If a chained dog barks and scares people or some perverts are scared when they see a dog, what responsibility should the owner bear?

I understand you very well. Golden retriever is the most docile dog, but many people who don't know or like dogs make a fuss when they see its big size. I can't help it China people have this quality, and quite a few people don't like dogs. Unlike foreigners, most people like dogs very much. In fact, it is particularly inconvenient to keep a dog in a building. When I used to keep a dog in a building, I was very careful when I walked the dog. I listened from all directions for fear of scaring anyone. Later, I moved to the suburbs and rented a big yard to live in, so dogs could run around at will. Even if I take my dog to play outside the yard, the local farmers are used to dogs because they have dogs at home, so there will be no such trouble. Now think about it, dogs should have a yard.
