Someone said it here years ago, but basically without a good dog a burglar/psycho can be at the foot of your bed without you even knowing it...... We have 3 and they usually perk up as soon as they hear a car hit the gravel driveway a couple hundred yards away.

Every once in awhile my wife will “hear” something in the night..... I always reply “are the dogs barking?” Then I go back to sleep. Glad everyone is OK.
