Understanding Your Dog’s Reactivity

Looking Beyond the Bark

Have you ever been out walking when your dog suddenly starts barking, lunging or reacting to something in the distance?

It can feel stressful, embarrassing and sometimes even frightening.

But reactivity doesn't mean your dog is "bad."

More often than not, it means they're struggling to cope with something in that moment.

Reactivity is usually driven by strong emotions such as fear, anxiety, frustration, excitement or feeling overwhelmed. Sometimes pain or underlying health conditions can also make dogs more sensitive to the world around them.

The behaviour you see is often your dog's way of saying,

"I'm finding this difficult."

What Is a Trigger?

A trigger is anything that causes your dog's emotional response.

Every dog has different triggers, and they don't always stay the same.

Common examples include:

✓ Other dogs

✓ People

✓ Children

✓ Cyclists or runners

✓ Wildlife

✓ Traffic

✓ Loud noises

✓ Weather

Sometimes the trigger isn't obvious at all.

A dog may react only to large dogs, only when another dog is running, or only when they are on lead.

Distance, environment and previous experiences all play a part aswell

Trigger Stacking

Dogs don't experience each event in isolation.

Stress can build throughout the day.

This is known as trigger stacking.

Imagine your dog has:

• Heard fireworks the night before.

• Had a stressful trip to the vet.

• Been startled by a barking dog.

• Then encounters another dog on a narrow path.

Each event adds a little more stress until your dog simply can't cope anymore.

Sometimes the reaction you see isn't caused by one trigger—it can be the result of everything that happened beforehand.

Behaviour is communication

Behaviour and health are closely connected.

Pain, illness or discomfort can reduce a dog's ability to cope with situations they would normally manage well.

If your dog's behaviour suddenly changes or their reactivity becomes worse, it's always worth speaking to your vet.

Keep a Trigger Diary

One of the most useful things you can do is start noticing patterns.

Try making a note of:

🐾 Your dog's body language

🐾 What happened before the reaction

🐾 Where you were

🐾 Distance from the trigger

🐾 Your dog's response

🐾 Any health changes

Over time you'll begin to notice patterns that help you better understand your dog's behaviour.

Understanding Comes Before Change

Rather than asking,

"How do I stop this behaviour?"

Try asking,

"Why is my dog behaving this way?" (What is he/she trying to say)

The answer is often much more valuable.

When we understand our dogs, we can adapt the environment, reduce stress and support them in ways that build confidence instead of simply trying to suppress behaviour.

Our aim isn't to "fix" dogs—it's to understand them. Through calm routines, enrichment, gradual experiences and meeting each dog's individual needs, we help dogs feel safer, more confident and better able to navigate the world around them.

Because your dog isn't giving you a hard time.

They're having a hard time.
