Should dogs be kept on a leash when walking in public places?

Nowadays, more and more people are choosing to keep dogs, especially residents in cities. Keeping pet dogs seems to have become a fashion. However, if you want to walk your dog in a public place, it is necessary to tie the leash, especially in places with a large flow of people. No one can guarantee whether the dog's temperament will change drastically. If the rope is not tied, unnecessary injuries can easily occur. Just like the incident where a female internet celebrity’s dog bit a pregnant woman was trending on Weibo some time ago, which led to a tragedy and heartbreaking consequences.
