One tap of the power button and the Rolly Ball takes over rolling, bouncing and changing direction on its own, pulling your dog into a chase that never gets predictable. The glowing ring keeps their eyes locked on it, while the tough, bite-resistant shell shrugs off every pounce, chomp and tumble down the stairs. When the batteries finally outlast your pup, just plug in the USB-C, rinse it under water, and it’s ready for round two tomorrow.
