pidan proposes a simple yet ingenious solution to the common problem of a dog straining on a leash. By exploring the elastic trait of basic geometric figures, the designers effectively combined the decorative and the practical. The buffered rubber module in the middle of the leash changes shape to absorb force when a dog strains forward, thus mitigating any injury to owner or pooch. The rubber module also has a handle function, useful for pulling the dog close in an emergency.
