Upgraded smart remote control: The interactive dog ball has both remote control and automatic modes. You can let your dog play with the toy independently or choose the remote control mode for interactive play. It has a bite-resistant shell and colorful LED lights to continuously attract your pet's attention. Multiple play modes: You can choose between crazy bounce or normal mode based on your dog's interest or breed, and control the rotation of the vibrating dog ball with the remote control. When the preset mode is activated, the lights will flash and the ball will bounce for 10 seconds, then go into standby mode and activate again when touched. Read the instructions before use and make sure to turn it off after use. Safe and durable materials: This interactive dog toy is made of a robust TPU shell, which is safe and bite-resistant, and can withstand constant play from your dog. Please note, however, that this dog ball is not suitable for dogs with strong biting habits. The shell can be cleaned with water (remove the inner lining first) to keep your dog clean. USB charging: This smart bouncing dog ball has a built-in 500mAh battery and comes with a charging cable for convenient charging. It takes about 2 hours to fully charge and provides 1 to 4 hours of interactive playtime after a single charge.
