The Kong Bunji High-Viz Bright and Glow-in-The-Dark Retriever Rubber Ball and Rope Dog Toy - Assorted Color offers erratic bright, high-contrast colors and raised ridge design for erratic bouncing. The built-in bungee cord launcher with loop handle allows you to fling this medium ball far without much effort, and it makes tug-of-war retrievals easy too. Like its larger counterpart, the medium Bunji Ball glows in the dark after a short charge and floats on water, making it a versatile fetch toy from dusk to dawn, land to lake. Medium dogs get to enjoy the shoulder-saving, high-flying fetch thrills and interactive tug fun scaled to their size. Available in Multiple Sizes
