Don't look at her eyes lol. I know, they're killers. I always make a point not to look at Tucker when he's in trouble, because he has those eyes too.
its good that you put her in the crate not as a punishment. I think just feeding her somewhere else is a good idea. Maybe you should try hand feeding her a little bit just to make her realize that the food is hers and she's allowed to eat it.
Its totally possible that she's just getting herself back in order after vacation. I'm sure in a couple days she'll be back to her old self.
