Leash Aggression
What is Leash Aggression?
Leash aggression is the barking, growling, lunging, spinning, pulling and/or excitable behavior that your dog does when she is on-leash and spies another dog or other trigger. This behavior can be embarrassing, frustrating and very worrisome for you, the owner, and can turn walking your dog from a pleasure into an absolute nightmare.
Leash aggression (also sometimes called Reactivity) happens only when your dog is attached to a leash, and dogs can display the leash aggressive behaviors towards many things, including dogs, people, bikes, scooters, cars and small animals like cats.
Leash aggression is a very common issue in a society where dogs must be on leash for safety and legal reasons. You are not alone if the above descriptions sound just like your dog.
What are the Causes of Leash Aggression?
Leash aggression generally has three root causes:
- Your dog is a social butterfly who gets overly excited and/or very frustrated when she can’t access that dog or person across the street. The leash is preventing her from going where so wants, she can’t cope with the frustration and WHAMO! The frustration builds up until your dog just loses it.
- Your dog is worried, fearful or nervous of the dog, person, etc. she sees and the leash causes a feeling of restraint. Your worried dog feels like she cannot get the distance she might normally choose from the source of her fear, or offer appeasement signals, or do some of the other things she might naturally do to communicate, “I’m not a threat and I don’t want to fight.” Because she feels restrained, she goes into defensive mode and that’s when you see all the barking, lunging, growling and carrying on. Your dog is essentially saying, “GET AWAY FROM ME!” with all that naughty behavior.
- Your dog has some degree of prey drive and the cars, cats, rabbits, moving bikes and/or scooters trigger that instinctual drive to chase. The leash prevents the chasing behavior and your highly frustrated dog is left with nothing to do but bark, lunge and pull dramatically towards the source of her frustration.
- In some cases, leash aggression can be a combination of the above.




The Myth of Socialization and Leash Aggression
You may hear or read that you need to up your socialization game in order to “fix” or help your dog. This cannot be further from the truth.
More exposure to the things your dog feels worried, scared or overly social about may do more harm than good and we do not recommend doggie daycare, dog parks or trying to have your leash aggressive or reactive dog meet with other dogs in the hopes that more exposure will help her feel better.
Your dog does need exposures to her trigger(s), but she needs calm, controlled exposures where we can manage the intensity of the trigger, duration of the exposure and the distance from the trigger so that she can learn how to successfully cope with future situations.
How We Can Help
We have transformed the behavior of our own leash aggressive dog and have helped hundreds of clients along this same journey.
In order to help your dog and make long-term behavior change we:
- Take a look at your WHOLE dog and not just the naughty behavior. We take a deep dive into your dog’s history and personality so you can understand WHY your dog is behaving this way. When you understand the WHY, you are in a much better position to know HOW to help your dog keep calm.
- Look at all the places your dog is displaying the leash aggression and behaving in an emotionally unregulated way so we can address all areas of problem behavior
- Teach the human end of the leash so you can avoid the big mistakes the owners of leash aggressive dogs often make
- Teach you and your dog the strategies and skills you need to counter the aggressive behavior so you can take a walk or have people over without feeling anxious
- Help you and your dog reclaim your happy, joyful life together where there is more fun and less stress for both of you.
The first thing to understand about leash aggression in dogs is that it is an issue of EMOTION. After helping hundreds of clients and their dogs with leash aggression and reactivity, we developed a training program that focuses on addressing the emotion first. Once your dog understands how to regulate her emotions in the presence of triggers, then we work on the strategies and behaviors you and your dog will need to stay cool, calm and collected anywhere and everywhere.
We know how stressful leash aggression can be and we want to help both you and your dog feel more confident, calm and in control. You can get started with a virtual or in-person Initial Consult. We look forward to meeting you!
