Extra great and handy for kids to use. The children tend to get pulled around because the dog gains momentum before the children take up the slack of the lead. By that time, the kids either have the lead pulled out of their hand or get dragged behind. Either way you have a lose dog and/or an upset child. This way the kids have their hands on the dog preventing that momentum. Helps out with those dogs that are just bigger or stronger than your kids but they still want to help walk the dog. This way you can have control on the lead and the kids can hold onto the harness handle. Certainly can make walking the dog an enjoyable family thing to do.
