Thank you Jeane. That is reassuring. That is what I try to do - matter of factly when leaving Lexi but I am sure she can "feel" my emotional upset as I feel SO guilty knowing what this does to her.
I have a Shih Tzu that we got at 6 mo. & he is very high anxiety. He was kept in a cage pretty much his whole first 6 mo. before we got him and so was horribly fearful of being left once he came into our home.

He also got better but still has SO much anxiety over not only "bad" things (what he perceives as bad) but good. He is fortunately not destructive or peeing or vomiting when upset. He is 12 y/o now. He has come a long way but still has emotional issues. So sad as it should have never happened in the first place. He is on Prozac for it.
