I used to do something similar with the ball. I would find a park with a baseball field. We would go onto the field, and I'd do the same as you minus the walking as I threw it. We would do that for about an hour. That same dog was run around bean and rice fields. I didn't own a mill then so the dog just ran with my car around those fields.

We had another dog that wouldn't do any of that. A friend and myself would kick a basketball back and forth while the dog chased it. That was how Mike was shaped.

I also use more resistance devices now.
