Using your KONG Extreme dog toy is easy. First, you can fill it with your dog's favorite kibble. You can also add a bit of peanut butter, KONG Snacks, and top it with KONG Easy Treat. This will make the toy more appealing to your dog. For a longer - lasting challenge, stuff the toy and then put it in the freezer. When it comes to cleaning, you can simply wash it with warm, soapy water. Just make sure to rinse it thoroughly. Keep an eye on the toy while your dog is chewing. If it starts to show signs of excessive wear and tear, it's time to get a new one. This way, you can keep your dog safe and entertained.
