Mz Tillie, the bulldog, does that at least once a day to me. Of course I'm mostly deaf and without aids turned up max, it could be true.
We live close to an ambulance/fire truck route. Not only does Duke hear their sirens before we do, he hears them before they are turned on.
Trust me, Duke hears stuff before it happens.Before it's turned on there is nothing to hear.
he can hear the darn diesel engines starting for miles. After they start, the sirens come on.Before it's turned on there is nothing to hear.
