Intelligent interactivity: This dog toy ball has a built-in intelligent sensing system, which attracts dogs to actively chase and play through unpredictable rolling and sounding, saying goodbye to boredom and keeping your pet active and curious at all times. Bite-resistant and wear-resistant material: Made of safe PC and TPR materials, the side of the ball is designed with wear-resistant cotton rope winding, which can not only help clean teeth and massage gums, but also satisfy the dog's chewing nature, which is very suitable for teething puppies and medium-sized dogs. Three modes free switching: Provides three modes of "fast", "slow" and "interactive" to meet the needs of dogs of different sizes and personalities. The chirping sound is turned on by default, but when you need quiet, you can quickly press the button twice to turn it off. Touch-activated sensing: Tap or touch the nose to wake up the toy and automatically turn on the interactive mode. It goes into sleep mode when idle to save power, smart and worry-free. Waterproof and anti-fouling material, you can play indoors and outdoors, and cleaning is easier! Convenient USB Charging: No need to frequently replace batteries, the smart dog toy can be charged via Type-C cable, making it a worry-free choice for on-the-go entertainment.
