Wow... You definately have reason to be concerned, especially when it comes to your children. What do you all do when she acts this way? Is she told a firm NO or put on "puppy time out" (as I call it) when she acts out? Do you assert your authority as the "alpha" dog in your home? If not, then this is why she acts this way... But, Im not the expert and I havnt had a pup act this way. I would definately try to get a trainer if you can afford it... Or even perhaps a book that addresses this behavior in dogs, might help get you in the right direction. Sorry for your troubles & hope this helps
