Im not sure if you posted this but do you leave her door to the crate open ? I ask this because all mine are crate trained but i do not shut there door, they use there crates for napping, go in & out as they want to. I do how ever shut there door while im away, for there safety

im never gone more then 2-3 hrs tops. but i know what can happen in a short time . also there crates are in my living room, so there never really alone
