IF you're interested in their health, then, let them set the pace. When they're very young or old, run as far as they want, then walk for a while, usually back toward the house. But, after they reach 9 months to a year, then you can push them some. Trust me, they can take it, and it profoundly effects their physical status in a positive direction, and the stamina you are creating, will hang with them the rest of their lives.

That approach is somewhat like Progressive Resistance Exercising.

Good response this was very helpful
