Although the dog can not think like a human, it has a highly developed nervous system and sensitive sense organs; some intelligent dogs will even be aware of the owner; you smile at it and behave very well.

Observe your partner, and you will find out how good the dog is at expressing itself.

1. How long does a dog live?

The average lifespan of a dog is about 13 years, which means that if it lives to be ten years old, it should live out its life in peace, and its highest longevity record is 34 years.

The lifespan of a dog is affected by the nutritional status, living environment, and other conditions, and dogs kept indoors live longer because of their excellent living conditions. The dog’s life expectancy is related to the breed’s coat color, etc.

The mongrel has a longer life expectancy than the purebred, whereas the black dog, in turn, has a longer life expectancy than the other coat colors.

The life expectancy of the dog and the size of the body also have a special relationship.

Generally speaking, the smaller the body size, the longer the life span because, physiologically speaking, the metabolism of large dogs is faster than that of small dogs, and the heart and lung burden is relatively more significant.

2. How sensitive is a dog’s sense of smell?

The dog’s sense of smell is known to be sensitive to odor and the ability to identify the scent. Dogs have the highest olfactory sensitivity among all animals because their olfactory nerves are densely distributed on the nasal mucosa, occupying four times the area of humans. Their sensitivity to odor is more than 40 times higher than humans.

According to the measurement, there are only 5 million olfactory cells in humans. Still, dogs have 220 million and can distinguish more than 20,000 different odors, and police dogs can even distinguish more than 100,000 other odors.

Because of its keen sense of smell, it can identify the sex of the same kind, the state of heat, parent-child identification, and identify the road, location, food, and prey.

People use the dog’s acute sense of smell to train military dogs, police dogs, drug detection dogs, hunting dogs, herding dogs, and so on, and even participate in search and rescue work, doing a lot of work that humans cannot do.

Dogs often use their sense of smell to identify their owners, determine the gender of their kind and food, etc. It will know what has happened here based on the scent left on the ground or in the corner.

Two dogs met, through the smell of the butt, quickly know each other have a good time, how the mood. It is even susceptible to the body odor produced by human anger, fear, hatred, and happiness.

In short, the dog’s work and life entirely depend on the nose with a keen sense of smell; to maintain a sharp sense of smell, it will lick its nose wet from time to time, only when sick.

When a dog is sick, its nose looks dry. When the dog is sick, the nose seems dry. It is also dry when it just wakes up because it hasn’t had time to lick.

3. The beginning of the dog, the nature of evil?

A dog’s nature is to defend its home – including its own and its master’s territory, and if it perceives danger to its beloved master, it is obliged to act.

No dog is born vicious and cruel, and some dogs used to guard, and the guard is fierce, but that is the result of people’s training, and it is people who teach them to attack and hurt.

The dog cannot judge, and its loyalty sometimes becomes a tool to manipulate it to hurt others, which is unfortunate.

Some dogs become very wary of people because humans have cruelly abused them, and that is because they become vicious out of fear. Nevertheless, dogs are animals that live in reality, and most of them will quickly put aside the memories of abuse and prefer love.

4. What does a dog’s bark say?

Although a dog cannot speak, it can perfectly express emotions and desires through different barks, including grunts, squeals, wails, growls, and low barks.

A light woof from a dog tells everyone it’s having a good day; a soft whine may indicate hunger and a desire to eat; a sharp nasal chirp indicates impatience, and a low cry is a warning to strangers to stay away, and if the dog shows its teeth while making this sound, then you need to find a way to escape.

When you put the volume of the TV or stereo to a high level, the dog may make a painful howling sound because it is sensitive to sharp sounds, then turn down the volume a bit, and it will be fine. In addition, the dog will make a low whimpering sound when it is happy, which may be singing to its owner; you should not think it is growling.

The ancestors of dogs, wolves, howled to call back their lost companions, and of course, they howl when they are lonely or happy. So when a dog has locked up alone, it may bark because it is lonely and boring; you can not care; this is its primitive instinct.

5. Do dogs have super senses?

Dogs can know in advance of earthquakes and volcanic eruptions. Some dogs can be thousands of miles away, years apart, and still find their way home. That’s the power of prophecy!

A well-trained dog can understand its owner’s meaning from its eyes without even waiting for the owner’s command because of a mysterious supersensory ability between humans and dogs.

The dog can also detect human potential health problems through the supersense, or an “aura.” For example, it can know in advance that a person’s epilepsy is about to seize; because epilepsy has a particular vibration wave before the seizure, the dog can be sensitive to detect in the human “aura.”

Interestingly, dogs can also “see” a person’s true nature through the “aura.” Although a person can hide his essence through vague words and flashy appearance, it is difficult to hide it from the dog’s eyes. Chinese folklore says that if a person does not like the dog, then this person is not to make friends.

6. How to read the dog’s body language?

The dog lives in the world as a life, it has pain and joy, just like us, but it is not as good at hiding its emotions as humans.

Its happiness, anger, sadness, and joy can not be distinguished from the face alone, but we can combine the movements of its body parts to observe out; mastering the dog’s body language is also of great significance for training.

The performance when happy: wagging the tail and jumping around the owner is a familiar scene. At this time, pay attention to its face; you can see the nose is full of wrinkles, eyes slightly closed, soft gaze, two ears together, mouth slightly grinning, but also issued a sweet nasal sound.

When angry: The dog’s facial expression when mad is almost the same as happy, with lips grinning and teeth showing. The difference is that the eyes are wide open, sharp, the facial expression is tense, the ears are crossed, a threatening low sound is emitted from the nose, the four feet are stomped hard, the body and tail are stiff, and the hair is erect, making it look more intimidating.

Next, if its two front legs crouch down and its body sits back, you’ll have to find a way back quickly because it’s about to attack you.

Fear: tail between the two hind legs, ears to the back, hair erect, eyes wide open, trembling, crouching neck to hide in the corner of the house or behind the owner.

Performance when mourning: lying down in the corner with head hanging, becoming extremely quiet, or looking at the owner with begging eyes.

Restlessness: neck stretched forward, erratic barking from the nose, tail drooping, front paws pawing at the ground, or rubbing the owner’s thigh with the body as if asking for help.

The dog’s head is lowered and stretched towards the owner; the gaze avoids the owner, the ears droop down, the torso lowers, almost lying on the ground, then expresses subservience and reverence to the owner.

7. What are dogs afraid of?

Dogs are naturally timid, and the lightning and thunder when it rains can scare them so much that they shiver and go under the table with their tails between their legs. This time, no matter how comforting the owner, it can not stabilize its emotions, is nursing mother dogs may also be scared to nervousness and eat their pups.

Dogs also fear fire, but its performance is not to run away but carefully around the fire barking. We can use this feature of the dog to report the fire alarm.

Dogs also have a strong sense of fear of death; the smell of the same kind of death is a strong stimulus to the living dog. Some dogs also have a fear of shoes made of leather, probably because of the smell of other animals left on them.

Dogs also have a fear of phenomena they cannot understand, such as a lifeless animal specimen, an electric toy that makes a sound, a leaf blown by the wind, an umbrella that suddenly opens, and so on.

8. How does a dog sleep?

Dogs need about 15 hours of sleep a day, but it is not like people sleep until dawn; it is a chance to sleep lightly for a while, head on the two front legs, ears to the ground, the slightest movement will be awakened.

When it lies on its side in the sun at noon, the whole body stretches, and sometimes the lips twitch to send out a dream, which is considered to be asleep, but if there is a stranger’s voice, it will still wake up.

Dogs in sleep always like to hide their mouth under the two hind legs because it wants to protect their precious nose. If it does not get enough sleep, the dog’s working ability also decreases. It likes to lie down, always yawns, and its mood becomes terrible.

9. Do dogs use urine to determine their sphere of influence?

Dogs have a strong sense of territory, which is demonstrated by their having to leave urine traces as a sign in every place they visit. It can be very active in its environment.

Still, when it comes to other dogs’ territory, it becomes cautious, which is why dogs are nervous and shaking when they arrive at the entrance of the animal hospital.

The dog is intensely aggressive; it will often update the urine trail used to expand the territory. When a male dog goes out for a walk, he always leaves a little urine under a tree or in a corner.

A small dog will try to lift its hind legs to urinate when it passes by the urine trail left by a dog more significant than it, trying to cover the traces of the big dog.

In contrast, the big dog passes by the urine trail of the small dog, but to urinate in as low a position as possible, the purpose is also to cover the traces of the small dog.

The female dog’s sense of territoriality is less intense, leaving traces of urine everywhere when she is in heat to tell the male dog how she is feeling. A male dog who encounters a more aggressive dog to occupy the land will have to pin the tailback to the old den.

10. why does the dog bury the bones?

This is an old tradition of the wolf, its ancestor because wolves live by hunting, but there are not many chances to catch prey, and sometimes they have to go hungry for several days in a row.

So once they have a harvest, they rub a meal furiously, and when they really can’t eat anymore, they use their front paws to dig a hole, arch the soil with their mouths and bury the remaining delicacies.

Dogs living in today’s human families are well fed and clothed, but digging and burying food has become a deep-rooted memory in their minds.

After hiding their delicacies, most dogs don’t bother with them anymore and leave them to rot or be enjoyed by other dogs. Some dogs also like to collect toys for the same reason.
