Think Harnesses Stop Leash Pulling? Think Again.

Why I Don’t Recommend Harnesses for Teaching Leash Manners

One of the most common things I hear from dog owners is, “My dog won’t stop pulling on the leash.” And honestly, most of the time when they come to me for help, their dog is already wearing a harness.

I get why. Harnesses are everywhere, and they’re marketed as safer, more comfortable, and easier to use. A lot of people feel like they’re the kinder option, and in some situations, they absolutely can be.

But when it comes to teaching a dog how to walk nicely on a leash, harnesses often end up working against you.

If you think about how a dog moves, it starts to make more sense. Harnesses sit across the chest and shoulders, which are some of the strongest parts of a dog’s body. So, when a dog leans into a harness, they can really put their weight into pulling and there’s not much stopping them or giving them feedback that what they’re doing isn’t right. To them, it just works… and it’s comfortable.

There’s actually a reason sled dogs wear harnesses. They’re designed to pull, and those harnesses are built to help them do it efficiently for long distances. So, when we put that same type of tool on a pet dog that already pulls, we can end up encouraging more of the exact behavior we’re trying to fix.

Leash training really comes down to communication. It’s not just about holding your dog back it’s about helping them understand where they should be and what you expect from them. A standard collar, when used correctly, gives you a much clearer way to guide your dog and communicate those expectations. With a harness, that communication often gets a bit lost, and a lot of owners end up just hanging on while their dog pulls them from point A to point B.

I see this play out all the time. A dog comes in pulling like crazy on a harness, we switch the equipment, clean up the timing and handling, and start reinforcing the right behaviors. Pretty quickly, the dog starts to settle in and actually pay attention on the walk. It’s not anything complicated; it’s just clearer for the dog.

Now, that doesn’t mean harnesses are bad. They have their place. They can be helpful for small dogs, dogs with injuries, or certain activities like hiking or tracking. But if your goal is to stop pulling and have a calm, controlled walk, a harness usually isn’t the best place to start.

At the end of the day, the tool you’re using should make it easier for your dog to do the right thing…not easier for them to keep practicing the wrong one. If your dog is still pulling, it’s worth asking whether your current setup is actually helping you communicate or just making pulling more comfortable for your dog and a bad day for your shoulder.

And once that communication clicks, everything tends to get a whole lot easier…for both of you.
