Hi. I have a 6 mos old GSD cross with a maremma and he's huge...or at least everyone I meet thinks he is. He's definitely not small and he's extremely strong. I was thinking of training him to pull a cart (or a sled, in winter). When is it safe to start them pulling and does anyone know how to train them to know directions like in that movie "Iron Will"? You know so you could say "Gee" and he would go left and "Hie" and he would go right or something like that?
I think he'd be great at pulling because of his immense strength and it could get him some extra exercise at the same time. Any help would be great.
