The SmartPoopy Walking Bag dispenser conveniently attaches to the handle of your leash. The bags are also biodegradable and compostable. But who wants to walk around their neighborhood carrying a bag of dog poop? The bags are extra long, similar to the rain cover for a newspaper. This allows the bags to be half-knotted and hooked onto your leash attachment. Thanks to its large size, it's possible to use the bag multiple times on each walk.
