Jacks need a lot of exercise. Why not take up Flyball or Agility? I often am able to do a little caching at the parks we compete in. In fact, I looked again for a cache this weekend at a flyball tournament in San Diego , that I again, could not find. ,when it had been found recently.
I agree. We've taken our dogs to 3 levels of Obedience classes. Our next step is Agility. We start later in the Fall. To give them exercise we take them to our local park twice a day and let them chase a ball or frisbee. I'm the only one who gets exercise from geocaching ... which isn't saying much for my fitness level.
