We are going to our third lesson and she will not take any treats nothing, not carrots cherrrios, hot dogs, cheese etc.She jumps at my legs and tries to escape out the gate,[with me attached to her leash.]There is a rather large Boxer there and it barks,jumps and pulls at its owner the whole time, even though it is at the other side of the room.So mine gets semi calmed down,but not enough to learn anything and the this Boxer barks again and mine gets startled and its back to square one again.The Boxer goes to every class,[this class is offered twice a week] and I really feel I wasted my money.What can I do to calm her down? Or learn something besides Mommy takes me someplace that a big monster barks at me? She likes the other dogs, med size and some what larger.And doesn't seem afraid of them.But this Boxer.... yikes and this is that dogs 2nd time to take the class.

What can I do?Help.
