How To Properly Walk A Dog. In this clip from Cesar 911, I teach a dog owner how to better control her dog on a leash. The first step is teaching her how to properly walk the dog. The key is to have no tension on the leash unless it is required that way there is no anticipation of bad behavior. Remember: aggression is the symptom, not the problem. First figure out the problem and then symptom will resolve itself. | Cesar Millan
