the dog certainly doesnt need to be attached to a cart to be trained to the feel of the harness....that is done by attaching something like a mlik jug for some rocks in it and then slowly working your way up to pulling a cart
My friend put her pup in a harness at a pulling show just to see how he would react. It was attached to a cart with a lot of weight on it, she was just seeing how her pup would do in a harness. It was there, she was there, so, she hooked him to it. She didn't ask her dog to pull anything. That was my first thought when I saw the photograph. But, it seems as though we'll just have to agree to disagree on this one.
