Using the KONG Jumbler is super easy. Just throw it for your dog during a game of fetch, and the loud squeaker and rolling interior ball will keep your dog interested. You can also let your dog hold it by the handles and shake it for some solo fun. As for care, always make sure to supervise your dog while it's playing with the toy. This toy is meant for light to moderate chewing, so if your dog is a heavy chewer, switch to KONG rubber toys. Remove all the packaging before giving the toy to your dog. If you notice any damage, like tears or loose parts, stop using the toy right away to keep your dog safe.
