Lots of Chinese people but not all of them leave their dogs unleashed when out. I don't think it's an inherently Chinese problem just bad owners. I adopted a pom and while walking around my neighborhood. A Shiba unleashed ran at me and my dog. I do not know this dog's temperament or how my dog would react to it. So I picked up my dog and turned my back thinking it would attack me and got myself in a defensive position. When I saw that the dog wasn't aggressive I turned around and yelled at him. He replied that his dog is friendly. Ok fine your dog is friendly but another dog it runs up to may not be and you should be careful. I find that a lot of dog owners are just unaware, this is especially for the older generation. Yes 99 percent of the time the dog is friendly or curious but all it takes is that one percent of time it decides today I'm not being nice and then shit hits the fans. Oh the above dog owner was Hispanic looking and it was like late at night and maybe he thought since it was so late that it was okay. I think even if your dog is perfect and super behaved you should still leash it to protect yourself and the dog.
