Flyball is an activity you'll need classes for, you can go here and search Flyball in [your area] and see what it comes up with. I think Rita would love doing Flyball as long as you keep her active and healthy. You can also make a simple flyball machine at home after you get into classes. The reason you need classes so bad for flyball is because they teach dogs specially how to get the ball and trigger it and all that. Hope I could help you and Rita out
