Dog aggression: what it is and isn't.

Does your dog's behavior seem aggressive? You're not alone in wondering this. Many times, what appears to be true canine aggression is simply a reaction to a lack of leadership, structure, and accountability. As a dog owner, you are your dog's leader, and they look to you to set the boundaries for acceptable behavior.

Aggression vs. reactivity

True aggression is relatively rare. What most owners experience is reactivity: a dog who barks, lunges, growls, or pulls toward triggers because they are uncertain, fearful, frustrated, or overstimulated. Leash reactivity, for example, often disappears once a dog understands what is expected and trusts the human holding the leash.

Aggression, on the other hand, is behavior intended to harm or intimidate. It can be rooted in fear, resource guarding, territorial instinct, or inadequate socialization. Both require professional assessment, but the path forward is different for each.

Leadership is the foundation

Dogs do best with clear, calm leadership. When rules are inconsistent or boundaries are unclear, dogs often make their own decisions — and those decisions can look aggressive to us. Simple daily structure helps a dog relax: predictable walks, clear commands, controlled greetings, and boundaries around food, furniture, and doorways.

What you can do today

• Stop rehearsing the behavior. If your dog reacts to other dogs on leash, avoid close encounters until you have a training plan. Every reactive episode reinforces the pattern.
• Control the threshold. Work at a distance where your dog notices a trigger but does not react. This is called staying "under threshold."
• Be consistent. Everyone in the household should use the same commands, same rules, and same consequences.
• Get professional help. Aggression and severe reactivity are not DIY projects. A professional trainer can identify the root cause and build a plan that keeps everyone safe.
