Someone tried to break into the house and Raksha was barking at them but when she came to me and saw how freaked out I was, her normal "Hey you, shoo!" bark and body language changed over into the fearsome "Stay away from my pack and my home or you'll lose your face!" Cujo version of my pup.
That was surprising and in a detached way, kind of awesome. Though I'm glad she's not aggressive like that normally.
