Who Trained Whom

Your dog pulls for one reason: pulling works. Every time they lunge toward a smell or another dog and you take a step, they learn that tension on the leash moves you.

There is a second force at work: dogs are simply faster than us. Their easy cruising gait is a trot, while a human walk feels to them like slow motion. So on every outing they are fighting their own wiring, and the leash ends up being the only brake. Pulling is not defiance here — it is a body built for a different speed.
