Front Clip or Back Clip? How to Use Both Rings on a No-Pull Harness

Here is the short answer. Clip the lead to the front ring on your dog's chest when your dog pulls, when you are training, or when you are walking somewhere busy. Clip it to the top ring on the back when your dog already walks on a loose lead, or when you are running, hiking, or letting them move freely on a long lead.

Most people never use the front ring. The top ring is the obvious one, it sits right there on the dog's back, and it is what everyone does by default. Then the dog pulls anyway and the owner decides the harness does not work.

The harness is fine. The ring is wrong. And there is good research showing that a back connection can actually make pulling worse, not better.

The Fur King Ultimate No Pull Dog Harness has both attachment points for exactly this reason. Here is how to use each one.

Quick Reference: Which Ring, When

Why the Ring You Choose Changes Everything

This is not a marketing distinction. The two rings work through completely different physics.

What the top ring actually does

When the lead attaches behind the dog's shoulders, every pull applies force along the dog's spine, pointing straight ahead. Your dog leans forward, the harness pushes back, and the dog leans harder.

This is the same geometry used in sled dog harnesses. It is designed to help a dog pull efficiently. That is not a flaw in your harness, it is just what a rear attachment point does with force.

There is a well-documented reflex behind it. Dogs, like most animals, push back against steady pressure rather than yielding to it. A rear connection gives them a stable surface to push against with their whole chest and shoulders, which is the strongest part of a dog.

What the front ring actually does

When the lead attaches at the chest, a pull no longer runs along the spine. It runs across the front of the dog and off to one side, so the dog's own forward momentum rotates their chest back toward you.

There is nothing to brace against. The harder the dog pulls, the more they turn. No correction, no pain, no yanking. The dog simply arrives back facing you and the walk continues.

That redirection is also the reason a front clip is useful for reactive dogs. You can turn the dog's body away from a trigger before they lock on, which is much easier than trying to recover once the barking has started.

What the Research Actually Says

This is an area full of confident opinions and very little cited evidence, so it is worth being specific about what has been measured.

Front connections reduce pulling

Johnson and Wynne (2024, PeerJ) fitted a strain gauge to the lead and measured pulling force every quarter second across five minute walks with 23 shelter dogs, comparing four types of equipment. Dogs pulled significantly more on a martingale collar than on any other option tested, including the front connection harness.

Notably, the front connection harness was not statistically different from the aversive options in the study. It achieved comparable pulling reduction without the aversive.

Back connections can increase pulling

Shih and colleagues (2021, Frontiers in Veterinary Science) tested 52 shelter dogs on a neck collar against a back connection harness. When dogs were motivated to reach food, they pulled harder and more steadily on the back connection harness than on the collar.

A 2025 review in Animals by Cavalli and Protopopova reached the same conclusion across multiple studies. Dogs pull more on a back clip than on a collar, while front clips measurably reduce pulling.

The honest caveat about front clips

The same review raises a fair point that most harness articles skip. Work by Dowdeswell and Churchill found front clip Y shaped harnesses had the greatest effect on elbow extension, and Lafuente and colleagues found Y shaped back clip harnesses restricted shoulder movement less than some alternatives.

In plain terms: a front connection changes how your dog moves, because that is exactly how it works. For a twenty minute suburban walk with a dog that pulls, that tradeoff is clearly worth it. For a ten kilometre trail run, it is not. Use the front ring for control, and the top ring when your dog needs full range of motion.

What about head collars

They do reduce pulling. The same review notes that dogs on head collars showed stress signs including lowered heads and ears, crouching, fighting the lead, and pawing at their noses. That is why most trainers now reach for a front clip harness first.

When to Use the Front Ring

• Your dog pulls, at all, ever
• You are actively teaching loose lead walking
• You are walking on a narrow footpath or near traffic
• Your dog lunges or barks at other dogs, bikes, or skateboards
• Your dog is strong enough to pull you off balance
• You have a new rescue and do not yet know how they walk
• You are walking more than one dog at once

When to Use the Top Ring

• Your dog already walks on a loose lead
• You are running or cycling with your dog
• You are on a bushwalk or beach with a long lead
• Your dog is a puppy still learning to accept a harness at all
• The front lead keeps tangling in their front legs
• You are using a seatbelt attachment in the car for a stationary dog

The Setup Almost Nobody Uses: Both Rings at Once

A double ended lead clips to the front ring and the top ring at the same time. It is the standard tool for trainers working with strong pullers, and very few pet owners know it exists.

Two connection points give you something a single point cannot: you can steer from the front and support from the back in the same motion, and you can shift the weight of a pull between the two rather than letting it all land in one place. It also stops the harness from twisting sideways when a big dog hits the end of the lead, which is the most common complaint about front clips.

The Fur King Ultimate No Pull Dog Harness supports this out of the box, because both rings are already there. All you need is a double ended lead.

Fitting Comes First, or the Ring Does Not Matter

A front clip on a loose harness does almost nothing. The harness rotates instead of redirecting the dog, and you end up steering a piece of fabric rather than a dog.

The two finger rule

You should be able to slide two fingers flat under any strap, and no more. If your whole hand fits, it is too loose. If you have to force one finger, it is too tight.

Measure the chest, not the belly

The measurement that matters is chest girth, taken around the widest part of the ribcage just behind the front legs. Not the waist, not the neck.

If your dog measures between two sizes, size up and tighten the adjusters. Sizing down leaves no adjustment range and puts pressure in the wrong places.

Check the front strap sits low

The chest strap should sit across the breastbone, not up against the throat. If it has ridden up toward the neck, the harness is too loose or the size is wrong, and you have lost the mechanical advantage the front ring gives you.

Tips for Getting the Most Out of a Front Clip

• Use a lead of about 1.8 metres. Too short and the dog cannot turn, too long and the lead drags under their legs.
• Hold the lead with slack in it. The front ring works on the dog's own momentum, so a permanently tight lead removes the effect entirely.
• Stop moving when the lead goes tight, and start again when it loosens. The harness manages pulling. It does not teach loose lead walking on its own.
• Reward your dog for being beside you, not just for stopping a pull. Most owners only give feedback when something goes wrong.
• Expect a strange few minutes. Some dogs walk oddly on a front clip for the first session while they work out where the pressure is coming from.
• Run the lead over the dog's shoulder, not under their chin, if it keeps catching their legs.
• Swap to the top ring once the pulling has genuinely stopped. The front ring is a training tool, not a permanent setting.
• Check the fit every few weeks. Straps loosen, dogs gain and lose condition, and puppies change shape fast.

What If It Goes Wrong

What if my dog still pulls on the front ring? Check the fit first, because nine times out of ten it is a loose harness. Then check your lead hand. If you are holding constant tension, the dog has something to brace against and you have recreated the back clip problem at the front of the dog.

What if the lead keeps tangling in their front legs? Shorten your lead slightly, hold it higher, and run it over the shoulder on the side you are walking. If your dog is small and low to the ground, a double ended lead solves it properly.

What if the harness twists sideways when they pull? That is a fit issue or a very strong dog on a single front point. Tighten the chest and girth straps evenly, and consider the double ended setup so the force is shared between both rings.

What if my dog seems worse on the front clip? A small number of dogs find the chest redirection confusing at first and get bitey with the lead or freeze. Go back to the top ring for a week, reward them for walking calmly in the harness, then reintroduce the front ring on a quiet street rather than a busy one.

What if I am worried about their shoulders? Use the front ring for controlled walks and the top ring for running, hiking, and anything high mileage. The evidence on gait effects is about sustained movement, not about a twenty minute walk around the block.

What if my dog can back out of it? The harness is too loose or too big. Re-measure the chest girth, tighten the straps to the two finger rule, and check the strap in front of the shoulders is snug. This matters most for narrow headed breeds like Greyhounds and Whippets.

FAQ: Front Clip and Back Clip Harnesses

Is a front clip harness cruel or harmful?

No. A front connection redirects your dog using their own momentum rather than applying pressure to the neck or causing discomfort. The research on welfare indicators found no clear evidence of poorer welfare from front connection harnesses, in contrast to head collars where visible stress signs were recorded.

Does a no-pull harness stop pulling on its own?

It reduces it significantly, but it manages the behaviour rather than teaching the alternative. Pair the front ring with stopping when the lead tightens and rewarding your dog for walking beside you, and the pulling actually goes away.

Can I leave the lead on the front ring permanently?

You can, but it is better not to for active dogs. Front connections have the most effect on front leg movement, so use the front ring for control and the top ring for running, hiking, and long distance walking.

Which ring should I use for a puppy?

Start on the top ring. A puppy is learning to accept wearing a harness at all, and that is enough for the first few weeks. Move to the front ring once they are comfortable and are strong enough to pull.

What is a double ended lead and do I need one?

It is a lead with a clip at each end, attaching to both rings at once. You do not need one, but it is the best setup for strong pullers and it stops a front connection twisting the harness sideways.

My dog only pulls at the start of the walk. Which ring?

Front. The first five minutes are when arousal is highest and most pulling happens. You can switch to the top ring once they have settled, and many owners do exactly that.

Does the handle on top replace the lead?

No. The reinforced handle is for short term control and for lifting, such as helping an older dog into the car or over a gate. It is not a walking attachment.
