A popular sport in Germany encourages dog lovers to bring Fido along for some weekend exercise and fun.(19)Volkssporting translates from German as the " sport of the people" and its most popular form is organized hikes, known as volksmarches.
    The only special "dog rule" is dogs must be kept on leashes. Many owners find a morning or afternoon spent hiking together is good for the dog as much as for the human members of the family. All breeds are excellent candidates for volksmarching, since walking is an activity natural to dogs.
    These marches in Germany are offered year round in dozens of towns and cities every weekend and typical distances are 10 and 20 kilometers. Some volkssporting clubs offer extremely long distances, too.
    All volksmarches are not limited by time.(20)Ask avid marchers why they love the sport and you’ll get answers ranging from how healthy it is to how it feels exciting to get outdoors in the fresh air.
    Camera lovers often shoot the scenery as they hike and this is part they like. Trails might wind through the Black Forest, parallel the Rhine River or go right through the middle of a city.
    Since the sport is not competitive, all finishers "win" and each human receives a medal or other specified prize such as a decorative cup.
