Ah! Neo93 beat me to it. I was going to see if anyone recommended Treibball. Seems like the perfect solution- herding in your backyard. I also agree with the trick training (which ultimately should end up as distraction training) but it sure must be hard to trick train with a dog that is not food or toy motivated. How do you reward him??
