What's the difference between a wolf and a dog?

As far as temperament is concerned, the biggest difference between wolves and dogs is that "wolves have always been wolves, and dogs sometimes become people"! Wolves have their own image, baiwenhang, ambitious and in cahoots. Dogs are described as pugs, lackeys, dog minions and dog legs. As the saying goes, "follow the wolf to eat meat, follow the dog to eat shit." The difference between the two is actually clear at a glance! People are afraid of wolves, so people hate them. Dogs are afraid of people, so people love dogs. The right and wrong of wolves and dogs lies in human judgment, not in wolves and dogs themselves. The wolf's nature is to eat meat, including human flesh, and nothing else. Dogs, like people, eat meat, vegetarian food and even shit when necessary. For example, flattery is worse, and flattery is biting your teeth, which can be understood as eating shit. Wolves disdain this kind of thing, which is in our nature, and dogs can sometimes eat shit for others, which can reduce people's burden to some extent. People naturally appreciate dogs! Dogs are dependent and can be domesticated as human slaves, that is, people can train dogs to be close to people. As long as the IQ of animals is close to that of people, they can have a more tacit communication effect with people, such as body language such as bowing, shaking their heads and wagging their tails, which will bring unprecedented pleasure to their owners. Wolves are independent and self-reliant. It will not be domesticated artificially, and even sometimes it will form an antagonistic relationship with people. This character is very dangerous for wolves. Think about it; What is a person? Man is an animal whose eyes can't hold half a grain of sand. If he wants to fight human beings, the fate of the wolf can be imagined how tragic! Wolves and dogs actually show two sides of human nature. Some people are wolves, others are dogs, so don't regard the attribution of human nature as the image of a dog, and don't think you are a wolf. Being with wolves is called dancing with wolves. Being with a person like a dog is called "take all". There are many people dancing with wolves in the circle where we live, and there are also many greedy people. As for how to choose your own lifestyle, it's entirely up to you. Of course, it depends on the nature. The wolf's ambition is nature, and so are the dog's legs. Human nature is also the inheritance of nature. This nature is beyond human control. What genes your ancestors left behind, you are a creature. If you try to change forcibly or deliberately, you are a hypocritical, hypocritical dog in wolf skin! Wolves can't become dogs, and dogs can't become wolves, which is something they can't choose. But people can be wolves and dogs, and dogs and wolves can be exchanged. This is human freedom. However, this freedom of human beings also has certain limitations, and we must make necessary choices based on survival. Some people can live a wolf's life freely, while others have to live a dog's life like eating human excrement. People are very lucky! I don't worship wolves, and I don't like dogs, let alone that I am a wolf, but I have the right to choose to stay away from dogs! It is the most reasonable fact that both wolves and dogs exist objectively. But wolves and dogs must never live together, otherwise they will either make the dog angry or suffocate the wolf. In short, this result is not good for anyone. As the saying goes, carrots and celery have their own tastes, and the road goes higher. You go your way, I'll cross my wooden bridge! They're all gone anyway, and the result is another matter. The key is to be comfortable! In terms of biology, wolves are characterized by small (coyote), medium (coyote) and large (coyote), with a long snout and slightly prominent eyes. Because of different origins and genes, the coat color is also different. Common grayish yellow, black, red, white and other colors, as well as purple, blue and other colors, the chest and abdomen are shallow. Legs are slender and powerful, and they are good at running. The weight and size of gray wolves vary from region to region, and generally tend to increase with the increase of latitude. Generally speaking, the weight of wolves with shoulder height (26-36 inches) and weight of 32-62 kilograms (70- 135 pounds) is recorded, among which 1939 is in Alaska. It was 80kg( 175 lbs). The youngest wolf is arabian wolf, and some females weigh as low as 65,438+00 kilograms (22 pounds). Wolves are suitable for long-distance migration and hunting. Their powerful backs and legs can stretch and run effectively. The wolf's mouth is long and narrow, with 42 teeth. Wolves have five kinds of teeth, incisors, canines, premolars, cleft teeth and molars. There are four canine teeth, two on the top and two on the bottom, and the length can reach 1.5 inch (2.8 cm), which is enough to pierce the skin of prey and cause great damage. There are also four cracked teeth, which are differentiated from molars and are also the characteristics of eating meat. Cracked teeth are used to cut meat. 12 The upper and lower six front teeth are relatively small and are used for biting. Living habits of wolves Wolves are highly gregarious species. The number of wolves in a pack is about 5 to 12, and it can reach about 40 at most in cold winter. Usually a family of wolves is led by a dominant pair, while a group of brothers and sisters are led by the strongest wolf. Wolves have territory, usually their range of activities. If the number of individuals in the group increases, the territory will shrink. The domain ranges between groups do not overlap, and the ranges will be announced to other groups through howling. Young wolves will stay in the group to take care of their brothers and sisters when they grow up, or they may inherit the dominant position in the group, and some will migrate out (mostly male wolves). In some cases, there will be migrating wolves, with hundreds of wolves in a group and various family levels. The original wolf head of each small group will become the first wolf, and the best wolf will become the wolf king. Generally, wild wolves can live for 12- 16 years, and some artificially raised wolves can live for about 20 years. The running speed is extremely fast, up to about 55 kilometers, and the durability is also very good. They have the ability to run at a speed of 10 km/h (six miles) for a long time, and can chase and sprint at a speed close to 65 km/h (40 miles). If it is a long-distance race, it will be faster than a cheetah. High intelligence, can communicate by smell and cry. Wolf is a carnivorous omnivore and a key link in the biological chain. Dog habits 1 Dogs are carnivores. When feeding, animal protein and fat should be prepared in the feed, supplemented by vegetarian ingredients to ensure the normal development and health of dogs. Dog's digestive tract is shorter than that of herbivores, and the content of hydrochloric acid in dog's stomach ranks first among domestic animals, and the absorption capacity of intestinal wall thickness is strong, so it is easy to digest meat food and suitable for digestion. 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. The dog's defecation center is not developed enough to defecate while exercising, so give it a certain defecation time. Dogs like to bite. This is also the habit of biting prey in the original ecology. When feeding, give it some dog bones from time to time (dogs can't feed it poultry bones, it is best not to feed pigs and cows) to facilitate grinding their teeth. Dogs have unique self-defense ability. After eating toxic food, they will cause vomiting reaction and spit out toxic food. In hot summer, the dog's mouth is wide open and its tongue is 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. When a dog is lying down, he always turns around to see if there is any danger around him, and then he will sleep peacefully after making sure there is no danger. 10 Dogs like to be caressed on their necks and backs. 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. 1 1 The dog's code of conduct for strangers is to judge the strength of the opponent according to the height of the line of 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. 12 dog society has certain rules. They will never attack opponents who fall down 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. By the way, the only cruel animals that can violate the same kind of agreement are humans and birds. 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. 13 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. 14 in terms of memory, 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. 15 When dogs are sick, they 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. As soon as 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. 16 The movement of the dog's 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 from side to side, 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, give me a kiss. " The dog refused, so he obeyed. If you observe dogs for a long time, you will find that dogs sometimes eat grass. So why do dogs sometimes eat grass? The gastrointestinal structure of dogs is different from that of people, which is an important reason why dogs eat grass. The dog's stomach is very big, accounting for about 2/3 of the abdominal cavity, but its intestines are very short, accounting for about13 of the abdominal cavity. Therefore, dogs basically use their stomachs to digest food and absorb nutrients, which is easy to digest meat food, but not easy to digest things with "tendons" like leaves and grass. Dogs sometimes eat grass, but eat little and occasionally vomit. Dogs eat grass not to satisfy their hunger like cows and horses, but to clear their stomachs. When a dog feels indigestion and has a fever, eat some grass, which turns into feces and expels other things in his stomach. Summary: Dogs are animals that often appear in human daily life. Dogs are actually the descendants of domesticated wolves.
