Samantha has a couple...

* barks at anything out of the ordinary
* doesn't "come here" unless it's her idea
* when she gets loose (which hasn't been for over a year), she will not come at all - she'll just run around because she thinks it's a game
* she jumps up on you if she's outside and you join her
* still tends to revert back to play biting when you play with her, though she is getting better
