For outdoors SuzyQ loved her nylabone frisbee. The last one I bought was about $17.00, but they last a long time. She was obsessed with this and loved for us to throw it for her, but also played with it by herself. She would kick it and chase it and stomp on it, barking all the time like a maniac. She would do this till she wore herself out and had to lie down and then when rested start all over again. Whenever I wanted to work outdoors, we just found her frisbee and she was good to go. We used to have a german shepherd that found an old bowling ball in our garage and that fascinated him, he couldn't get his teeth in the holes to pick it up and would chase it endlessly around the yard.
