I think that is a waiting game. If she knows she will get you if she acts like that, she's got you...
Buy a crate....then put her in a sound proof room till she gets used to it...
We've got a crate. She does great in it when she's tired. Even if she sleeps for a few hours and wakes up, she'll just chew a bone or hang out in the crate until we let her out.
But what just happened was something I've never seen. The dog lost it. I just watched a video on training dogs to deal with separation anxiety. We'll try a few of the tips.
Essentially, the video said to place the dog in an area (like the gated area of our den) and spending a few minutes. Make sure the dog is calm, give it a command like "I'll be back soon" and walk away. If it goes nuts, walk back to it, don't pet it, and allow it to calm back down. Each time, spend a little longer away from the dog before returning. If it can always get back to being calm, it should get to the point where the dog won't freak out as much or any at all.
I'm sure I'll be back to report what happens and report any new oddities in my life.
