Short answer
Dogs pull because pulling gets them where they want to go, so it is continually rewarded. The fix is to stop moving forward whenever the leash goes tight, applied consistently on every walk.

It is not dominance and it is not stubbornness. Your dog pulls because pulling works. Every time the leash goes tight and you keep walking, you have just paid for pulling.
Dogs also simply walk faster than we do. A comfortable human pace is slow for most dogs, and the world smells interesting in a direction that is usually ahead of you. Pulling is the obvious solution to a genuine mismatch.
The opposition reflex, and why pulling back fails
There is a second mechanism worth knowing about. Dogs — like people — have an opposition reflex: an automatic tendency to push against steady pressure. Lean on someone and they lean back without deciding to.
This is why hauling on the lead makes pulling worse rather than better. You apply backward pressure, the dog reflexively resists forward, you apply more, and you have built a tug-of-war against an animal with four-wheel drive and a lower centre of gravity. Steady tension is the one thing guaranteed to sustain the behaviour.
The method
- Stop the instant the leash tightens. Not a correction, not a word. Just stop, and let the lead go slack in your hands rather than bracing against it.
- Wait. Your dog will eventually ease the tension or look back at you. Say nothing while you wait.
- Walk on the moment the leash slackens. Moving forward is the reward, and it now only ever follows a loose lead.
- Repeat. Your first few walks will be extremely slow, and you may cover fifty metres in ten minutes. That is the method working, not failing.
Week one usually gets worse
Nobody warns people about this and it is why most attempts are abandoned on day four. When a behaviour that has reliably worked for years suddenly stops working, the first response is not to give up — it is to try harder. The pulling gets more intense, more frantic, briefly worse than before you started.
This is an extinction burst, and it is evidence the contingency has genuinely changed. It passes within a few sessions if you hold the line. If you give in during the burst, you have taught the most expensive lesson available: that pulling works, but only if you really commit to it.
Equipment, compared honestly
Equipment does not train a dog. It changes the physics while you do the training, which is worth a great deal with a strong dog.
| Kit | What it does | Verdict |
|---|---|---|
| Front-clip harness | Redirects forward momentum sideways | Best single purchase for a strong puller. |
| Back-clip harness | Comfortable, no steering | Fine for a dog that already walks well; mechanically makes pulling easier. |
| Fixed lead, 4–6 ft | A consistent, predictable boundary | What the method above actually needs. |
| Retractable lead | Extends under tension | Teaches that tension yields more lead — the exact opposite lesson. Avoid while training. |
| Head halter | Steers the head, so the body follows | Effective for large dogs, but needs slow, careful introduction or most dogs hate it. |
| Choke / prong collar | Suppresses via discomfort | Does not address why pulling is rewarded, and risks injury to the neck and trachea. Not recommended. |
The mistakes that stall progress
- Training only on the walk you are in a hurry for. Practise on a short, low-stakes outing where being slow costs you nothing.
- Talking through it. Repeating the dog’s name or "heel" while they pull just makes those words background noise.
- Rewarding the return, not the position. If you only treat when the dog comes back from the end of the lead, you have built a loop: surge ahead, come back, get paid. Reward walking beside you.
- No outlet for the energy. A dog that has been indoors for nine hours is not in a state to learn lead skills. Take the edge off first.
Give them a sniffing walk too
A lot of pulling is frustration at never being allowed to investigate anything — which is what a decompression walk is for. Designate part of the walk as their time: loose lead, they choose the direction, sniffing encouraged.
A dog that reliably gets that is markedly easier during the structured part, because the structured part is no longer the only chance they get. Scent work also tires a dog faster than distance does, so the sniffy half is doing more work than it looks.
When it is not pulling
Lunging at specific triggers — other dogs, bikes, cars — is reactivity, not a loose-lead problem, and the method above will not touch it. It needs distance management and counter-conditioning, which is genuinely worth a professional. The tell is that it is directed and sudden rather than constant.
