Watch the door and make a zodiac sign. Explain why?

Dogs belong to the animal kingdom-vertebrates-mammals-Carnivora-Canidae-Canidae. Dog is one of the 12 zodiac animals. The affection between dogs and people can be traced back to thousands of years ago. People have reason to believe that the affection between dogs and people will continue in the future.

No animal serves us in so many ways as dogs: dogs do their duty to graze for us; Dragging us through the coldest and most remote corners of the earth. With a sense of smell that is 1000 times more sensitive than ours, dogs can search for people buried under snowdrifts after avalanches, rescue people trapped in rubble after houses collapse, and lead the way for people lost in the depths of forests. They stand guard at the border to stop drugs and other illegal transactions. They guide the blind and tirelessly take care of the lives of the disabled. Dogs are our partners, friends and allies. They always know our needs, listen to our orders and warm our hearts with endless care.

We know that dogs were domesticated by wolves more than ten thousand years ago. Although people have developed various theories, we are still not sure why humans and dogs can get along so well. Need to protect each other, hunting together or friendship? Or all three? People who love dogs may prefer the saying that God created people, and seeing that human beings are so pitiful, he created dogs for us.

Dog habits

[Edit this paragraph]

Dogs are carnivores. Animal protein and fat should be prepared when feeding, supplemented by vegetarian ingredients to ensure the normal development and health of dogs.

② The digestive tract of dogs is shorter than that of herbivores, and the content of hydrochloric acid in dogs' stomachs ranks first among domestic animals. In addition, the intestinal wall thickness has strong absorption capacity and is easy to digest, which is suitable for digesting meat food.

Dogs belong to the wolf clan, and they don't chew very much, which can be described as "wolfing down". If you want to feed coarse fiber vegetables, you'd better chop them up or cook them.

④ The dog's defecation center is not developed enough to defecate on the move, so we should give it a certain defecation time.

Dogs like to bite. This is also the habit of biting prey in the original ecology. Give it some bones from time to time when you feed it, which is good for grinding your teeth.

Dogs have unique self-defense ability. After eating toxic food, they will cause vomiting reaction and spit out toxic food.

⑦ In hot summer, the dog's mouth is wide open and its tongue is very long, and it relies on the evaporation of water in saliva to dissipate heat.

When dogs live in groups, there is also a "hierarchy" and a master-slave relationship. Establishing such an order can maintain the stability of the group and reduce the struggle caused by the struggle for food and living space.

Pet-name ruby when lying down, the dog will always turn around, perhaps to lie down comfortably, perhaps because of some instinct left over.

Attending the dog's neck and back like being caressed. Try not to touch the top of your head, because it will make it feel depressed and dizzy. Besides, you can't touch your ass or tail. "Dogs can't change but eat shit" is the biggest vice of dogs and must be corrected. Dogs not only eat human shit, but also eat shit.

The dog's code of conduct for strangers is to judge the strength of his opponent according to the height of his sight. When a stranger approaches, the oppressive feeling of coming down from above will make him uneasy. If you keep a low profile, he will accept you. If it is lower than the height seen by its eyes, it will make it feel more secure. The dog's weakness is on the right, and it will make actions to protect the right. When it is cornered, it will lean its right side against the wall and its left side will face the enemy. This habit is a dog's innate instinct. The dog shows its belly to others as a sign of obedience and surrender.

Dog society also has certain rules, and it will never attack opponents who fall and show their bellies. When a dog sleeps with its stomach down, it shows that it is very relieved or trusting, so that people can see or touch its stomach. Dogs like people more than their peers, not only because people can take care of them and give them food and shelter. The main reason is that dogs keep company with people and build feelings. Dogs have a strong sense of protection for their owners. Some dogs rescue children from water, burning houses or under cars. A dog will help its dog friend who is in pain or injured.

Dogs have territorial habits, that is, they occupy a certain range and protect them from other animals. They use anal gland secretion to make feces have a special smell, sweat secreted by sweat glands between toes and pictures of scratching on the ground with hind legs as territorial markers. Dogs are very jealous. When you notice the new dog and neglect to take care of it, it will get angry, disobey its habit and become irritable and destructive. Dogs also have vanity and like to be praised. When it does a good thing, or does some tricks, you clap your hands to praise it and touch it, and it will be as satisfied as a full meal. Dogs are also shy. If they do something wrong, or if their hair is cut too short, they will hide somewhere and wait for hunger.

As far as memory is concerned, dogs never seem to forget the voices of people they have been close to, and they can also remember the places where they have lived. However, some people think that dogs rely on sensory sensitivity to recognize the voices of acquaintances and know the location. Dogs like to smell anything. Smell territorial marks, new dogs, food, poison, feces, urine and so on. When the dog is wandering outside, we often see it constantly urinating or squatting down and scattering feces on the road. And it walks by these "smelly marks". Dogs like to chase animals. Like hunting small animals. Chase rabbits, cats, sheep, etc. Even chasing humans, people use this characteristic of dogs to drive away cattle and sheep and protect themselves.

When a dog is sick, it will instinctively avoid humans or other dogs and hide in the dark to recuperate or die. This is an "atavism". The ancestors of dogs lived in groups. If any dog in the group is sick or injured, other dogs will kill it to avoid all the trouble or pain after falling behind. This should attract the attention of dog owners or breeders and should be treated by veterinarians in time. Dogs like alcohol the least. When giving injections to dogs in the veterinary hospital, behave yourself first, and then rub alcohol. Once the dog smells alcohol, its hair immediately stands up and growls. Dogs are afraid of fire, so they don't like anything that smokes, such as lighting matches and smoking. Dog tail, the movement of dog tail is also a kind of "language".

Although different types of dogs have different tail shapes and sizes, their tail movements express similar meanings. Generally, when the host is excited or happy, he will shake his head and tail. The tail not only swings to the left, but also keeps spinning. The tail is tilted up to show joy; A drooping tail means danger; The tail does not move, indicating anxiety: the tail is tilted, indicating fear; Shake your tail quickly and horizontally, symbolizing friendliness. The movement of the dog's tail is also related to the owner's tone. If the host says to it in a friendly way, "Bad guy! Bad guy! " It will also wag its tail to express its happiness; On the other hand, if the owner says in a stern tone, "Good dog! Good dog! " It will still pick up its tail and show unhappiness. That is to say, for dogs, human voice is just a sound source, an acoustic signal, not a language. The human smile and the wagging of the dog's tail are similar forms of communication, but I didn't realize that dogs only wag their tails at living objects until I read "Dog Intelligence" by Stanley Curran. Dr. Curran said that a dog lying there alone won't wag its tail, even if it has its favorite inanimate object in front of it. A dog may like to eat certain foods, but it won't wag its tail at them unless other creatures are present. Jean craighead george has the same view in his book How to Talk to Your Animals: "Dogs wag their tails only for living things, but wagging their tails is equivalent to human smiles, only for people, dogs, cats, squirrels, even mice and butterflies, and not for inanimate objects. Dogs don't wag their tails when eating or sleeping, cars, sticks or even bones. " However, this statement is still controversial. Bi Foucault, a scholar who has a good knowledge of canines, told me that this is actually wrong: he once saw a dog wagging its tail while eating in another room. Is it because the dog found someone watching it? Unlikely. My veterinary friend Federman in Berkeley agrees with Bikov. In any case, a dog's tail can convey a lot of information. Even if dogs wag their tails regardless of living or inanimate things, this still cannot change the fact that dogs like close emotional contact, which is the main reason why they wag their tails when they see us. No one will misunderstand their meaning. Just watch the dog wagging its tail at a stranger, and you will know that many, if not most, people will immediately have a warm and even embarrassing conversation with the dog: "You cute, sweet and beautiful little guy, look how smart and wonderful you are!" Come on, give me a kiss. The dog refused, so he obeyed.
