Recently, my dog started to "freak out". When I go to put her into her kennel, she gives me a wierd look. Then, when I go to close the door to the kennel, she jumps toward the door while growling, barking, and what seems as if she is trying to bite me. My questions are: 1). What could have caused this, 2). How could I stop this, 3). Do you think she would attack me, and 4). What should I do if she does attack me
