The Double-Dog Leash? is the world?s first totally adjustable dog leash for walking two dogs! You have the option of walking two dogs close together, two dogs far apart; or two dogs of different sizes. This original leash product allows owners both safer, closer control on crowded streets and a more free, wider range during park walks! The Double-Dog Leash? straps are made of quality nylon webbing. All parts are made of durable custom nickel-plated steel for reliable strength and reduced weathering. The Double-dog leash features a no-tangle design, and the patented Sporn Adjusti-Buckle.
