The Difference Between Fear-Based and Excitement-Based Reactivity

If you’ve ever had a dog lose it on leash, you know how similar it can all look.

Barking. Lunging. Pulling. Completely checked out.

From the outside, it’s easy to label all of that as “reactive” and leave it at that.

But what’s driving it underneath matters a lot more than what it looks like.

Most of the time, it falls into one of two categories.

The dog is trying to get away… or the dog is trying to get to something.

Fear-based reactivity is about creating distance.

The dog is uncomfortable, unsure, or overwhelmed, and the reaction is their way of saying “I need this to go away.”

These are the dogs that might freeze for a second, stare, then escalate.

Or they try to move away but can’t because of the leash, so it builds into barking or lunging.

You’ll often notice their body looks tight.

There’s hesitation in there somewhere, even if it turns into a big reaction quickly.

Excitement-based reactivity is almost the opposite.

The dog isn’t trying to get away… they’re trying to get access.

They see another dog or person and go straight into a high level of arousal they can’t control.

So they pull, vocalize, and lose focus because they want to get there and don’t know how to regulate that feeling.

These dogs usually look more forward, loose, sometimes even “happy”… but still completely out of control.

Here’s where people get stuck.

They treat both the same.

Either they assume the dog is scared and go overly soft with a dog that actually needs more structure…

Or they assume the dog is just “friendly” and keep putting them into situations they can’t handle yet.

And both slow things down.

A fear-based dog usually needs:

  • More space

  • Slower exposure

  • Clear ways to disengage and feel safe

An excitement-based dog usually needs:

  • More boundaries around access

  • Better impulse control

  • More structure in how they move through the environment

And a lot of dogs sit somewhere in the middle.

They might start excited, then tip into frustration, then into stress.

So it’s not always perfectly one or the other.

The key is asking a simple question.

Is my dog trying to create space… or close the gap?

Once you can answer that, your training decisions get a lot more clean.
