According to some reports on the Internet, this stray dog has been living on campus and has given birth to a puppy. The reason why the security guard killed the stray dog's mother is because stray dogs have a tendency to bite. The practice of security guards is to protect students and teachers, but this practice is too extreme, which can make stray dogs feel in the way, or directly drive them out of the campus instead of killing them. After that, the school can also ask the counselor to issue a notice, such as not to pet stray dogs and not to feed stray dogs. This is what Bianxiao University used to do, so the students were not bitten by German shepherds.
Man is a perceptual animal. If you can kill other lives at will, it will make people feel particularly cold-blooded and heartless. You can eat chicken, duck and fish, but kill them quickly and don't let them suffer. This stray dog may bite to protect its children, and the school can also keep students away from puppies, so that the stray dog mother can become normal and will not hurt her classmates. In such a big school, it's hard for Niu Niu not to have a stray dog. In fact, many colleges and universities have stray cats and dogs, and students get along well with them.
As adults, students may be bitten by stray animals in natural areas. If they touch stray dogs with their hands, they can be vaccinated after being bitten and then drive them away. There could have been a better solution, but the security guard killed the dog directly, which many people didn't understand.
