Since the beginning of hunting in ancient times, dogs have been getting along with humans. The dog's vigilance is extraordinary. Its nose can even smell the breath 3 miles away. It also has a pair of sensitive ears... Dogs have been with us for a long time. , but how much do you know about it? Let’s take a look at the treasures and secrets of dogs.
Sensitive sense of smell
Dogs are naturally nocturnal, and the acuity of the sense of smell is more powerful than the acuity of vision. Compared to wolves, foxes, and elephants, it is even worse. Therefore, we often see police officers working with police dogs to detect cases. Dogs search precisely by tracking the same scent.
360-degree field of view
Although a dog's vision is not as powerful as its sense of smell, its visual width can be almost 360 degrees. Normally, people cannot see things behind them, but dogs can, and their field of vision is very wide.
Keen hearing
A dog's hearing can be said to be a sound identification machine. No matter how small the sound is, it can determine the source of the sound within a few seconds, even if it is ultrasonic . Even if it falls asleep at night, its ears still maintain a high level of sentry status, and it can make good judgments on sounds within a radius of 2 miles at all times.
Attitude of the tail
A dog's tail represents its attitude. When it sees an acquaintance, it will wag its tail left and right, and it will rotate its tail when it is happy; if it is wagging its tail horizontally, it means friendly and welcoming; when it meets an acquaintance, it will wag its tail. When feeling danger or uneasiness, the tail hangs down and does not move; the tail is clamped between the thighs to express extreme fear.
The little secrets of dogs
1. The life span of dogs is generally about 10-20 years. Generally, smaller dogs have longer life spans.
2. When a dog is sick, it will instinctively avoid people and hide in a quiet place with few people, waiting to recover or get worse. It is commonly known as " atavistic ".
3. Dogs will never forget the smell of people who have been close to them, even if a long time has passed.
4. We should not yell loudly at dogs. Loud decibel sounds can cause psychological stimulation to dogs. Like humans, they are easily traumatized by frequent stimulation, making them fearful, painful, and even avoidable.
5. We often see that a dog’s nose is wet. This is not due to the gas it exhales, but because the dog is afraid of heat, but does not sweat, and the nose is its perspiration channel.
