My fog is fine being left home alone, (I've recorded him several times) he watches us until we're out of sight and then he lies in his bed and sleeps.
Until he hears the car approaching. Then he jumps up into the bay window, barking and whining until we get to the front door. The thing is, he's got a very big, deep bark. Neither of our next door neighbours have ever commented on this, the neighbour we're attached to will definitely be able to hear him (we are able to hear NDN turning light switches on/off!) but we suspect he's dead and the NDNs we're not attached to would definitely be marching straight round if they heard barking.
Is it possible to stop the barking? He doesn't do it if we approach the house on foot as obviously walking isn't loud like a car and there's no faffing about reversing onto the drive and straightening up etc so by the time he's realised what's happening and got excited we're already in the house.
