The leash is really great, so does our dog with a beautiful 10m radius. It all works very well, the belt is about 2 cm wide and thus extremely stable. The only downside is the high weight - the leash weighs just under 1 kg. A lighter line is already more pleasant for children even better. We have but the city was still a 5m Gurtleine that is as practical and of course much easier. But perhaps you could make the 10m-line with a narrower belt, which would be easier ...? That would certainly be better for our Beagle (13kg), because here I put the leash even with a harness on. For a necklace of train would certainly be too strong.
