Leash Reactivity
Leash reactivity is one of the most frustrating behaviour problems for dog owners. Your dog may be fine off-leash or at home — but the moment the leash goes on, they bark, lunge and pull at every dog, person or stimulus they see.
Why dogs react on leash
The leash fundamentally changes how a dog can respond to their environment. Off-leash, a dog has the option to approach, retreat or avoid. On-leash, those options are removed — and the dog is forced to confront stimuli at distances they may not be comfortable with.
This creates a perfect storm for reactivity. The dog can't escape, can't approach on their own terms, and often feels the tension of the handler through the leash. Over time, the dog learns that barking and lunging "works" — the scary thing moves away, or the handler turns around.
Leash reactivity is not a reflection of a "bad dog" or poor training. It is a predictable outcome of an emotional state (fear, frustration or over-arousal) combined with the physical constraint of the leash.
Common presentations
Understanding the motivation
Fear-based
The dog is trying to create distance. Barking and lunging are defensive — the goal is to make the threat go away. These dogs often show avoidance behaviours before the reaction.
Frustration-based
The dog wants to get to the stimulus but can't. Common in dogs who are social and friendly off-leash but become frantic when restrained. The leash itself becomes the source of frustration.
Over-arousal
The dog becomes so stimulated that they lose the ability to think clearly or respond to cues. The environment is simply too much for their current coping capacity.
How we help
Effective treatment of leash reactivity requires identifying the underlying motivation and working systematically to change the dog's emotional response to triggers. This is not about correcting the dog — it's about helping them feel differently about the things that trigger them.
Assessment
Identify triggers, thresholds, and whether the reactivity is fear-based, frustration-based or arousal-driven.
Management
Adjust walk routes, timing and equipment to reduce trigger exposure during treatment.
Sub-threshold work
Controlled exposure to triggers at distances where the dog can remain calm, gradually decreasing distance over time.
Handler skills
Teaching you how to read your dog's body language, manage distance, and respond effectively in real-world situations.
