Remote controlled - Just get ready for the interactive dog ball and turn on the switch. Then use the remote control to take control at any time. The interactive dog toy has a built-in motion sensor so your dog can play on his own when you're busy or at work. Plus, the active rolling ball with colourful LED lights will keep your dog's attention. Two Mode Selection - Switch between two modes to suit different dog games. In high mode, the automatic moving bouncing ball moves and bounces quickly. A short press on the on/off button will switch it to low mode, which will usually result in a rhythmic roll across the floor. Low mode for indoor floors and high bouncing mode for thin carpets and outdoor lawns, suitable for different use scenarios. Smart Dog Toy - Works for 10 seconds on regular programme, then hibernates. If it's hidden somewhere that's difficult for your dog to find. The interactive dog ball rolls again to remind your pet to find and play with it when the sleep time is over. Touch the ball to wake it up when it is asleep. Its rechargeable design means you never have to change batteries, so you can play 4 hours on a 1 hour charge.
