Why do dogs bark where no one is around?

Because dogs have a stronger sense of smell and hearing than humans. Many dog owners have encountered this situation to a greater or lesser extent: either walking their dog on a sunny afternoon, walking on a dark and gloomy road, or even in their own home, the dog suddenly yells at the "quiet" place ahead for no reason.

Some old notions believe that dogs can see "dirty" things that humans can't, and in extreme cases even invite old wizards to compete. Today, from a scientific point of view, why do dogs bark in a place where no one is there for no reason?

In order to understand this question, first we need to know why dogs bark. Dogs are particularly alert, and the likelihood of barking can be broadly categorized into excitement, warning, fear, defensive warning, and frustration. In particular, some puppies of short stature, similar to Chihuahuas, are particularly sensitive, easily scared, and will be considered dogs that love to bark.

Dogs have a particularly keen sense of hearing, and their hearing range is 400 times that of humans. Ears can distinguish between very small and high-frequency sounds, and they also have a strong ability to judge the source of sound. When you hear a dog barking in a place where no one is around, it doesn't mean there isn't a whistling sound.

It could be a funny or frightening sound in the distance that you can't see.

A dog's nose contains more than 200 million olfactory cells and can easily distinguish odors in different concentrations emitted by about 200 substances。In addition, dogs have a strong sense of territory. As soon as there is any peculiar smell in the area, it is keenly perceived.

Therefore, it is also possible that there is a particular smell that the dog does not like, which makes the dog bark for no reason.

Therefore, having a scientific and reasonable understanding of dog behavior is a necessary quality requirement for a good shovel.

Sometimes the dog will suddenly stare tightly at a certain place in the house where no one is and bark loudly, and we go to look for nothing! Why do dogs bark at places where no one is around?

Why do dogs bark at places where no one is there for no reason? The reason is so heartwarming.

The world of dogs is different from the world of humans. What you see as "nothing" actually contains a lot of information for dogs.

The human ear can hear sounds at frequencies between 20Hz and 20kHz, while dogs can hear higher frequencies. If you notice a dog lying on the ground suddenly standing up and watching alertly, it may be that it hears a high-frequency sound and feels danger approaching. And you can't hear that high frequency, so you think he's observing "nothingness".

There are many other conditions, such as the dog's sense of smell is far more developed than that of humans, it can smell the scent of strangers and respond, the dog's eyes can adapt to the night environment, and the night vision ability is far beyond that of humans. The pads on the feet of some cats can feel the ground vibrate, so they can sense the movement of large animals at a distance. So the dog doesn't bark "at nothing".

3. It is said that Chinese folklore says that the eyes of dogs can see things that humans cannot see. Sometimes he barks at people suddenly. It could be because the dog suddenly saw something in a human. And the legendary Black Dog.
