With this toy, the name says it all. The full rubber Bouncer balls bounce and jump unpredictably in all directions when they hit the ground. This creates a surprise effect every time and encourages the dog to chase after them. The brightly colored balls are therefore a great toy for keeping your pet entertained and provide plenty of interactive fun for both dog and human. Additionally, they are very durable and can withstand many rounds of play. The balls are delivered in a color-sorted display.
