Have you ever thought of taking her to obedience or like primabella said, agility?
I took Roxey to obedience school & she just loved it, it was her favorite thing in the whole world to do. She would know when Tuesday came, we were going to school! We went many times, even though she didn't need to go again, we just went because she liked it so much. We also went to an agility class. We had alot of fun.
