I rescued a Short haired pointer from the Humane Society for my kids. So I half expected some problems but not the Thunderstorm one. We tried everything. The only thing that worked for us was to sit on her, literally, as she tried to get out windows etc. So my sons and I took turns no matter what the time of night. We'd get her laid down beside the sofa and wedge her there with our legs while we watched whatever was on TV in the dead of night.
She was caught outside once while we were all away from the house and we recovered her 20 miles from us. Drugs did nothing. But we still loved her dearly.
