This ball with robust yet flexible spikes provides hours of fun while also aiding in dental cleaning. The Dog Comets Exoplanet bounces perfectly, floats on water, and is easy to grip thanks to its spikes. These features make the ball excellent for fetching and playing in water. When the dog holds the ball in its mouth, the spikes massage the gums and help clean the teeth. The squeaker in the center adds extra stimulation during playtime.
