The whole point of playing dog sports with your dog is that you can bond, have fun and keep fit all at the same time. You could spend just an hour a day playing and enjoying yourselves and still benefit from it all. However, if you do not have time to set up the various equipment associated with dog sports like obstacle courses and search and rescue, you can play more simple games like fetch. Fetch is an old favourite that is a dog sport purely and simply because it requires a lot of energy, but can easily be played on a walk or even in your backyard.
