I’ve been coaching professional dog trainers for over fifteen years, and if there’s one behavior issue that shows up again and again, in every corner of the country, at every skill level: leash reactivity. It’s one of the most common reasons dog owners go looking for professional help, which means it’s also one of the most common ways trainers build (or fail to build) a reputation.
Think about what it means to be known as the trainer in your area who gets results with reactive dogs. It can lead to an evergreen flow of referrals: from happy clients, from other trainers who don’t want these cases, from vets, daycares, groomers – anyone who deals with a stressed-out dog and a frustrated owner and doesn’t know where else to send them. Leash reactivity is a problem for dogs and owners, but for us trainers it can be an opportunity. Handling it well is good not only for business, but for your confidence as well.
Over the next few posts, I want to walk through the mistakes I see most often, not because I think I’m the last word on reactivity, but because after watching hundreds of trainers work these cases, some patterns repeat themselves constantly and they hold a lot of trainers back from reaching their full potential.
A quick note before we start: not every trainer makes every mistake on this list. Some make all of them. Some make none. Most make one or two. If you read through this series and find that a particular mistake doesn’t apply to you, good, let it be a confidence check, and a reminder that you’re already doing this part right. And if you do see yourself in one of these posts, I’d just ask that you read it with some openness rather than defensiveness. That’s the whole point of writing it.
Mistake #1: Changing How The Dog Feels…
Leash reactivity can have a few different root causes, but by far the most common one is some form of insecurity/fear/uncertainty. Whatever label you want to put on it, the dog doesn’t feel safe.
The first mistake I want to talk about is really a category of two closely related mistakes, both having to do with how trainers try to resolve that underlying insecurity.
The first problem: many trainers operate under the assumption that counter-conditioning and desensitization are the only tools available for changing how a dog feels around a trigger.
The second problem: many trainers only think about changing how the dog feels around the trigger in general, but as you’ll see this isn’t the full story.
Let me start with this second one, because it’s a bit more nuanced and once you understand it, you will see how it relates to the first.
I’m scared, but not when I’m with you…
When my kids were young, they were both afraid of the basement. Neither of them would go down there alone. Not with each other, not with a friend. But if my wife or I went down with them, the fear disappeared.
Their opinion of the basement never changed. It was still, in their minds, a place with something to be afraid of. What changed was how they felt about the basement when they weren’t alone with it.
That distinction matters enormously in reactivity work. There’s a real difference between:
- Helping a dog feel safe around other dogs in general, and
- Helping a dog feel safe around other dogs when they’re with their owner.
The second one isn’t just easier and faster to build when it’s done properly, it also feeds directly into the first. Change how a dog feels with their handler present, and you’ll have much more leverage and opportunity to change how they feel about the trigger overall, too. It’s often the faster path to the very thing counter-conditioning is trying to achieve.
Back to Counter-Conditioning
This is where the two problems intersect. The assumption that counter-conditioning and desensitization are the only way to shift a dog’s emotional state doesn’t just limit how we think about changing feelings around the trigger, it limits how we think about our entire training plan.
I want to be clear: I’m not discrediting counter-conditioning. It’s a legitimate, valuable piece of the puzzle. But if we treat it as the only lever we have, we miss out on some of the most powerful tools available for rehabilitating a reactive dog.
Showing a dog, through your own behavior, that you see the danger and know how to handle it can shift how that dog feels around the trigger with you far faster than counter-conditioning can shift how it feels about the trigger in general. Fewer repetitions. Faster buy-in. And it doesn’t require the trigger to be perfectly staged at the right distance and intensity, the way good counter-conditioning does.
This can look like a lot of things: navigating the environment to efficiently gain space before the dog escalates, or stepping forward and running interference when a trigger does get close, showing the dog that you’ll handle it, so they don’t have to. I’m not going to get into the mechanics of how here, those are the types of things the trainers I coach learn in detail, but these skills are genuinely learnable, easy to set up in controlled exercises, and they’re not complicated once you see them.
Counter-conditioning says: “You should feel differently about this thing.”
What I want to establish first says: “It’s okay to feel how you feel about this thing. But when you feel that way, you can trust me. Here’s how we, as a team, deal with it.”
One tries to convince the dog that the “danger” isn’t real. The other demonstrates to the dog that when there is danger, they can count on you.
Why I Start Here
I could give you a dozen reasons I lead with this before layering in counter-conditioning, but the biggest one is this: no matter how good your counter-conditioning protocol is, your dog will eventually run into something new. Some novel situation, trigger you never trained for, or scenario you didn’t anticipate. You cannot counter-condition your way to covering every variable life will throw at your dog.
But if you’ve already established that you’re competent, that you notice danger and know how to handle it, you’ve insulated your dog (and yourself) from all of that unpredictability. You’ve built something that generalizes, rather than something that only holds up in rehearsed scenarios. When it comes to our clients we’ve not only taken huge steps towards resolving this problem but we’ve actually taken steps toward resolving or avoiding future problems that haven’t even come up yet.
There’s a passage from Konrad Lorenz’s On Aggression that I think about often. He describes a mother hen out in a field with her chicks. The chicks are fat, happy, and relaxed. Their heads are down in the tall grass, absorbed in foraging. The mother is scrawny by comparison. Her head stays up. She’s scanning for predators the whole time.
That’s what we’re trying to build with our dogs. We want them relaxed on the walk. Sniffing. Present in their environment instead of scanning it for threats. We want them to trust that we’re the one with our head up, watching for the things they find dangerous, and that we have a plan for handling those things so they don’t have to carry that weight themselves.
Where Counter-Conditioning and Socialization Still Fit
None of this means counter-conditioning gets thrown out. It absolutely belongs in a long-term plan. So does socialization, when it’s appropriate. It’s one of the most organic and powerful ways to shift how a dog feels about a trigger in general, over time.
But relying on counter-conditioning alone, without ever establishing that the dog can trust your read on a situation and your ability to handle it, is a missed opportunity. It’s slower, it’s more fragile, and it leaves out one of the fastest, most durable tools we have.
That’s mistake number one. Next post, we’ll get into mistake #2: The Obedience Trap.
