Do Harnesses Cause Dogs to Pull?

It’s one of the most common things I hear from dog guardians: “I’ve been told not to use a harness because it makes my dog pull.” It’s a simple idea, but it’s also misleading.

Harnesses do not inherently cause pulling. Dogs don’t pull because of what they’re wearing; they pull because of what they’re feeling, experiencing and learning.

Pulling on the lead is usually a symptom, not the root problem. For some dogs, it’s excitement; the world is fast, stimulating, and full of things they want to get to quickly. For others, it can be anxiety or fear, where pulling is actually an attempt to create distance from something overwhelming. Frustration is another big one, especially in dogs who can see other dogs, people, or wildlife but can’t access them. Then there are dogs dealing with underlying physical discomfort, such as joint or muscular pain, where movement patterns and tension can change how they walk entirely. And of course, there are dogs who have simply learned over time that pulling works, because it gets them where they want to go.

A harness doesn’t create any of these motivations. What it does do is avoid adding pain or discomfort into the situation. This is often why people feel like their dog “pulls more” in a harness, because the behaviour isn’t being suppressed. If you switch to equipment that relies on pressure or discomfort, you may see less pulling, but that doesn’t mean your dog has learned to walk calmly. It usually means they’re avoiding the sensation. That’s not the same as understanding how to move with you on a loose lead.

Another important piece that often gets overlooked is that not all harnesses are created equal. Some designs can restrict shoulder movement, sit too close to the armpits, or apply pressure in ways that affect your dog’s natural gait. Over time, this can lead to discomfort or compensatory movement patterns, which can feed back into behaviour. Choosing an anatomically appropriate harness matters far more than whether you use one at all. If you’re unsure what to look for, I’ve put together a free guide to help you choose a harness that supports your dog’s movement rather than interfering with it.

There’s also a common belief that harnesses give you less control. But if control comes from equipment, rather than from your dog choosing to engage with you, then the issue isn’t the harness, it’s the training. A dog who can walk calmly on a loose lead is not being physically controlled; they are regulated, connected and responding to clear, consistent guidance. Equipment doesn’t teach that. It can only either allow it or suppress behaviour around it.

Harnesses are widely considered the most humane and ethical option for dogs who pull because they avoid placing pressure on sensitive areas like the neck and throat. Many alternative tools rely, to some extent, on discomfort or pain to reduce pulling. While they may change what the behaviour looks like on the surface, they don’t address the emotional or physical reasons behind it. And without addressing those underlying causes, the behaviour tends to persist or show up in other ways. Not to mention making your dog feel pretty awful inside.

If you genuinely want to stop your dog from pulling, the answer isn’t changing the tool, it’s understanding the dog. That means looking at why they’re pulling in the first place, supporting their emotional state, and teaching them what calm, loose lead walking actually looks like in a way they can understand and succeed with. When that’s in place, the equipment becomes far less relevant.

If you’re struggling with lead pulling and want tailored support, I offer 1:1 dog training and behaviour support both online and in Berkshire, focusing on ethical methods that get to the root of the issue. You can also access my Calm Lead Walking module inside the Whole Dog Hub, where I break this down step by step and guide you through exactly how to build loose lead walking in a way that actually lasts.
