How many times can you throw the ball and it's still not enough. Dog's have a lot of energy and need exercise just like we do to keep in shape so they like a long healty life. AirEarthFire has the solution for all hyper and elderly dogs with our suction cup ball and cord (elastic too) for hours of endless fun. We dare your dog to try and pull the suction off. With a clean smooth surface and tight suction, he/she is just not getting that cup off no matter how long they try. The can also be used for outdoor throwing, just be sure to not let them chew on the suction part in either situation which will degrade the suctioning strength. The make great gifts and come in 3 colors. FREE SHIPPING ALWAYS.
