When we repeatedly prevent our dogs from reaching something they want (a desired stimulus) they can develop barrier reactivity. Frustration-based reactivity like this might look like barking, lunging, growling, and otherwise making a scene. Usually dogs show barrier aggression when confined in your yard or house. It might go hand-in-hand with leash reactivity on walks, too.
Sniffspot was designed with reactive dogs in mind. We know firsthand the struggle of working our pets through big feelings! In the below guide, we cover:
Most importantly? We equip you with practical insights to help your canine friend overcome their barrier frustration-related struggles. Let's get into it!
Frustration-based reactivity occurs when a dog wants to interact with something—a person, another dog, maybe even a specific object—but can't.
This behavioral problem is common in social dogs who regularly visit dog parks or attend daycare. These pups love other pets. It's natural they feel frustrated when they aren’t allowed to say hello! That frustration—especially when shut behind a barrier, like in a fenced yard, or held back on a leash—can quickly build into a reactive display. The outsized emotional response results in behaviors like growling and barking.
For the purpose of training your reactive dog, you can treat barrier reactivity and leash reactivity pretty interchangeably. Many pets who struggle with barking, lunging, and growling while on leash also have the same issues when behind a fence!
If we’re being technical, we can define leash reactivity as a type of barrier frustration, since a leash is a barrier. This article talks more about fixing leash reactivity, or leash aggression, specifically.
Dog trainers and pet parents might refer to a wide range of behaviors when they say "barrier aggression." Because of this, signs of barrier reactivity can vary. No two dogs will react in exactly the same way.
That said: You can look for some telltale symptoms of frustration-based reactivity. If your dog performs the below behaviors when confined behind a fence, gate, or on a leash, chances are they're struggling with barrier reactivity.
Your dog might show signs of anxiety, distress, or other negative emotional experiences by whining. It's common for our pets to whimper in a fenced yard or behind another barrier where they can't reach the things they want to.
Dogs may bark or growl when they see triggers like other animals, people, or environmental stimuli.
When your dog is restless, they might pace or jump up. Some dogs even try to completely clear the barrier in their way! This is a sure sign your pup is reacting to something on the other side.
Some dogs express their frustration by lunging, air snapping, or even attempting to bite their triggers. They can also redirect their frustration onto their handlers in particularly stressful situations.
Raised hackles, a tense body, and a fixed stare can be indicators of a heightened emotional state. Pay attention to your dog's body language to get a feel for their stress levels!
Wide pupils also suggest high arousal. It can be hard to get a good look at your pup's eyes when they're reacting to a trigger—but if you're able to see dilation? You know your dog feels some intense emotions. There's a good chance they're reacting strongly to a trigger.
Dozens of potential factors influence barrier and frustration-based reactivity in dogs. While some training protocols stay the same no matter the cause, understanding the roots of your own four-legged friend's explosions can help you more effectively manage your pup's behavior.
Dogs that haven't been adequately socialized to different environments, people, and animals may become reactive as a default when faced with unfamiliar stimuli. This frustration can be heightened when behind a barrier! Feeling trapped is a sure way to add frustration into the mix.
Dogs that haven't been trained to cope with frustration—or taught alternative behaviors when they feel overwhelmed—may resort to reactive responses when faced with barriers.
An important note here: If your dog is barrier reactive, it does not mean you haven’t done a good job with their training. It can be hard to teach our dogs to appropriately handle frustration! This is just one of many variables worth considering.
Certain breeds may have a genetic predisposition to reactive behaviors. Understanding breed characteristics—what jobs and traits our ancestors originally selected your dog for—can help you tailor your training approach to their specific needs.
Dogs are naturally territorial animals. This means it's normal for them to feel triggered when they perceive a threat to their territory! This protective behavior may lead to reactivity when they feel confined or restrained—especially on their own property when other people or animals pass by their home.
VCA Animal Hospitals says "Territorial aggressive displays may range from growling and barking to lunging, chasing, snapping and biting. ... Dogs that are physically prevented by a barricade or leash from gaining access to the stimulus (i.e., are frustrated) may have their aggression heightened, or may develop displacement behaviors (e.g., spinning, circling, self mutilation) or redirected behaviors (e.g., turning their aggression on the owner who attempts to reach for or grab the dog)."
Pain or discomfort due to underlying medical issues can contribute to reactivity. Veterinary examinations can help you rule out any health concerns.
Dogs that lack mental and physical stimulation may channel their excess energy into reactive behaviors. Regular exercise and mental enrichment are vital to keep your pup balanced, fulfilled, and well-behaved.
We promise we’ll get into the training itself soon, but first: Management is an important part of helping your barrier reactive dog. The more frequently your pet practices their unwanted behaviors in a heightened emotional state? The more deeply they ingrain those habits. You want to prevent as many reactions as possible so your training can be successful.
Don’t worry, though. You don’t have to be perfect. Your dog will still react to triggers. You can’t control the whole world—and no one expects you to!
Just a little bit of effort can go a long way to managing your dog’s behavior in the meantime.
Frustration-based dog reactivity and general overarousal can often be improved by simply addressing our pets’ underlying needs. As mentioned above, it’s possible that your dog is displaying reactive behaviors as signs of feeling ill, in pain, or unfulfilled!
You can increase your canine companion's exercise frequency and type. Be sure to include activities that let them move their body and use their brain in natural ways. Which brings us to...
How can you help your pet feel more fulfilled in our modern human world? Provide appropriate canine enrichment!
At its simplest, enrichment provides animals with opportunities to satisfy their innate instincts. Common enrichment activities usually give our dogs the chance to safely dig, sniff, and emulate their predatory sequence (searching, stalking, chasing, fighting, celebrating, and consuming) without causing harm to or disrupting the communities we live in. You might fill a rubber toy with peanut butter for them to lick out, focus on playing fun games together, set up structured playdates with dogs you trust, and more.
You can learn more about fulfilling your dog’s natural instincts in our comprehensive guide to canine enrichment. A bonus is that many of these activities can turn into alternate behaviors your dog performs around their triggers in the long run! You can also use them as part of a healthier behavior chain.
It’s always a good idea to evaluate your reactive dog’s basic needs before focusing on specific training situations. Even if your dog’s reactivity is driven by more than a treatable health or fulfillment problem, making sure their needs are met will still help you maximize your training success.
Once you've addressed any underlying issues, addressing your dog's barrier aggression often involves a combination of positive reinforcement training techniques like desensitization and counterconditioning.
Professional guidance from a certified force free dog trainer or behaviorist can be invaluable in developing a tailored behavior modification plan for your specific dog and situation!
Observation activities like engage-disengage and Look At That use counter-conditioning principles to help your dog feel a little calmer and think more clearly around their triggers. These games can be found in Leslie McDevitt’s Control Unleashed books!
Engage-disengage and Look At That methods capitalize on operant conditioning (a learning theory involving animals intentionally performing behavior to earn reinforcement) to create better responses (more agreeable behaviors like looking at you) than barking and lunging.
Desensitization involves getting our dogs used to their triggers slowly, in small doses that don’t put them over threshold. While it can be difficult to implement in the “real world” (public environments are often unpredictable and we can’t always decide how far away our dogs are from their triggers) it’s a valuable technique in controlled situations.
Distance, intensity and duration matter a lot in this behavior modification technique. The goal is to help your dog ultimately make a habit of calmer emotions, more relaxed behavior, and lower stress levels.

Does your dog ever growl when you walk by their food dish? Maybe they get possessive of treats, carrying them far away and giving you side-eye when you start to approach — or snarling at your other pets or children if they get too close.
As almost every dog owner is aware, the nose of a dog is an amazing thing. Just as they can pick up sounds we can’t hear, their sense of smell and ability to pick up scents is well beyond ours. In fact, dogs have 40 times the number of olfactory receptors as humans.
More than 80 million Americans rely on their service dogs to help them navigate the world.

Many dogs have gotten a bad reputation over the years for being "dangerous breeds." Rottweilers are among them. Like pit bulls and other large, blocky-headed types of dogs, these powerful and beautiful animals are often assumed to be aggressive.
Your dog is reactive. They’ll see another dog, person, or other stimulus in the environment (like a car or bike) while out on a walk and suddenly go crazy at the end of their leash. The barking, lunging, and growling feels embarrassing for you — and it’s clear that your pup isn’t having a great time either.
Does your dog display reactivity to other pets or people? Maybe they’re a new rescue pup and are still settling into your home. Or they were sick growing up, so you missed their critical socialization period. Possibly they’ve had a bad experience after being raised as a normal puppy.

From 2009 to 2020, there was a 40 percent increase in the development of public dog parks.

Thousand Oaks, California has been a safe haven for Sniffspot host, Jen, since childhood. Having grown up in busy Santa Barbara, Jen, an introvert from an early age, would seek out solitude and serenity away from tourists attractions and droves of people visiting from elsewhere. “My grandparents own 60 acres about a 30 minute drive from here, and I grew up spending every summer and every holiday visiting them on the ranch,” Jen explained. “In Santa Barbara, we wouldn't go to the beach on the weekend because that's where everybody was, so you'd find places off the beaten path where the tourists weren't. For me, the ranch was just my happy place.”
