock, the dog is loyal to the breeder. Stephen Zawistowski, scientific advisor to the American Society for the Prevention of Animal Abuse, said that when adopted, the dog will treat the owner as a member of his herd.

Among four-legged animals, dogs have a very good memory, the smartest type. While traveling far away for a long time, I still miss home - "lost my house in the dog, lost in the buffalo", so people taught them to become professional dogs and guide dogs. Scientifically proven, dogs can understand people's emotions. Previously, stories about a dog who understood the owner's feelings were often considered to be of no scientific value. But according to the latest study, psychologists from Lincoln University (UK) and University of Sao Paulo (Brazil) have shown that dogs can really understand people's emotions.

Specifically, these scientists have discovered that dogs can analyze the auditory and visual information they receive when exposed to humans and other individuals. They even have the ability to distinguish between negative and positive emotional states. The research team tested 17 different adult dogs, giving them access to emotional state information in two ways: hearing and vision.

During the experiment, these dogs were shown by the researchers to show images of human emotions, accompanied by sound clips depicting people's emotions corresponding to the picture. there. Occasionally, the emotional expression of the sound is in contrast to the image of the experimental object being seen. These dogs have never undergone any training related to the previous emotions, so the results have reached the most natural and natural level. Experimental sounds are Portuguese, a language that is alien to dogs so that they are not based on memories available in English. As a result, dogs always have a focus whenever they hear sounds that describe emotions that match the picture they are watching and they also show when they receive positive emotions, they stick their tongue out in a way. very excited, when receiving negative information like anger, they growled in a defensive way. If the picture and sound information does not match, they will bark a few hours to react.

Cats are not among the "rabbits", but because of their ability to catch rats well, every house raises and a good question, a smarter dog or cat? That question has worked. In December 2017, for the first time, scientists published a study on the brain size of these two species and also calculated the number of neurons in their cortex. Research results show that the average number of neurons in the cat's cortex is only half the average in the dog's cortex. Dogs have about 530 million neurons in the cat's cortex, only about 250 million. While in humans, the cortex has about 16 billion neurons.

Dr. Suzana Herculano-Houzel, Associate Professor of Psychology and Biology at Vanderbilt University, USA said: "Dogs have the biological ability to do more complex and flexible things in life than cats." Celia Haddon, a cat behavioralist, explains why cats have fewer neurons than dogs because "cats often have less social interaction." Dogs are the opposite, since the ancestors of dogs are wolves, species that hunt in colonies should develop more complex behaviors to work together. This is also the reason that dogs are very friendly and can easily cooperate with humans. Cats do not have such behaviors, because they only hunt by themselves and often live alone, " Haddon added.

Especially the auditory and olfactory parts of dogs are very sensitive: Dogs often lie on their ears and recognize distant noises, so they bark to protect themselves and warn their owners. Very good dog nose can sniff and differentiate the smell quite standard.

In a recent study, the German Becgie is on the list of the smartest dogs in the world. They become superior, when cancer can be detected with an accuracy of up to 100%. Specifically, Isabelle Fromantin, a project manager named Kdog, said that in just six months of training, a pair of German Becgie could recognize who is suffering from breast cancer.

Experts performed experiments on 31 cancer patients. These people wrap a gauze bandage at the breast area with cancer, then give it to the experts. The bandages are used as a tool to train two dogs, to train them to distinguish the bandages of cancer patients and normal people. After 6 months, they performed tests on 31 other cancer patients. Each bandage of the patient is matched with 3 normal tapes. As a result, after only 2 attempts, they can distinguish 100% exactly where the cancer is from the cancer. Research is currently being tested. Next step, experts will test on more patients, with different breeds of dogs. If successful, it will be an extremely cheap, highly effective, and non-harmful cancer test method.

Speaking of dogs' intelligence, it is impossible not to talk about it (Phu Quoc Ridgeback). This is the only native dog in Phu Quoc Island, Kien Giang and is classified as one of the rarest species in the world and very intelligent, easy to teach and loyal to the owner. Dogs are gray-brown, tapered belly, twisted hair on the back, yellow-gray fur with pale lines running along the body. Characteristics of only 3 species of dogs in the world are available, such as Thai whirlpool dog, South African lion dog and Phu Quoc dog of Vietnam. Up to now, only about 800 Phu Quoc dogs have been registered worldwide.

In October 2015, Catherine Lane, a 42-year-old British citizen became famous. Because she was the first European to own and successfully breed Phu Quoc dog. Lane to Vietnam, choose two black Phu Quoc dogs to bring home. After a hard time, the pair of dogs gave birth to 4 puppies: 3, 1 male, and they were ordered at £ 10,000 / child (about VND 300 million at the exchange rate at that time).

2. Dogs are walking with the toes and have characteristic feet, five toes on the front and four toes on the hind legs. Sometimes there are cases of domestic dogs that have five fingers on the front leg, hind legs, and the fifth nail called the "magic nail" or "dog of legend". The theme is said to be the remains of the big toe.

Humans often refer to special dogs: "Bisexual" is a dog with two myths, usually in the hind legs or the front legs; "Four nobles" are all dog legs must have a legend and be ranked "five-year general", so new people have the phrase "wise dog is perfect"; "Green Crane" is a child with two axes in each hind leg and a legend in each of the front legs, a total of six; "Crane" is each leg has two titles, a total of eight. This child is rated "Fourth General". According to humanity, the best types of myths are "Bat Long", followed by "Four Quarter", then "Luc Hop" and finally "Mesopotamia". " No matter who trades hundreds of jobs / Not equal to raising a four-legged dog." If you can keep this dog, the owner will get rich soon.

In the spiritual culture of some peoples, dogs are intimate animals attached to water with the owner in particular and people in general, the virtues of dogs are honored, so there are places where dogs are worshiped at the temples and shrines. Dog worship is quite popular in many peoples of the world.

Preparing for Tet holiday, I glided through shops selling feng shui, seeing many types of feng shui statues bearing different materials. In addition to traditional stone materials, feng shui dog statues are also made from high-grade stone powder to match modern trends and beautiful designs that bring a lot of vitality. There are dog statues made of quartz stone, very expensive.

What does feng shui dog mean in life? In the concept of Eastern people, dogs are animals that can bring good luck, convenience and lots of fun so they appear proverbs: "It is difficult for cats to come home. Dogs can come home . " This stems from the stories of the Ly Dynasty dog. Ly Cong Uan was born in Giap Tuat (974). In his hometown, there was a dog that gave birth to a white, yellow-speckled animal in the shape of "Vuong" on his back. That is the premonition of the year when Tuat gave birth to King and Ly Cong Uan to later become the Dragon .

In addition, the year Ly Cong Uan moved the capital from Hoa Lu to Thang Long, there was a pregnant belly dog ​​from Ba Tieu mountain, Bac Giang province, swam across Cai river, then up in Nung mountain (Botanical garden, Hanoi). If a dog is born, in the year of Nham Tuat, two dogs will be petrified, this place will be built after "Chinh dien dien" and set up a temple for the mother and puppy dog. Later dynasty, Cau Nhi temple was moved to the Imperial Citadel, built on a mound in Truc Bach lake.

People have created the proverb, based on the conclusions in the process of domestication, nurturing dogs and cats, and the legend of Cau Nhi in order to speak of prosperity for a new dynasty. Moreover, in the process of raising people, dogs were found to be very loyal to their owners, their homeowners were full and hungry. They did not leave them, protecting their owners to a great extent. "

In contrast to dogs and cats, when they eat, they stay, not eat and leave, ready to leave when they like - "fox old cat" is like that. It is the cat's abandonment, which shows the loss and the idea that cats come to bring bad luck and poverty.

But according to feng shui researchers: Gas fields affect humans and animals. When both humans and animals are alive, there is a biological ring, which is a combination of negative bioelectric particles surrounding the body. Biological waves and bioelectric currents spread in space. Humans and animals have the ability to transmit and receive biological waves. Biological waves can interact with each other or interfere. Thanks to the biological ring and bioelectric waves that transmit and receive, humans and animals get the so-called hunches and sympathies.

Dogs and cats are both good animals, especially dogs that know in advance what bad things happen to their owners. In many cases, when the owner went out, the dog spirit felt that the bad thing bitten the pants and kept the owner, or saved the owner from danger. Moreover, dogs still feel strange sources of waves, bad waves to scare away, warn them, so the humanity has the phrase "to be as anxious as a dog". Between humans and dogs there is also a conflict between two sources of biological waves, so there are people who go through dogs without biting, but some dogs bite very hard.

On the contrary, the cat's premonition ability is to report bad news like, see dead people as cats come and wake up dead people . The phenomenon is also called "entering the devil". According to biologists, feng shui learn: Black cats are very strong animals. The dead are lacking in positive qi. When the cat gets close to the corpse, the cat's strong positive gas can cause the dead body to be nervous, thus the reaction will occur. It is these things that make people think differently about good and evil in dogs and cats. As for science, there have been certifications about earth school, radiation node . Through observation, people have noticed that cats like the areas with radiation or bad gas fields. In contrast, dogs prefer areas with radiation, good gas fields. Therefore, the places where cats lie often have bad air, dogs or lying down. Therefore, dogs or cats come to the house, which is due to the charm of some gas and radiation fields that have just arisen in their area.

3. All the factors of luck and risk are the summation and experience of grandparents, ancestors, lineages, generations of retransmission history, with a practical basis. Not to deny these conclusive experiences, but relying on it to look for luck, or worrying about some vague risks that occur away from reality is wrong. Both dogs and cats are, are good friends of humans. But animals are still animals: The dog's brain has 530 million neurons, cats only have about 250 million, humans have about 16 billion neurons. For people, only true labor creates wealth and every opportunity arises, ie fortunes for oneself.

Science is still finding ways to explain the dog's intelligence, there are compelling explanations, there are things that are not very clear, so the study of dogs still continues. Maybe the next year of the Dog will have new things.
