Why Your Dog Pulls on the Leash and How to Fix It
Your dog pulls on the leash because of opposition reflex — a natural response where they pull against any force applied to their body. When a puppy first feels leash tension, they instinctively pull harder in the opposite direction. Most owners unknowingly strengthen this reflex by using harnesses or jumping to corrections without first teaching the dog to follow leash pressure. The solution is a systematic 5-phase training progression: engagement, leash pressure desensitization, muscle memory development, accountability, and generalization.
Leash pulling isn’t stubbornness or disobedience — it’s opposition reflex. When your dog feels tension from the leash pulling them backward, their natural instinct is to dig in and pull forward, away from the pressure. Most dog owners make this worse by putting a harness on the dog, which gives them even more leverage to pull. Others jump straight to corrections with a prong collar, but if classical conditioning is already strong (the dog has been practicing pulling for months or years), the correction won’t matter — the dog will pull right through it.
Chad wrote The Ultimate Leash Training Manual to give dog owners a complete, structured system to fix leash pulling in any dog: puppies just learning to walk on leash, adult dogs with years of bad habits, anxious rescue dogs, and even reactive dogs that lunge at everything. The book breaks down the exact 5-phase progression used at Canine Revolution Dog Training in Charleston, SC.
The 5 phases are:
- Phase 1: Engagement — Build sustained focus on you before you ever start leash training. Your dog has to want to pay attention to you.
- Phase 2: Leash Pressure — Desensitize opposition reflex by teaching your dog to follow the leash when tension is applied, not pull against it.
- Phase 3: Muscle Memory Development — Use food lures to teach your dog exactly where to walk in relation to you (the heel position). Walking politely on leash is not natural — you have to teach it just like sit or down.
- Phase 4: Accountability — Once the behavior is taught, establish fair boundaries. Chad uses the “invisible box” concept: imagine a 2×2 or 3×3 foot box next to you that moves with you. If your dog’s head and shoulders stay in that box, they’re good. If they exit it, hold them accountable with leash guidance.
- Phase 5: Generalization — Practice the behavior in progressively more difficult environments so your dog can walk on a loose leash anywhere: the park, downtown Charleston, the farmers market, a friend’s house.
The mistake most people make is thinking training only happens during “training sessions.” If you work on loose leash walking for 10 minutes in your driveway but then let your dog drag you to the car and pull you into the dog park, you’re teaching them that pulling still works in real life. Training is happening all the time. Every walk is either reinforcing good behavior or bad behavior.
Chad also addresses common challenges in the book: dogs that pull toward other dogs, dogs that refuse to walk out of fear, dogs that bark nonstop on walks, scavengers that grab everything off the ground. The system works for all of them because it’s based on how dogs actually learn — classical conditioning (involuntary responses) and operant conditioning (the four quadrants of behavior).
And no, this is not just for big dogs. The same progression works for small dogs — you just lower your hand position when you’re luring. One reviewer complained the book didn’t include pictures of small dogs, but the mechanics are identical whether you’re training a Chihuahua or a German Shepherd.

Frequently Asked Questions
Why does my dog pull on the leash?
Your dog pulls because of opposition reflex, which is a natural instinct. When your dog feels the leash pulling them backward (toward you), their automatic response is to pull harder in the opposite direction (away from you). This reflex is present the first time you put a leash on a puppy. If you don’t address it early and systematically, it becomes a classically conditioned behavior — meaning your dog does it involuntarily, without even thinking about it.
Do harnesses make leash pulling worse?
Yes. Harnesses give your dog more leverage to pull because they distribute the force across the chest and shoulders instead of the neck. If your dog already has opposition reflex and you put them in a harness, you’re making it easier for them to pull harder. Harnesses can be useful in specific contexts, but they’re counterproductive if your goal is to stop leash pulling.
Will a prong collar stop my dog from pulling?
Not if the dog’s pulling habit is already deeply ingrained through classical conditioning. If your dog has been pulling on the leash for months or years, the behavior is so automatic that even an aversive tool like a prong collar won’t override it. The dog will pull right through the discomfort because opposition reflex is that strong. You have to break the classical conditioning cycle first by teaching the dog to follow leash pressure, not just correcting them for pulling.
Is it okay to use food in dog training?
Absolutely. Any good trainer uses food. It’s how you pay the dog and reinforce the behaviors you want. The key is knowing how to titrate your food rewards — when to use them, how much to use, and how to fade them out as the behavior becomes reliable. The mistake most people make is never reducing the food, so the dog can’t perform the behavior without a treat in your hand. A skilled trainer teaches the dog the behavior with food, then systematically removes the food while the behavior stays strong.
What if my dog won’t take treats during training?
There’s a process to build food drive. Most dogs that won’t take treats are either too anxious, too distracted, or haven’t been conditioned to see food as high-value in a training context. At Canine Revolution, we’ve had maybe one dog in the entire history of the business that genuinely would not take food. For every other dog, we have a system to get them interested in food rewards, and once that happens, training accelerates. If you’re working with your dog at home, you have unlimited time to build that drive slowly.
How long does each phase of leash training take?
It depends on the dog and how consistent you are, but engagement and leash pressure training can each be accomplished in a few short sessions if you do them correctly. Muscle memory development takes longer — you’re doing many repetitions over multiple days to classically condition the heel position. Don’t rush it. Accountability and generalization are ongoing. The biggest mistake people make is moving to the next phase before the current one is solid.
Should I let my dog sniff on walks?
That’s up to you, but the key is: don’t let sniffing time turn into pulling time. A good structure is to have a focused walk where your dog is in heel position, then give them a “free” command and let them sniff in a designated area. You might do this at the start of the walk, halfway through, and at the end. The dog learns there’s a time to work and a time to sniff, but they never get to decide to break position and drag you over to a bush.
Can I use this system to walk two dogs at once?
Yes, but you have to train each dog individually first. Once both dogs can walk on a loose leash by themselves, you can start a progression to walk them together. Chad outlines a four-step progression in the book. The principle is the same as any other training: break the behavior into steps, teach each step, then combine them. Walking two dogs is also a powerful tool for addressing dog-to-dog aggression between dogs in the same household — if you can get them to walk calmly side by side under your leadership, it solves a lot of the tension.
