About this item More interesting is the plush monster: the interactive ball automatically shakes and lets a simulated dog bark to attract dogs to play. By shaking it or touching it hard, it will be reactivated and help your pup enjoy it and have fun. Removable and Washable: We offer two high quality plush covers that use the two safe and non-toxic materials for chewing pets. Suitable for indoor and outdoor play: the dog ball accompanies your pet like a friend when you are busy. Easy to use: Just shake it and automatically bark for about 12 seconds until your dog’s next tap is activated. Just put 3 AAA batteries into the activation ball and you can play with your dog for a long time. The internal electronic ball is not a chew ball.
