She is most likely trying to establish the dominance of the pack, some dogs act stupid and go overboard.
You need to dominate her often. Let em all know you are the dominant pack leader, and that particvular dog needs it alot more often than the others.

My decision would be to "be the leader" and take all the guess work out for the pups. Establish this in your pack, and if the dog challenges you then you know the dog has serious issues.
