PLAY BY THE RULES – SAFETY & CARE: When choosing a toy, make sure to choose an appropriate size/style/level for your dog. No toy or game is indestructible. Ultimately, your pet’s safety is your responsibility. ALWAYS supervise your dog closely, teach your dog how the game/toy works. Do not leave the dog alone with a treat game/toy, do not let the dog chew on the game/toy or pieces. Inspect regularly for damage and remove if broken, or if parts become separated, as serious injury may result. For dogs only, not a children’s toy. When empty, store until next supervised use.
