If you are concerned that your puppy might get into trouble and you wouldn't be able to hear him, you might consider purchasing a break away (cat) collar for him with a bell attached. My Daisy wears one.....I swear that I can tell what she is doing just by the little jingle noises.....it clangs against her bowl when she eats, it makes a huge racket when she plays with the cats, etc.
