Not to mention that leash is really hard to hold on to! We use it when Niņo goes to the park to run around or if we go out to the forest preserve or if he's in the front yard. I see a lot of people at shows using it to exerscize their dogs in the grassy areas, andI think it is very good for it, too. I hate it when people walk their dogs on them and their dogs runn all over in people's yards and they have no control.
