Do you know why your pet dog or street dog starts barking as soon as they see certain people? While other people pass by comfortably, it does not matter to them. If you are also troubled by this question, then today we will know its interesting and scientific reasons.

Often, we feel that dogs bark only at strangers, but the truth is that this is not the whole story behind it. Dogs have a special power of smelling and hearing. Yes, they understand a lot from the smell of humans and their way of walking. Let's find out.
Sense of keeping the territory safe
Dogs have a deep sense of keeping their territory safe. When a stranger comes to their territory, they bark to warn him. They feel that it is a threat to their home or family. If a stranger comes to them suddenly or fast, they consider it an even bigger threat and bark more.
Fear and insecurity
Some dogs also bark due to fear. If a dog is not socially trained, it gets scared of strangers. Due to that fear, it starts barking so that strangers stay away from it. Many times, people inadvertently scare dogs, such as by suddenly approaching them or staring at them. In such a situation, the dog can bark out of fear.
Body language and smell
Dogs understand not only by voice but also by body language. If a person is scared, dogs sense it immediately. They sense the fear of that person from his smell and gestures. In such a situation, dogs feel powerful and can bark at him.
Apart from this, dogs can also feel uncomfortable with the gait or clothes of some people, due to which they start barking.

Reason for old experiences
Dogs always remember their old experiences. If a person has ever hit or frightened a dog, then that dog is wary of all people like that. This is why sometimes dogs react immediately on seeing some people because they feel that this person can also be a threat to them.
