What 'Reactive' Actually Means (because it's not what most people think)

When I first heard someone describe Dottie as "reactive," I thought they were being polite.

What they really meant, I assumed, was that she was aggressive. Badly behaved. A problem dog. Turns out I was completely wrong. And honestly, I wish someone had explained what reactive actually means years earlier. Would've saved me a lot of stress and a fair bit of unnecessary guilt.

What reactive doesn't mean

Let's start with what reactive doesn't mean.

It doesn't mean your dog's aggressive. It doesn't mean they're dangerous. It doesn't mean they're badly trained or that you've done something wrong.

Reactive dogs aren't the ones quietly planning world domination. They're not the confident, pushy ones who'll barge up to anything without a care (although they sometimes like look it). Actually, it's often the opposite.

So what does reactive mean?

Reactive means your dog overreacts to triggers.

They see something - another dog, a person, a bike, a bin lorry, whatever their specific thing is, and they respond bigger than they need to.

Barking, lunging, spinning, pulling, going absolutely crackers on the lead. It looks scary. It sounds aggressive. But most of the time, it's not. Most of the time, it's fear.

Your dog sees something they're worried about and their brain goes straight to "MAKE IT GO AWAY." Barking and lunging is their way of creating distance. It's not "I want to attack that." It's "I need that thing to stay away from me."

Why do dogs become reactive?

Loads of reasons. And honestly, sometimes you'll never know.

Some dogs have had bad experiences. Another dog went for them when they were young. Someone scared them. Something traumatic happened and now they're on high alert.

Some dogs are just wired that way. They're sensitive. They find the world overwhelming. They're the canine equivalent of someone who needs to decompress after a busy day.

Some dogs missed out on socialisation when they were puppies. They didn't learn that other dogs are fine, so now every dog feels unpredictable and scary.

And some dogs? You genuinely have no idea. You did everything right and they're still reactive. That's just how they are.

With Dottie, I think it's a mix. She's always been sensitive, we got her in the first week of lockdown 2020 which didn't help. Add in a few dodgy encounters with other dogs when she was younger, and here we are.

What triggers look like

Every reactive dog has their own specific triggers.

For Dottie, it's quite a few different things. She doesn't like being confronted by a group of dogs. That's her absolute nightmare scenario. Followed by people who move a bit weirdly, big hats, pull a long cases. She doesn't like the sound of tyres when the road is wet. I could go on.

For other dogs I've come across - it can be:-

• Bikes or runners (anything moving fast)

• People in hats or carrying umbrellas

• Skateboards (the noise sets them off)

• Other dogs but only specific types (usually big dogs, or small yappy ones)

• Men with beards (weirdly specific but I've seen this a few times)

• Bin lorries, delivery vans, anything loud

The trigger can be anything. And sometimes it's multiple things. Lucky you if your dog's only got one.

The threshold thing

Here's something I didn't understand for ages: distance matters.

Dottie can see a dog 50 meters away and be fine. A bit tense, but manageable.

Same dog at 20 meters? She's barking, lunging, absolutely losing it.

That's threshold. The point where your dog tips from "I can cope with this" to "I CANNOT COPE WITH THIS."

Every reactive dog has a threshold. And it changes depending on the day, how full their stress bucket is, how the other dog's behaving, whether you're on a familiar route or somewhere new.

Learning your dog's threshold is massive. Because if you can keep them under it - far enough away that they're noticing the trigger but not losing their mind - that's where progress happens.

Reactive doesn't mean aggressive

This is the bit that really matters.

Reactive dogs usually aren't trying to hurt anything. They're trying to protect themselves.

If a reactive dog actually got into a fight, most of them would panic. They're not confident fighters. They're anxious dogs who've learned that making a big noise creates space.

Obviously, there are exceptions. Some dogs are genuinely aggressive. But genuinely aggressive dogs are way rarer than reactive ones.

Most of the time, when your dog's kicking off on the lead, they're scared. Not dangerous.

Why "just socialise them more" doesn't work

People love to tell you this.

"Your dog just needs to meet more dogs." "They'll calm down once they realise other dogs are fine." "You're being overprotective."

Here's the thing: forcing a reactive dog into situations that scare them doesn't fix them. It makes them worse.

Every time your dog goes over threshold - every time they have a massive reaction - it reinforces the idea that other dogs (or whatever their trigger is) are terrifying. You're not desensitising them.

What actually helps is controlled exposure. Keeping them under threshold. Letting them see the trigger from a distance where they can cope. Pairing it with good things (treats, praise, whatever your dog loves). Building positive associations slowly.

But that takes time. And space. And understanding that your dog's not going to be magically "cured" after three walks. This approach worked really well for Dottie with cars as she used to launch at one every time they passed. But with patience, things have improved significantly but it took months and months.

Living with a reactive dog

I'm not going to lie, it's hard sometimes.

You can't just open the door and go for a walk. You have to plan routes. You have to scan ahead constantly. You cross the road five times in ten minutes.

You get judgmental looks from people who don't understand. You get comments like "you need to train your dog" or "my dog would never behave like that." And often you feel guilty. Like you've failed them somehow.

But here's what I've learned: reactive dogs are often brilliant dogs. They're sensitive, intelligent, loyal. They're just wired differently.

Dottie's reactive. She's also the most loving, funny, crazy, ridiculous and intelligent dog I've ever had. Her reactivity doesn't define her. It's just something we manage.

What this means for walks

When I walk reactive dogs, I get it. I've lived it.

I know what it looks like when a dog's about to kick off. I know how to create space. I know which routes are quiet and which ones are going to be stressful.

I know that some dogs need to see another dog and immediately turn around. I know that some dogs are fine if the other dog's on-lead but panic if they're loose and vice versa.

And I know that reactive doesn't mean badly behaved. It means your dog needs things a certain way.

The bottom line

If someone tells you your dog's reactive, they're not insulting your dog. They're describing a behaviour pattern. If your dog's reactive, it doesn't mean there's something wrong with them. It means they find certain things harder than other dogs do.

That's it. That's all it means.

If you've got a reactive dog and you're tired of people not getting it, I get it. Been there. Still there, actually. I also appreciate it can be really draining walking your dog every day and sometimes it's a relief to let someone else take the lead.

One-to-one walks. Quiet routes. Space from other dogs. Understanding that reactive doesn't mean badly behaved. If that sounds like what your dog needs, drop me a message. Let's chat.
