Ugh.... been there, done that, wanted to puke.
Unfortunatley the best you can do is put the box in a place where the puppy cannot get to it. Would you expect your dog to ignore a big steak you kept lying around? Especially if you are not in the room? You can eh eh, no, shhh, bad dog, all you want but you are talking about an animal and that kitty box has some good sh*t in there!
Get a baby gate to block the way, or put the box in a higher place.
