A Word about Harley....

This is Harley, my identical twin sister

I love my sister; I really do. Harley is my twin and my best friend. She's been right beside me all of my life and I don't know what I'd do without her.
(I know, you're waiting for the "but").
Harley has a disability. You'd never know it by looking at her, because she's an almost perfect looking dachshund, just like me! (We ARE identical, you know).
Lately, her disability has almost overwhelmed Mama #2. Yes, Harley's anxiety is spinning (or barking) out of control.
For the past 4 nights, at almost exactly 1am, Harley begins barking. And Barking. And barking. And barking.
She runs outside and barks. She ignores Mama #2 and Mama #1 when they ask her to come in. 
She runs from Mama #2 when she gets dressed and goes outside to find her. Maggie sometimes goes outside and joyfully barks with her. Maggie also runs from Mama #2.
I, your favorite Diva, resist the urge to join them. I merely stay inside and behave myself.
When Harley is finally captured and brought inside, she still barks. She runs from room to room and barks and barks.
The Mamas do their best to calm her down. I even suspect Mama #2 has tried to tranquilize her! (Why else would she give Harley a treat after she acts so badly?!)
About 2am  Harley usually calms down and everyone tries to go to sleep. Once Harley gets back in bed, crawls under the covers and sighs deeply, I creep over next to her and put my paw on her. I don't understand and she can't explain to me why she goes off like this. 
We need to find her a really good dachshund psychologist. I'm losing sleep over this.

Here I am, trying to counsel my sister. (I'm on the right side. I'm the relaxed looking one).
