If you came to Beijing before, you'll know it is such a crowded place. I stay in Beijing for a year. Every morning, I can hear dog barking, motor bike running, and I have had a difficult time to sleep. Thus, there is a ban for heavy motor bike too. It will become even more demanding to add more those big dogs to the place. Those dogs are possible sources of noise, will hurt people without proper training (there were many accidents before) etc. They just have enough problem to manage huge number of people, and find a right balance for each body. Probably there is a better solution, but current rule will definitely benefit more people.
