..Have you tried leaving her not in a crate?
Our youngster is a naughty little monkey half the time but I have never locked her up when I go out. She will just find somewhere to snooze where she feels safe and has never done anything when we're out. I often wonder if some dogs feel stressed when they are in a crate and they know there is noone available to open it if need be. ?
Just a thought. I know there are two camps on the crate issue
(rest assured ours will be off with your handbag as soon as we are there though!...)
