Welcome to the USA Dog Behavior podcast! I’m Scott Sheaffer, here to help you understand the fascinating world of dog behavior. Today’s episode: Why Punishing Dog Aggression Backfires in the Long-Term

 I get a lot of questions about handling aggressive behaviors in dogs, and one thing I hear all the time is, "When I punish my dog for being aggressive, it seems to work—at least for a while. Why does the behavior end up getting worse later on?"

I understand your dilemma. You’ve got a dog that’s snapping, growling, or worse, and you’re frustrated. You just want the behavior to stop. It’s completely natural to want to step in and do something about it, and punishment can seem like a quick fix. In the moment, it might feel like you’ve solved the problem because your dog stops what they’re doing. But here’s the thing—what seems like improvement now can backfire later.

Let me explain why.

This is why Punishment Seems to Work Initially

When you punish a dog for acting aggressively, whether it's yelling, leash corrections, or anything similar, you’re often seeing what’s called a "suppression" of the behavior. Your dog might stop growling or lunging because they’ve learned that those actions get them into trouble with you. In other words, they’ve learned to hide the behavior in front of you or in certain situations. 

On the surface, it looks like progress because the aggressive display has stopped temporarily. What’s really happening underneath is that the emotional state—fear, arousal, or frustration that was driving the behavior—is still there and possibly getting worse. Punishment hasn’t changed how your dog feels, only how they express those feelings. And that’s where things get tricky.

This is the Long-Term Problem with Punishment

Dogs, like people, have emotional thresholds. They can only hold in their stress or anxiety for so long. When we punish dogs for displaying their discomfort, we're teaching them to bottle it up until they can’t take it anymore. This bottling up is technically called masking, and eventually they’re going to explode—usually in the form of even more intense aggression.

Ian Dunbar, internationally recognized animal behaviorist, says “Dogs that are bottling up their fear, arousal, and frustration are nothing more than ticking time bombs.”

What makes it even more concerning is that this bottling up process can lead to unpredictable behavior. You’ve now got a dog that isn’t showing clear warning signs anymore (growling or snarling), so it’s easy to think everything’s fine—until, suddenly, it’s not. When that built-up frustration or fear hits a boiling point, your dog may lash out in a much more dangerous way because the underlying issue has never been resolved.

And lash out with little or no warning. Punishing aggression in dogs is nothing more than a really bad Band-Aid.

So, What’s the Better Approach?

If your dog is showing aggression, the key isn’t to shut down the behavior with punishment but to get to the root of why it’s happening. In other words, aggression is merely a symptom of a deeper problem. Usually, aggression stems from fear, anxiety, or a sense of being overwhelmed (i.e., over-arousal). By focusing on helping your dog feel safe and teaching them alternative ways to cope, we can address the problem at its core.

This can involve things like desensitization, counterconditioning, and management techniques that change how your dog feels about the triggers causing their aggression. It’s not about suppressing the behavior but transforming the emotion behind it. 

It’s a longer process, sure. But it’s far more effective and humane, and it builds trust between you and your dog. Instead of shutting them down, you’re teaching them how to handle the world around them in a way that’s safer for everyone.

My Final Thoughts

I know how hard it can be to live with a dog that shows aggression, and I understand the temptation to use punishment because, in the moment, it seems like it’s working. But in the long run, it’s doing more harm than good. If your dog is struggling with aggressive behaviors, take a step back and work on addressing the real issue. You’ll end up with a happier, safer dog—and a stronger relationship with them.
