🤔Imagine being frightened of something.
🤔Now imagine that every time you encounter that frightening thing, someone causes you pain or discomfort.
🤔Would you become less frightened?
Or would you become even more anxious, more vigilant, and more desperate to avoid it?
💯This is exactly what we risk doing to reactive dogs when we use equipment designed to control behaviour through pain, pressure, discomfort or fear.
I’m talking about:
❌ Prong collars
❌ Choke chains
❌ Electric/shock collars
❌ Slip leads used to tighten around the neck
❌ Head halters (such as Haltis) that can cause discomfort or exert pressure on the dog’s head and neck
👀Let’s look at this from the dog’s perspective.
🐶Imagine you have a dog who is frightened of other dogs.
When another dog appears, your dog barks, lunges, growls or pulls towards them.
Why?
➡️Because, for many fearful reactive dogs, these behaviours are attempts to make the perceived threat GO AWAY.
➡️Your dog isn’t being naughty. They’re not trying to dominate you. They’re not deliberately giving you a difficult time.
⚠️They’re having a difficult time themselves.
Now, let’s introduce an aversive piece of equipment.
SCENARIO 1: WITHOUT ADDED PAIN
🐕 Another dog appears.
➡️ Your dog feels worried or threatened.
➡️ Your dog barks and lunges, trying to increase the distance between themselves and the perceived threat.
The dog is already experiencing a negative emotional response.
SCENARIO 2: WITH AVERSIVE EQUIPMENT
🐕 Another dog appears.
➡️ Your dog feels worried or threatened.
➡️ Your dog barks, lunges or pulls.
➡️ The prong collar tightens, the choke chain constricts, the slip lead applies pressure, the head halter twists or restrains their head, or an electric collar delivers a shock.
➡️ Your dog now experiences PAIN OR DISCOMFORT ON TOP OF THEIR EXISTING FEAR.
And here’s where things can become considerably worse.
✅YOUR DOG STARTS MAKING ASSOCIATIONS.
Dogs learn through associations.
⚠️If the appearance of another dog repeatedly predicts pain, discomfort or frightening experiences, your dog may begin to associate other dogs with those unpleasant consequences.
Think about that for a moment.
🤨Your dog was ALREADY worried about other dogs.
🤨Now, other dogs may also predict something physically unpleasant happening to them.
🤨So what happens the next time a dog appears?
➡️Your dog may become worried sooner.
➡️They may react at a greater distance.
➡️They may bark louder, lunge harder or become more desperate to escape or drive the other dog away.
➡️Because now they’re not just anticipating the dog.
➡️They’re potentially anticipating the pain or discomfort that has repeatedly accompanied the dog’s appearance.
😨And so we create a vicious cycle.
🔄 Dog appears.
🔄 Anxiety increases.
🔄 Dog reacts.
🔄 Pain or discomfort follows.
🔄 Negative associations become stronger.
🔄 Dog becomes increasingly worried about the next encounter.
And round and round we go.

A dog who repeatedly experiences frightening or unpleasant encounters may begin to change how they navigate the world.
⚠️ Increased hypervigilance.
Constantly scanning the environment, looking for other dogs, unable to relax and enjoy their walks.
⚠️ Increased sensitivity to triggers.
Reacting to dogs at greater distances, or to things they previously tolerated.
⚠️ Trigger stacking.
Repeated stressful encounters without sufficient recovery can leave the dog increasingly sensitive and less able to cope with subsequent triggers.
⚠️ Anticipatory anxiety.
Becoming worried before another dog even appears, because certain locations, situations or routines now predict unpleasant experiences.
⚠️ Elevated stress levels.
Repeated stressful experiences contribute to prolonged stress, affecting sleep, recovery, behaviour and overall welfare.
⚠️ Potential physical consequences.
Pressure on sensitive areas, including the neck, can cause discomfort or injury. Prolonged / chronic stress also affects physical health.

🙁Sometimes, aversive equipment appears to work.
The dog stops barking.
Stops lunging.
Stops growling.
And the owner thinks:
“Brilliant! We’ve fixed the reactivity!”
BUT HAVE YOU?
🙁Or have you simply taught your dog that expressing their discomfort results in something even more unpleasant happening?
💯A dog who stops reacting outwardly isn’t necessarily a dog who feels safer.
💯SUPPRESSION OF BEHAVIOUR IS NOT THE SAME AS CHANGING THE EMOTION BEHIND IT.
💯A quiet dog can still be a terrified dog.
💯And when we suppress the warning signals without addressing the underlying fear, we risk leaving the dog with fewer ways to communicate their distress.
💁🏼SO WHAT SHOULD WE BE DOING INSTEAD?
🩵We should be working towards changing how the dog FEELS about their triggers.
❤️ Use comfortable, properly fitted equipment that allows natural movement and doesn’t rely on pain or intimidation.
❤️ Create enough distance from triggers for the dog to feel safe and remain able to learn.
❤️ Use carefully planned desensitisation and counterconditioning to build more positive associations.
❤️ Teach alternative behaviours through positive reinforcement, rather than punishing fear-driven responses.
❤️ Consider pain, medical conditions and other factors that may be contributing to the dog’s behaviour.
❤️ Allow sufficient recovery time between stressful experiences.
❤️ Give dogs choice, predictability and opportunities to feel safe.
🩵Because the goal of reactivity training should NEVER be simply to make the barking and lunging disappear.
🩵The goal should be to help the dog feel safe enough that they no longer NEED to respond that way.
And here’s the question I’d like every reactive dog owner to consider:
🙌If your dog is already frightened of something, why would we want to make that experience even more unpleasant?
🙌Your dog doesn’t need more reasons to fear the world.
🙌They need your help learning that the world can be safe.
✅And that starts with the choices WE make on their behalf.
