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.
Whatever the case: Don’t worry. Reactivity is one of the most common dog behavior concerns—and you can help your adult dog feel better about social situations in the world around them. Positive interactions go a long way!
Let’s dive into socialization specifics for dogs who display reactive behaviors like barking, growling, and lunging at specific triggers. (You can read more about training through leash reactivity itself in this blog.) We cover:
(Looking for a checklist for puppy socialization instead? We've got you covered in this other article!)
First, let’s get our definitions straight. Dog reactivity is a big term!
While every living animal is constantly “reacting” to its environment—you might put on a sweatshirt when you notice you’re cold or head to open the door when you hear a knock—“reactive” is used in the dog training world to describe pets who overreact to stimuli in their environments. Reactivity generally encompasses a range of unwanted behaviors (barking, growling, lunging, jumping, pulling) in situations that typically don’t warrant them (when triggers are behaving normally in a non threatening way).
Basically: Your dog who woofs once or twice when startled? They wouldn’t be diagnosed with reactivity. One who barks, growls, and lunges at every other dog they see out on a walk, on the other hand? They would be considered reactive.
Some reactivity can actually be improved by simply addressing our pets’ underlying needs. It’s possible that your dog is displaying reactive behaviors because they’re feeling ill, in pain, or unfulfilled. Other reactivity is more deeply rooted in fear or frustration and will take more than veterinary care and enrichment to work through.
Regardless: It’s always a good idea to evaluate your reactive dog’s basic needs before starting a training or socialization process!
Canines are great at hiding discomfort. If your dog is reacting when being touched by people or playing with other dogs—especially if they’re suddenly sensitive in situations they used to tolerate well—there’s a good chance they’re in pain. Pay attention to their subtle body language signals (especially signs of stress, like lip licking or excess yawning).
A thorough vet check should help you identify any problems. Even the most careful socialization plan won’t help your reactive dog if their behavior is the result of an injury or illness.
We bred certain traits into dog breeds over generations and generations. Two examples: Herders are hyper-aware of their surroundings, and terriers have an intense desire to chase prey. So if your cattle dog is barking at quick-moving objects or your jack russell keeps lunging after rabbits, there’s a chance their reactivity is caused by unmet genetic instincts rather than a lack of socialization.
How can you help them feel more fulfilled, if that’s the case? 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.
If your dog is still reactive after you’ve met their basic health and fulfillment needs, spend some time thinking about why they bark, growl, and lunge at certain things.
Typically, reactive dogs have one of two goals in mind. They either want to get away from something scary (this is fear-based reactivity) or want to get closer to something exciting (this is frustration-based reactivity).
Fear-based dog reactivity is often caused when nervous or uncertain dogs feel trapped in a certain situation. Think about a porcupine puffing out their quills to make something scary go away! Your dog might appear aggressive—but they don’t want to go out of their way to cause harm. They’re just experiencing anxiety and really want to be left alone.
You can read more about fear aggression in this guide.
Frustration-based leash reactivity, on the other hand, stems from a dog wanting to interact with something they can’t. This is common in social dogs who regularly visit dog parks or attend doggie daycare. They love other pets and get frustrated when they aren’t allowed to greet them! That frustration (especially when being held back on a leash) can quickly build into a reactive display.
Regardless of the cause of your dog’s reactivity, it’s important to keep safety top of mind while you socialize them. Even merely scared or friendly dogs can still cause harm when pushed too far.
Above all: Don’t be afraid to manage your dog’s environment to set them up for success. If you see a trigger up ahead on a walk? There’s no shame in turning around to avoid it if you aren’t prepared to work your dog through it on that given day! If you get invited to a friend’s BBQ with other people and pets? Maybe it’s best to leave your reactive dog at home until you’ve been able to work through less chaotic situations.
Take a look at some more specific types of management below. By following these protocols, you'll be able to achieve a higher level of socialization with your dog—while avoiding unnecessarily stressful situations.
If you think your dog might be a bite risk—or if you just appreciate a visual cue that they don’t want to be approached—it’s a good idea to train them to wear a muzzle. When properly sized and conditioned, muzzles don’t cause any discomfort. Instead, they give your dog more opportunities to enjoy the world! You can read more about muzzle training your reactive dog in this article. The key is to create a positive association with their new “party hat” by using lots of treats and moving slowly.
You might also consider some other tools to help strangers know your dog needs space. There are a wide variety of special collars, leash wraps, and harness patches that say things like:
Along with using available tools to get space and keep your dog safe, it’s a good idea to visit new environments at less-busy times. Your reactive dog absolutely needs exposure to the world around them—but that exposure needs to be through slow, supported experiences that don't make them feel overwhelmed.
Consider walking early in the morning or visiting public squares at off times. And when you go somewhere…
Imagine potential scenarios and consider how you’ll respond to them when you’re socializing your dog. If one path gets blocked by a trigger, do you have another way out? How far away will you be from your car? Don’t let yourself spiral into unproductivity—we can’t plan for every last contingency in our messy modern world—but do spend some time preparing for likely events.
When your dog is a new puppy, you might feel pressured to socialize them quickly. Puppies have a critical period of socialization window between about three and fourteen weeks of age. The more exposure they get to the world around them in that time period? The better off they'll be!
Once your dog is an adult, though, the time frame for socialization shifts. They've missed out on some key aspects of puppyhood socialization—but they can still reap later benefits of socialization including increased confidence and a greater ability to relax. As long as you're patient, that is!
Socializing your reactive dog is a marathon, not a sprint. You want to create lasting, long-term results! While it’s tempting to rush the process, sustainable behavior change comes from addressing your dog’s underlying emotions.
As a rule of thumb: It’s better to have just a few good experiences than to have several good and one bad. This is especially true if your dog’s reactivity is fear based! In order to help our canine companions heal, we have to make sure we don’t push them too far too soon.
There are no quick fixes here—no set number of days of socialization before your reactive dog is better able to stay calm. That's okay! Try not to compare yourself to others. And always let your own dog show you how they're feeling.
The best way to ensure you can move at your dog’s pace? Plan opportunities for socialization with other people and dogs you trust. This way you can be in control of the entire set up, which:
A professional trainer can be a fantastic resource for this. Many of them have their own helper dogs they can bring along to training sessions—and they also tend to have a good gauge on surrounding park, trail, and business environments so you know what to expect going in.
If your dog has a bite history, it’s especially important to work with a positive reinforcement expert to keep everyone safe.
As mentioned above, not all dog reactivity is the same. It’s important to pay attention to the function of the behavior when making socialization decisions. Are our dogs barking to create space from something? Are they actually wanting to get closer to the thing they’re reacting to?
Below we share a brief breakdown of socialization training depending on the cause of your dog’s reactivity.
If your dog is afraid of other dogs or people in their space, it’s important to show them you have their back. They don’t need to be wary of every other animal they see. You’ll protect their space!
You can advocate for your dog in many ways:
You might not understand why your dog is afraid, but to them? Their triggers are the scariest things in the world. Never force your dog to interact with something that’s making them uncomfortable.
Instead, prioritize pleasant exposure more than direct interaction. This is often called passive socialization. Your dog is still learning even if they aren’t right next to their triggers! Make your sessions a positive experience your dog can feel confident about.
One great way to build confidence through careful exposure is parallel or “blended” walks where you allow your dog to investigate their trigger from a comfortable distance and only help them out when needed. This way they’re below threshold—their brains are able to process information!
If your dog displays unwanted behaviors, evaluate what went wrong. Did they get surprised? Are you too close to the trigger? Then take a break before trying again. You can use techniques like food scatters to bring their arousal back down.
When in doubt, help your dog out by redirecting their attention or moving farther away from their triggers. Starting slowly is better than not starting at all.
Many of the same protocols apply to both fearful dogs and excited greeters. We should build trust, practice being calm around triggers, take things slowly, and generously reward their effort and good behavior.
One exception, though? While a fearful dog should never be pushed to interact with another animal, a pet who is fundamentally social but simply over aroused (like from being restrained on a leash when wanting to say hello to another dog on a walk) can actually benefit from regular opportunities to play with canine friends.
This goes back to our above section on meeting our dog’s needs. Think about a dog who has a very high prey drive. When we give them safe opportunities to express their instincts—like through chasing a flirt pole or entering a local barn hunt class—they feel more fulfilled. That sense of satisfaction then makes it easier for them to ignore other critters like rabbits and squirrels while out and about! The same applies to reactive dogs who just can’t believe the entire world doesn’t want to say hi to them.
As a bonus: We’re able to manage our dogs’ behavior in these controlled situations to build healthier emotional regulation habits in the long run. We don’t want to teach our pets that they’ll get to interact with every dog they see—that can make their reactivity worse—but we do want to meet their needs in safe, appropriate ways.
If your pet enjoys playing with other dogs but struggles with excitement, arousal, or general social skills in traditional dog park settings, a private Sniffspot can be the perfect place for controlled playdates or sessions with your professional trainer. These off-leash areas enable you to meet up with trusted friends and take interactions as slowly as you need to so safety is always the top priority. No worrying about running into strange people or dogs!
Working with dog reactivity can be a messy process. Sometimes it’s hard to understand exactly where your dog’s reactions are coming from. Are they scared? Excited? Maybe a little bit of both? Not to mention the many ways to approach their behavior—and how nerve wracking it can be to find a trainer you trust.
You’re not in it alone, though. There’s an amazing community of reactive dog owners working to give their pets the best care possible. (And good news: even fearful or unsocialized dogs can have incredibly full, happy lives.)
We should aim to both accept our dogs for who they are and pursue ways—like appropriate socialization and tailored enrichment plans—to help them navigate daily life in our modern world.

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. Task-trained assistance animals perform a huge range of life-changing—in many cases, life-saving—services: These dogs act as eyes for visually impaired handlers, provide mobility support, alert to seizures and blood sugar crashes, interrupt anxiety attacks, remind their people to take medications, and so much more.
You thought your dog was house trained. Your home was clean from puddles of pee, those dreaded middle-of-the-night bathroom breaks were behind you, and you loved every minute of dog ownership… until your four-legged best friend started using the bathroom inside again. What’s going on?
Ah, poop. We humans think it’s disgusting… but many of our dogs seem to love the stuff. If you’re wondering why your canine companion tries to eat feces (either their own or that of other animals) you’re not alone!
Do you have a water-loving dog looking to burn some energy? There are countless dog parks to visit throughout our country — but some of them become far too hot in the midday sun to be safe for your pets to play. That’s why we’ve put together a list of some of the best dog water parks throughout the United States! At these locations, your pup can frolic, splash, and swim to their heart’s content.

Does your dog destroy every toy you give them? Is your house littered with remnants of fabric and stuffing of all different sizes? Are you tired of investing in “indestructible” toys only for your pup to still dismantle—or worse, get bored of—them in just a few days?
You’ve been told your dog needs regular exercise. There’s a reason “walking the dog” is a classic daily activity: Frequent excursions give your pup a chance to experience the world, maintain a healthy weight, and — most importantly — spend time with you! Consistent physical activity can also improve their strength, muscle tone, coordination, and mental ability over time.

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. Designated spots for canine exercise have become commonplace in every major city in North America — many pet owners won’t even consider renting an apartment that doesn’t have its own fenced-in pet area for their canine companions.
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.”
