Dog leash to prevent dogs from scaring others

Owners should pay attention not only to science, but also to civilization when raising dogs. Even if you believe your dog won't bite when going out, it is still necessary to wear a leash for your dog out of social morality, which is a sign of respect and protection for others. After all, the owner is not 100% aware of their dog, and in case of an injury incident, the outcome would be very bad.
