My toughest task yet. In this clip of Cesar 911, I meet a dog that bites an innocent bystander. Could this be the first dog that I can't help? Stella is a Weimaraner with a killer instinct. She attacks dogs and humans and if the issue isn't deal with right away, I fear something terrible can happen. | Cesar Millan

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

It's been quite a season. Lots of intense stories, tough cases, tears, lessons, and laughs. I hope you'll end the journey with me by watching the finale tonight, and sharing what you've learned. 9/8c on Nat Geo WILD. #Cesar911 | Cesar Millan
