Keep your furry friend entertained with the YVE Life Automatic Durable Motion Interactive Rolling Ball Dog Toy with USB Rechargeable. This interactive toy features two play modes that will keep your pup engaged and active. Simply press the blue light button to activate irregular rolling, with 25 seconds of movement followed by a five-second pause, repeating for two minutes. Or, press the red light button for a minute of crazy bouncing, with ten seconds of bouncing followed by a five-second pause. The rolling mode is perfect for hard floors, while the bouncing mode works best on thin carpets or outdoor lawns to reduce noise.
