Sense of smell Dogs are ruthless animals and at times do not recognize people.

Through smell, the dog's sense of smell is very sensitive, and it also has vision.

The dog's nose has a strong sense of smell and observation, and in addition to smelling, it can also read the owner's expression.

Dogs rely on their sight to recognize people.

1.Motor memory: In the training of dogs, there are many items related to motor memory, such as the obstacle jumping events completed by dogs or lying and sitting. This kind of memory training is very important.

2.Image memory: These images can be auditory, visual, olfactory, tactile, and tasteful, such as the dog's memory of the owner's appearance characteristics, which is visual.

Smell, feeling. In short, you can recognize the owner's words.

After getting acquainted with your dog, your dog will remember what you smelled like, so when you spray other scented perfumes on your body, it won't recognize you.

1. Through vision.

Like humans, dogs also see everything through their eyes and reflect it in their minds, dogs' eyesight is much better than that of people, it can see everything that happens in the distance, so dogs can remember their owners through their eyes and see their owners happily at any time.

2. Through the sense of smell.

In fact, the sense of smell is the most commonly used and most sensitive sense of dogs, the dog's sense of smell is very sensitive and memorable, they can remember a lot of smells, especially the owner's smell, no matter how long it takes, they will not forget. So dogs can easily tell if there is a scent of their owner among people nearby, even if it takes a long time.

3. Through hearing.

Everyone's voice is different, each has its own characteristics, and the dog is the most sensitive to the owner's voice, just like in the crowd, the dog that hears the owner's call will quickly run to the owner's side, if it is a stranger calling the dog's name, the dog is to look in the direction of the sound, and find that it is not a person who does not know it.

Among these three senses, the dog relies most on hearing, the appearance will change, the smell will change, but the sound is the least change. Therefore, many dogs see their owners after a long time, in fact, their first reaction is to bark and treat the owner as a stranger, but as long as the owner calls the dog's name or makes a sound, the dog can always recognize the owner at the first time.

The dog is a very sensitive animal, the dog's nose has a lot of wrinkles, these folds are covered with olfactory cells, 40 times higher than humans, the dog keeps a moist nose, so that this sense of smell is kept more sensitive, it can smell a lot of different smells, and to distinguish the taste from **? Whether it was from the owner or from another stranger?

Dogs also have a very sensitive sense of hearing, they can hear sounds that we humans can't hear, with high frequencies of up to 1 million hertz, and can also distinguish the small difference between more than 90 vibrations per minute and 100 times per minute. Therefore, the dog can distinguish the voice of each different person, from the tone of their speech, the sound of their walking steps, effectively distinguish different people, is it the male owner or the host? Or a little princess?

The dog's vision is also very powerful, although it sees a little less color than a human. However, dogs' dynamic vision is much better than that of humans, and they can distinguish the footsteps of people or animals moving from hundreds of meters to 1 kilometer.

Therefore, the dog distinguishes whether it is the owner or a stranger, through the sense of smell, hearing, vision, etc., after analysis and comprehensive judgment of the brain, whether it is the owner or a stranger.

The dog is a loyal friend of human beings, as long as you are good to it, it will never forget you, remember at that time, go to a friend's house to play, its dog is very cute, very well-behaved, at that time specially bought ham sausage for it to eat, it was happy, desperately wagging its tail to please the owner. After a long time I didn't go, about half a year to go, the dog saw me, very excited and happy, jumping and jumping, shaking his head and tail, and pounced on me, all the clothes were dog paw prints, and he was helpless.

A dog's nose is so smart that his sense of smell can tell if it's his owner. This is also the reason why there will be police dogs to help solve crimes.

Recognize the owner from sight, smell, and hearing, especially the sense of smell, the sense of smell is the most commonly used and most sensitive sense of dogs, the dog's sense of smell is very sensitive and memorable, they can remember a lot of smells, especially the owner's smell, no matter how long it takes, they will not forget.

My dog doesn't recognize by smell at all, he also looks and dresses, and sometimes he will recognize the wrong person or the wrong door.

The dog's sense of smell is very sensitive, it can smell the smell of the owner, and naturally knows the owner.

By hearing, I was sure that my dog had not seen me for a long time, and when he saw it, he barked at me, and then I called its name, and he was stunned for a moment, and at once recognized me, and pounced on me happily and quickly.

Untrained dogs are not very good at distinguishing people by smell, they all see with their eyes, and then they use their ears to distinguish.

Through the smell, the smell of each person's body is different, and the dog's nose is more sensitive, so it can easily smell the owner's smell.

Why do many dogs not recognize their owners, such as huskies, Alaska... I've been raising it for almost 2 years, and I didn't go out of the house.

Smell, I heard my mom say I only spent a few months at my grandmother's house when I was born, and then I went home, and when I was five or six years old, I went to my grandmother's house, and their dog still remembered me.

I feel like it's by smell. But sometimes when I see the owner from a long distance and run over, it shows that the vision is also useful.

I call out to my dog on camera, and it rushes to the camera and howls like a wolf in response.

I think dogs can distinguish human faces, and I have a windowsill on the second floor for dogs to go up to look at the wind, and when I see family acquaintances from afar, I hum and then run to the door and wait, if I want to say that the nose smells unreliable, it's far away
