How to Stop Your Dog Lunging at Other Dogs on Lead

Your dog spots another dog across the street. The lead goes tight, the barking starts, and you do what most owners do: grip harder and try to march past. Here is the hard truth. Pushing through is training the lunge in deeper.

Lunging on lead is one of the most common problems we see, and it is fixable. But not by force.

Why Does My Dog Lunge at Other Dogs on Lead?

Lunging is not your dog being naughty, dominant or stubborn. It is a reinforcement loop. A trigger appears, your dog reacts, and something rewards the reaction. Maybe the other dog moves away. Maybe the adrenaline spike itself feels good. Maybe your tension travels straight down the lead and confirms the threat was real.

Every repeat strengthens the habit. If you do not change what is reinforcing the behaviour, you will not change the behaviour.

Why Getting Closer Makes Lunging Worse

Once your dog is barking and throwing their weight into the lead, they are over threshold. The thinking part of the brain is offline. No treat, no command and no correction can land, because your dog cannot learn in that state.

Most owners try to fix lunging at exactly the point where fixing is impossible: two metres from the trigger. The real work happens further back, at a distance where your dog notices the other dog but can still hear you.

How the Turn Away Method Stops the Lunge

The fix is to interrupt the loop before it pays out.

Spot the trigger before your dog locks on. Ears forward, body stiff, eyes fixed: that is your cue, not the lunge itself.

Turn 180 degrees and walk the other way, calmly. No yelling, no yanking, just movement. Distance is your best training tool.

Re-engage where your dog can focus. Ask for their name or a sit. The moment they look at you instead of the other dog, mark it with a clear "yes" and reward.

Only close the distance when calm holds. If the lunge comes back, you went too close too soon. Reset further away.

Over time the picture changes. Seeing another dog stops meaning "explode" and starts meaning "check in with my owner".

What to Try Today

On today's walk, find your dog's distance. Spot a dog far enough away that yours notices but can still respond to their name. Mark, reward, then turn away while they are still calm. That is one clean rep, and clean reps are how the loop gets rewired.

One honest caveat: a blog post is a starting point, not a cure. If the lunging has been building for years, or there is any growling or snapping involved, you need experienced eyes on the dog. That is exactly what we do at Walkys Dog Training Academy, with 1:1 sessions and group programs built for real-world walking. Bring the dog. We will bring the plan.
