My left shoulder still aches on cold mornings.
That is the lasting reminder of three years spent being dragged down the street by Scout, my Border Collie. At his peak, Scout weighed 28 kilograms and pulled with the focused intensity that Border Collies apply to everything. By the end of our morning walks, my arm felt like it had been used as a tow rope.
I tried everything the internet recommended. I stopped walking every time he pulled. I changed direction constantly. I used a slip lead, then a prong collar on the advice of a trainer whose methods I now deeply regret following. Scout pulled through all of it with cheerful determination.
It took studying animal learning science formally — and eventually building a career around it — to understand why everything I had tried was failing. And more importantly, what actually works.
What follows is the method I now use with every pulling dog I work with. I have applied it across more than two hundred cases in the past four years alone. It works on puppies, adult dogs, and elderly dogs who have been pulling for a decade. It works on tiny Chihuahuas and enormous Great Danes. The mechanics are the same because the underlying learning science is the same.
Why Your Dog Pulls: The Real Explanation
Before covering technique, understanding why dogs pull is essential — because the reason is not what most people assume.
Dogs do not pull because they are dominant. They do not pull because they are trying to be the pack leader. These explanations, popular in certain training circles, are not supported by current behavioral science and lead owners toward techniques that make the problem worse.
Dogs pull for a simple reason: pulling works.
When a dog pulls forward and you follow, the dog has just learned that pulling is the correct behavior for moving toward interesting things. Every walk where you allowed forward movement while the leash was tight has reinforced pulling thousands of times. The dog is not being stubborn or dominant — it is doing exactly what has been consistently rewarded.
Understanding this changes everything. You are not fighting your dog’s personality. You are changing a learned behavior pattern — and learned behaviors can be unlearned.
What You Need Before You Start
The Right Equipment
Front-clip harness: This is non-negotiable for most pulling dogs. A front-clip harness attaches the leash at the dog’s chest rather than the back. When the dog pulls, the attachment point redirects them to the side rather than allowing forward momentum. The physical mechanics work with your training rather than against it.
I use and recommend the Ruffwear Front Range and the PetSafe Easy Walk for most dogs. Both are well-constructed, properly padded, and sized to avoid restricting shoulder movement — a problem with cheaper front-clip harnesses.
A four to six foot leash: Not retractable. Retractable leashes teach dogs that pulling extends their range, which is exactly the opposite of what you are trying to establish. A fixed-length leash of four to six feet gives enough range for normal walking while keeping you in a position to respond to behavior.
High-value training treats: For pulling training specifically, you need treats that are genuinely exciting to your dog — not their regular kibble. Small pieces of cooked chicken, cheese, or commercial training treats that your dog responds to with enthusiasm. You will use a lot of them, especially in the first two weeks.
The Right Mindset
This training takes longer than most owners expect. A dog that has been pulling for two years will not walk politely after three sessions. Expect two to four weeks of consistent practice before you see reliable improvement, and two to three months before loose leash walking becomes the dog’s default behavior.
If you approach each session expecting instant results, you will become frustrated and the dog will sense that frustration. Approach each session as practice — small deposits into a behavioral bank account.
The Method: Stop, Reset, Reward
This is the foundation of everything I teach for pulling.
The Core Rule
When the leash is tight, you stop. Completely. Every time.
Not most times. Not when you feel like it. Every single time the leash tightens, forward movement stops. This is the non-negotiable foundation. Inconsistency is the single most common reason this method fails — dogs are excellent at finding the exceptions to rules, and one in ten exceptions is enough to keep the pulling behavior alive.
Step 1: Start in a Low-Distraction Environment
Do not begin this training on your normal walk route. Begin in your backyard, a quiet car park, or a low-traffic residential street. Your dog cannot learn a new behavior when they are highly stimulated. High-distraction environments come later, after the behavior is established in calm ones.
Step 2: Begin Walking
Start moving. The moment the leash tightens — the moment you feel tension — stop completely. Plant your feet. Do not yank the leash, do not say anything, do not make eye contact. Simply stop.
Step 3: Wait for Slack
Stand still and wait. Your dog will eventually look back at you, move toward you, or shift position enough to create slack in the leash. The moment the leash goes slack — even slightly — mark the moment with a clear “yes” or a clicker click.
Step 4: Reward and Reset
When the dog returns to your side, reward with a treat at your hip — the position where you want them to walk. Then begin moving again.
The treat placement matters. If you reward by reaching forward or bending toward the dog, you are rewarding the wrong position. The treat should always be delivered at your hip, which teaches the dog that the rewarding position is at your side.
Step 5: Build Duration Gradually
In the first sessions, you may take three steps before stopping again. This is normal. Over days and sessions, the distance between stops gradually increases as the dog begins to understand that a loose leash keeps you moving.
The Attention Exercise: Teaching Your Dog to Check In
Stopping when the leash tightens prevents reinforcement of pulling. The attention exercise builds the positive behavior you want to replace it with.
In a low-distraction environment, stand still with treats in your hand. Wait for your dog to make eye contact with you. The moment they do, mark and reward. Repeat until your dog is checking in regularly.
Then begin walking. Every time your dog glances up at you while walking, mark and reward. You are building the habit of your dog checking in with you during walks — which is incompatible with focused pulling toward distractions.
Dogs that check in frequently during walks almost never pull. They are engaged with the handler rather than fixated on the environment.
| Week | Focus | Expected Progress |
|---|---|---|
| Week 1 | Stop every time leash tightens, low-distraction only | Frequent stops, short distances |
| Week 2 | Add attention rewards, slightly more distraction | Fewer stops, dog beginning to check in |
| Week 3 | Longer walks, moderate distraction | Noticeably better, occasional pulling at high distraction |
| Week 4 | Normal routes | Mostly loose leash, reliable in known environments |
| Month 2-3 | Generalization to new environments | Consistent loose leash across contexts |
The Mistakes That Keep Dogs Pulling
Inconsistency
Allowing pulling sometimes — when you are in a hurry, when it is raining, when you are tired — resets the training significantly. The dog learns that pulling sometimes works, which is enough to maintain the behavior. One consistent rule applied imperfectly still beats ten different rules applied randomly.
Wrong Equipment
Continuing to use a back-clip harness or flat collar during pulling training removes one of the most powerful tools available. The physical redirection of a front-clip harness makes a measurable difference in how quickly dogs respond to the stop-and-reset method.
Treating Walks as Exercise Only
During the training period, walks are training sessions first and exercise second. This means moving slowly, stopping frequently, and rewarding generously. If your dog needs exercise during this period, use off-leash play, a long line in a safe area, or a dog park — not leash walks where you are moving too fast to train.
Expecting Too Much Too Soon
Taking a dog that has just learned loose leash walking in a quiet car park and immediately walking them past a dog park is like teaching a child to ride a bike in a driveway and then taking them to a mountain trail. Build the behavior in easy environments before adding difficulty.
When Progress Stalls
If you have been training consistently for three weeks with no improvement, consider these factors:
Equipment check: Is the front-clip harness fitted correctly? The chest ring should sit at the center of the chest, not on the shoulder. An incorrectly fitted harness loses most of its mechanical advantage.
Treat value: Is your dog genuinely motivated by the treats you are using? Test this by offering a treat when your dog is relaxed at home. If they eat it but show little enthusiasm, the treat value may not be high enough to compete with the environment.
Distraction level: Are you training in environments that are too stimulating for the current stage? Go back to a quieter environment and rebuild.
Session length: Pulling training sessions should be short — ten to fifteen minutes maximum. Longer sessions lead to mental fatigue in both dog and owner, and tired owners make inconsistent decisions.
If you have addressed all of these factors and still see no progress, your dog may have underlying anxiety or reactivity that is driving the pulling. This warrants a consultation with a certified professional trainer who can observe the specific behavior in person.
Scout Today
Scout is eleven years old now. His walks are slow — he is arthritic and prefers to sniff everything in detail — but his leash is loose. He checks in with me regularly. He walks at my side on a flat collar with a leash I barely need to hold.
It took about three months of consistent training to transform the dog that dislocated my shoulder into the one who ambles politely beside me. Those three months changed every walk for the eight years since.
Your dog can learn this. The learning science works on every dog. The question is only whether you can be consistent enough to let it.
