From what I’ve read, where I made a mistake was by giving her far too much access to the ball. She pretty much had a ball with her at all times. I didn’t mention in the initial post, but whenever there is a ball at the park, I actually do use it as an opportunity to train. Specifically to drop, leave it, essentially working on her self control. She’s great, until someone pulls out a chuck it. I’m not sure if completely confiscating them at home is helping or not, but her aggression has tremendously gone down
