I need some serious help! I've had my rescue setters for two months. The last three nights have been a nightmare. Last night at about 2:00A.M. he suddenly started howling. When I found him he was shaking and acted as if he did not even recognize me. I comforted until he calmed down and I stayed and comforted until 7:00 A. M. Two nights ago he growled and barked and my wife stayed up for hours comforting. We put on his thunder shirt and played "music to calm dogs". which worked as well as anything. Does anyone have any ideas? Is he having flashbacks? Help!
