Do I need a leash to walk my dog on the rooftop?

Need. Because it is for the safety of passers-by to lead the dog to walk the dog, although the dog is human, it is still an animal with low IQ after all, and it is not as easy to control as human. It is very dangerous and unsafe to walk the dog without tying the rope, so it is necessary to tie the rope everywhere, which is also for everyone's safety, so it is necessary to tie the dog on the roof. Taking a dog for a walk is the most basic quality of dog owners, which can avoid accidents such as lost pets, eating poison by mistake and car accidents.
