Hi, first time 'poster' as I have a dog problem which I'd like some help with. Two weeks ago my lab x border collie was freaked out by a hot air balloon which came low over us out on a walk and then landed in a field. The dog ran off - first time he's ever done this, never usually goes out of my sight - and we lost him for 8, very stressful, hours. Was found at the other end of our village, but wasn't tired or hot, (would love to have had a GPS collar on him!) so we think he was very traumatised and just hid for most of the time. Since then he has been unsettled, particularly in the house, growling/barking at smoke alarms, ceiling roses, round ceiling lights. We've covered these up now, but he still finds other objects to growl at randomly.. When he goes in a room in the house he keeps looking around at the ceiling. Went to someone else's house and he barked at their round kitchen light. Do you think this behaviour will wear off? Any help gratefully received.
