With Summer's dstractedness a lot has been my new trainer really forcing me to notice issues. I'd get lazy at class and just let her out, march over to the start line, then call her. Or after a run Summer would go do a lap or 3 or jump on the x large crate (she loves climbing it for some reason). Or she'd go try to make friends. I just didn't pay it much mind because well... when I'd call her, she'd come, stay, and go do her agility thing.
But now I am very very aware of her when we are going to and from the crate. She is not getting to go wild and free between runs even though she was not causing any problems, it was making her think it was okay when we weren't working to be a lunatic. It was also giving her practice switching sides on me, which was coming out in our runs. So now when I get her out, the focus is 100% on her and keeping her engaged all the time and keeping her on one side of me.
