3. Do Road Work
Snell's favorite off-season workout is roading: He attaches a roading harness to his dog, which, unlike a collar, distributes pressure across the pup's chest, encouraging it to pull forward. At the same time, Snell pulls back but allows the dog to cover ground. The resulting tug-of-war can last for a quarter mile or so. If you're not looking to break a sweat, roading can also be done on horseback or ATV. But stay away from paved streets, as the asphalt can tear up paw pads.
