flexi Vario is a high-tech dog leash that offers flexibility, security and comfort for both dog and owner. User-friendly operational features include the short-stroke braking system, customised handle size settings and a coupling system for attaching interchangeable belts, for example; the Duo Belt allows you to walk two small dogs together. The LED lighting system with a front and a back light illuminates the way in the dark, and a multibox stores treats or poop bags.
