Redirected Aggression in Dogs

husky attacksAs any police officer can tell you, domestic violence calls can be tricky. The officer arrives at the home where a couple’s heated argument has progressed to violence. But although the two have been screaming at and even hitting each other, when the officer arrives, a strange phenomenon occurs. The target of the violence suddenly shifts to the officer.

Now consider two dogs who are fighting in the home. What started out as a skirmish has escalated to the point that the owner feels the need to step in. She approaches and tries to grab one of the dogs by the collar. The dog whips around and bites her on the arm. What’s going on here?

Both scenarios are examples of redirected aggression. Emotional arousal becomes so intense that it needs a release, and the target shifts from the original opponent to the source of interference. That’s one reason so many people are bitten when trying to break up a dogfight. It’s something most of us learn the hard way, and I’m no exception; I could show you scars.

Redirection doesn’t only happen to third parties, though. It can erupt between two dogs when caused by another. For example, a Labrador Retriever and a German shepherd are at the dog park, happily romping and playing together. A Boxer comes along and approaches the pair. Suddenly, bodies become stiff. Tension is in the air. Just as the Boxer and the Shepherd are cautiously checking each other out, the Lab slaps a paw over the German Shepherd’s shoulder as if to say, “What’s up? I thought we were playing!” The Shepherd turns and lashes out at the Lab. Again, the tension needs a target, and in this case, instead of being focused on the cause of the tension, it’s redirected to what drew the attention away, much as a lightning rod diverts lightning from a structure.

A common scenario for redirected aggression is when two or more dogs are behind a barrier, such as a chain link fence. Someone passes by the yard with another dog. The enclosed dogs begin to bark and jump at the chain link. They can’t get to the dog, so they become agitated. Frustration builds. When it reaches a boiling point, the dogs may redirect on each other. Barrier frustration can easily turn to redirected aggression in other scenarios, too: picture two dogs who both want to go out to the yard because they see a squirrel. They jump, whimper, and claw at the sliding glass door that leads to the yard. Frustration builds, and soon they turn on each other.

Anytime there is over-arousal, aggression can follow, and it will find the most convenient target. So what can you do to avoid redirected aggression? Be aware of the potential. Try to avoid putting your dogs in situations where redirected aggression might occur. If you see a situation building, interfere before it’s escalated too far. Teach a solid attention cue, meaning your dog stops whatever he’s doing to look at you when you call his name. Don’t jump in to the middle of a dogfight and expect not to be bitten. (How to properly break up a dog fight is a whole other blog.) Don’t approach dogs behind a barrier if they seem agitated; if they are calm but then become agitated, leave. In many cases, redirected aggression can be avoided. The more we understand about how dogs think and react, and the more vigilant we are about recognizing their body language and actions, the safer we can all be.

  1. Thank for another good article! Redirected aggression seems to be a very misunderstood phenomenon. I’ve heard many people say that one dog is trying to scold the other dog, or that it is a tolerance thing — (i.e. I can’t stand listening to you any longer! Chomp!)

    One thing I’m curious about is why redirection is selective. For example, in a multi-dog household, a dog might redirect on one dog but never the other dog. Or a dog redirects on anyone that is close but never the owner…

    I have a deaf Aussie that always directs his aggression towards one of my other dogs. It is difficult to gain his attention to stop the fight because of his hearing deficit. Any suggestions?

    I am currently re-reading Lorenz’s “On Aggression” Chapters IV and V he does a pretty good job of explaining ‘redirected aggression’ and the ‘aggressive instinct’.

    I had my rescue re-direct onto me 2 weeks ago when I was trying to keep her away from my Staffie. Very painful deep bites! Good job she is only a small pug cross. She now wears a drag lead in the house just in case I need to remove her from a situation. I know the trigger points now and will try to avoid them. She deserves a chance.

    This is such good advice! My GSD has a buddy, Hector – a boxer. He and Hector have a great time when they are together. Until I read this article I didn’t understand why it is that when a third dog joins them, Hector always growls at my dog and then starts a fight with him.
    After the first couple of times I’ve handled the situation by calling Jake to me and having him sit until Hector simmers down. It just felt like the right thing to do but I didn’t really know if I was doing the right thing or not.
    Can I ask a question? Perhaps you can address it in another article. We have some very aggressive dogs in our neighborhood. Usually they are behind a fence. They are very aggressive towards him, but from behind the fence. My dog ignores them completely when they are behind the fence, but if we encounter them when we are walking– and they are walking– he barks like a maniac at these specific dogs. This is because? Thanks!

  6. Thanks Nicole, always enjoy reading your articles.
