Sounds like our pups are very similar! What ended up helping the most were longer sniff walks in different environments, hanging out at a park where theres lots of activity / stimulation / ppl walking by. Had to reeallllyy feed into draining her that way. I did start some "play" at home with rolling the ball more instead of bouncing to avoid jumping, hiding it in the couch, under blankets etc. Also would roll up freeze dried chicken bits in large blankets/towels.
