The vicious dog threw himself on the street and bit the boy for 3 seconds. Why did the dog attack the boy?

In recent years, there have been frequent incidents of injuries caused by vicious dogs, and the use of rabies vaccine in China alone accounts for 8% of the world. Not long ago, another boy was bitten by a dog near the auto parts city of Hongda Road, Lianxi District, Jiujiang, Jiangxi. A vehicle driving recorder filmed the whole process. According to the video, the dog suddenly jumped on the boy and bit him. Fortunately, many passers-by came and drove the dog away with a broom and stick, and finally regarded the dog as a boy. The accident caused the boy's thigh injury, and the dog bit two holes the size of coins, which was shocking. The reason why the dog attacked the boy is still unclear. It is speculated that there may be the following reasons:

First, the dog was frightened or provoked. Generally speaking, dogs don't take the initiative to attack people, except for mad dogs. Most dogs should take the initiative to avoid humans, and they will not take the initiative to attack unless they have to. If the dog is frightened, it may have a stress reaction and attack people around it. Or the dog is constantly provoked, such as throwing stones at the dog, or constantly teasing, which may irritate the dog and lead to aggressive behavior.

Second, children are smaller. Dogs actually pick soft persimmons. Compared with adults' tall bodies, children will appear weaker. Dogs generally dare not attack adults who are much bigger than themselves, but it is easy to attack smaller children. Because dogs will also measure whether they can beat each other.

third, touch the puppy. If there is a mother dog around, it's best not to touch her child, or she will probably be attacked by her, because she will think that you are trying to steal her child. In addition, when dogs are in estrus or when the weather is very hot, dogs often have aggressive behavior, because estrus or hot weather will lead to emotional instability and mania of dogs. At this time, dogs may even attack their own owners, let alone strangers.
