In spring, a young dog's fancy turns to all the new scents in the air. A dog's absolutely favorite way to experience the natural scent of skunk and horse dung is to travel astride his owner through the countryside on a bike. A speedy bike like a Harley®, for example, makes a friction of the wind like nothing else he could experience. A motor scooter will do, or just a plain old pedal bike, if it comes to that. But before getting on board, your biker dog must be able to make just the right fashion statement.
