Expanding handsfree-leash with expanding belt leaves hands free to allow for pole walking. The leash is made of strong nylon.
The leash was specially designed taking into account the discomfort and injuries that the dog and owner may experience if the dog lunges and pulls on the leash.
Dogs who pull hard on the leash not only strain their own neck and back, but also the owner’s wrist, arm and shoulders. The expander absorbs this load.
