Using this KONG Bacon and Cheese Easy Treat is super easy. First, take your KONG Classic or other rubber toy. Use the uniquely designed nozzle to control the amount of the treat and fill the toy. You can also top a stuffed KONG with this treat. If you want your dog to have a longer - lasting challenge, put the stuffed KONG in the freezer. There's no need to refrigerate the treat itself. Just keep it in a cool, dry place. When using, make sure the nozzle is clean to ensure smooth dispensing. Always monitor your dog while it's playing with the stuffed toy to prevent any choking hazards.
