We crated her last before going shopping night and she went berserk. However she has wandered in and out of her crate in our presence seemingly without a care in the world.
We crated her again this morning before going to work and when OH got home at 2ish, there was no sign of distress or unrest.
Also, in the last day or so, she's following us around less.
A friend of mine had a rescue dog that suffered from separation anxiety. He used to chew the doors when she went to work. She got him a cage that he could be in during the day and they went to dog agility classes which helped a lot.
