Obedience for life. It doesn't stop once they finish a class. Continue to take her to class. Of course she is going to run all over the place acting crazy because she is on a leash all day. Do you own a crate? You can't have her on a leash for the next 12 years. If she is living in a house with other dogs, your going to have to work with all of them do they can co-exist. It's not fair to her.
