The unique advantage of the Flexi Black Design roulette leash is freedom for the dog and the owner. The dog moves freely - but at the same time he is on a leash. The owner controls the dog at all times, regardless of the length of the leash. Thanks to the always slightly taut belt or cable, as well as the built-in braking and turning system, the Flexi leash can be controlled with one hand and the owner always keeps the dog under control.
