Beau is exactly the same that I am thinking of re-naming her Shadow!! My trainer said that I am building on her anxieties by not leaving her because I worried about her crying so I started to leave her for a few minutes at a time and built on this. I leave the radio on and give her a kong filled with frozen yoghurt, treats, apple, peanut butter etc. I also make sure she has plenty of toys. She still cries a little bit when I leave as have stood at the kitchen window to listen to her but it doesn't last long. The trainer also said when I come in I should ignore her for a minute or two so that me returning is not a big deal. It is hard but it does get easier and it is for her own good as well as yours. Good luck
