The short answer: dogs pull because it works. They want to get to the interesting thing ahead, they move faster than we do, and every time pulling gets them there, the habit is rewarded. It has nothing to do with dominance and everything to do with simple consequences. Fix the consequences — make pulling stop working and loose-leash walking pay — and the pulling fades.
It takes consistency more than cleverness. Here’s the mechanism, then the method.
Why pulling is the default
Three things stack up:
- Dogs walk faster than humans. Left to their own pace, most dogs trot. Our stroll feels frustratingly slow, so they lean into the leash to speed us up.
- The opposition reflex. Dogs instinctively pull against pressure. When the leash goes tight, the dog’s reflex is to pull harder — not to yield. So a tight leash physically encourages more pulling.
- It gets rewarded, every time. The dog pulls, the lamppost gets closer, the sniff happens. From the dog’s side, pulling is a strategy with a near-perfect success rate. Of course it persists.
Understand that last point and the fix becomes obvious: pulling has to stop delivering the reward.
The core method: pulling stops the walk
The single most effective principle is that a tight leash means forward motion ends, and a loose leash means it resumes. Two common versions:
- Stop-and-stand. The moment the leash goes tight, you stop dead. Don’t yank, don’t scold — just become a tree. Wait. The instant the leash slackens (the dog turns, steps back, or looks at you), say “yes” and walk on. The dog learns: tight leash = nothing happens, loose leash = we move.
- Turn and go the other way. When the dog forges ahead, calmly turn and walk the opposite direction. The dog discovers that pulling doesn’t control where you go. Reward when it catches up into position.
Both are slow at first — your early walks may cover fifty metres in fifteen minutes. That’s normal and temporary. You’re not really walking; you’re teaching.
Reward the position you want
Stopping the reward for pulling is half the job. The other half is paying generously for the behaviour you do want. Whenever the dog is walking with a loose leash near your side, mark and treat. Be lavish early on. You’re building a new default, and the dog needs to discover that the spot beside your leg is the most rewarding place to be.
A clear verbal marker (“yes”) or a clicker makes this faster, because it pinpoints the exact moment the dog got it right.
Equipment that helps — and what to avoid
Gear won’t train the dog for you, but the right kit makes training easier and the wrong kit makes things worse:
- Front-clip (front-attach) harness. Clips at the chest, so pulling gently turns the dog back toward you instead of letting it drive forward. The best starting point for most pullers.
- A standard fixed-length leash, 1.2–2m. Predictable, so the dog can learn where the boundary is.
- Avoid retractable leashes for pulling problems — they teach the dog that pulling extends its range, the exact opposite of the lesson.
- Avoid choke, prong, and slip collars. They suppress pulling through discomfort rather than teaching an alternative, can injure the neck and throat, and don’t address why the dog pulls.
Why the breed matters
A high-drive, high-stamina dog pulls harder and longer because the reward — getting to the next thing — is more valuable to it. Strong working breeds like a German Shepherd or a Labrador need the training and enough overall exercise that they’re not arriving at the walk over-full of energy. A dog that’s properly exercised has an easier time keeping a loose leash. The walking calculator sets that baseline.
And one practical note: dogs that get to sniff pull less. A walk where stopping to read the hedges is allowed — and used as a reward for loose-leash walking — gives the dog a legitimate way to get what it wants without dragging you to it.
Consistency is everything. If pulling works even one walk in five, you’re training the dog to keep trying. Every person who walks the dog has to play by the same rules. Get that alignment, stay patient through the slow first fortnight, and loose-leash walking becomes the new normal.
