Your comment about your chasing your dog brought back memories of the Saint Bernard we used to have. She would run off and then wait for us to get close to her and she would run off again. She would play this game for a very long time. Finally, one day I remembered that we had left over popcorn from the night before and that it was one of her favorite treats. I sent one of our boys back to the house to get some and sure enough Moosie came running back for a treat when we called to her that we had some for her. Memories are wonderful. She was the best of all the dogs we had over the years.
