Two Dog Harness Types I Avoid
Many dog owners choose a harness without realising how much its shape can affect comfort and movement.
That is not a criticism. It is usually a reflection of what is popular, what is sold in shops, or what gets recommended without much thought about how the design affects the dog.
Some harnesses look sturdy. Some look clever. Some are marketed as helping with pulling. But not all dog harnesses are designed with a dog’s comfort, movement or learning in mind.
In this article, I’ll explain two dog harness types I avoid, why I avoid them, how to check whether your dog’s current harness may be causing a problem, and what I recommend instead.
Quick Answer: Which Dog Harnesses Do I Avoid?
| Harness type | My view | Why |
|---|---|---|
| Horizontal strap across the shoulders | Avoid | The strap can sit across the shoulder area and may interfere with natural movement. |
| Tightening “no-pull” harness | Avoid | It works by adding pressure or discomfort when the dog pulls rather than teaching loose lead walking. |
| Well-fitted Y-front harness | Recommended | It keeps the shoulders clearer and should allow more natural movement when fitted correctly. |
Why Harness Choice Matters
When people think about choosing a dog harness, they often focus on control. Will it stop pulling? Will it stop the dog slipping out? Will it feel secure?
Those things matter, but so does movement.
A dog’s front end needs to move freely for comfortable, natural walking. If a harness sits in the wrong place, it can affect stride, shoulder reach and overall comfort. That is why I always look at how a harness is shaped, not just whether it looks practical.
In my work as a professional dog trainer, I regularly see dogs wearing harnesses that are popular and widely available but are not especially well suited to the individual dog’s shape or movement.
Dogs Trust also notes that harnesses can help reduce the risk of neck injury, but they are clear that dogs still need to be taught to walk nicely on a lead. Equipment should support training, not replace it.
If you have heard that using a harness automatically encourages pulling, read Do Harnesses Teach Dogs to Pull?. The short answer is no. Pulling is a learned behaviour, not something created by the shape of a comfortable harness.
Dog Harness Type 1: A Strap Across the Shoulders
The first type I avoid is a harness with a straight strap running across the front of the shoulders.
This style is extremely common. It is popular, widely available and often recommended simply because people do not realise there may be a better option.
The problem is where that front strap sits.
Dogs move their front legs forward with every step they take. If a harness strap sits directly across the shoulder area, it may limit how freely that movement happens. Even if the dog can still walk, that does not automatically mean the design is ideal.
This is why I prefer a harness shape that keeps the shoulders clearer and allows the dog to move more naturally.
Another issue with some of these styles is that they can be surprisingly easy for dogs to back out of, especially if the fit is poor or the dog panics and reverses sharply. That can become a safety issue very quickly.
Dog Harness Type 2: Tightening “No-Pull” Harnesses
The other harness I avoid is the tightening “no-pull” harness.
These are often marketed as a simple answer for dogs that pull. But the way they work is by tightening around the dog’s body when tension goes onto the lead.
Rather than teaching loose lead walking, they work by adding pressure or discomfort when the dog pulls.
That is the part I am not comfortable with.
Yes, these harnesses may reduce pulling in the moment. But that is not the same as teaching the dog how to walk comfortably beside you. It is making pulling feel less comfortable rather than showing the dog what you would like them to do instead.
I would much rather teach the skill of loose lead walking properly and use equipment that keeps the dog safe and comfortable while they learn.
Is pulling making walks difficult?
My Outstanding Obedience online course includes a practical, force-free loose lead walking technique that you can work through at your own pace.
For support tailored to your individual dog, you can also book a one-to-one dog training consultation.
How to Tell if Your Dog’s Harness May Be a Problem
A harness does not have to cause an obvious injury before it is worth reassessing. Look at how it sits while your dog is standing and how it moves while your dog is walking.
- The front strap sits directly across the shoulder area.
- The harness rubs behind the elbows or into the armpits.
- The harness twists or rotates around the body.
- Your dog’s stride looks shorter while wearing it.
- Your dog slows down, backs away or avoids having it put on.
- Your dog can reverse out of it when frightened or excited.
- The harness tightens around the body when the lead becomes tense.
One sign on its own does not necessarily prove that a harness is causing discomfort, but it is a good reason to check the fit, design and your dog’s movement more carefully.
What I Recommend Instead
Personally, I prefer a well-fitted Y-front harness.
With a Y-front design, the straps run down the chest rather than straight across the front of the shoulders. That generally allows better freedom of movement.
I also want the chest strap sitting behind the elbows, not rubbing up into the armpits, and I do not want the harness tightening when the dog pulls.
What to Look for in a Dog Harness
- A Y-shaped front that leaves the shoulders clear.
- A secure fit that does not twist or rotate.
- Enough adjustment for your dog’s individual body shape.
- A chest strap that sits behind the elbows without rubbing.
- Room for comfortable movement without being loose enough to escape.
- No tightening mechanism that adds pressure when your dog pulls.
Two options I particularly like are the Ruffwear Front Range Harness for everyday use and the lighter Ruffwear Hi & Light Harness, which can suit dogs who prefer less equipment on their body.
If your dog is an awkward shape, deep chested or difficult to fit, the fit matters just as much as the general design. Always assess the harness on the individual dog rather than relying only on the size shown on the label.

A Harness Is Not a Training Plan
Even the best dog harness will not teach your dog to walk nicely on a lead.
That part still comes down to training, reinforcement and practice.
A comfortable, well-fitted harness can help by reducing unnecessary discomfort and giving you a better setup to work from. But it is not the thing doing the teaching. You are.
That is why I like pairing a good harness with sensible handling and the right lead setup. A Halti Training Lead gives you several useful configurations without relying on a tightening harness to control the dog.
The simple takeaway: choose a harness that leaves the shoulders clear, fits securely without rubbing and does not tighten when your dog pulls. Then teach loose lead walking as a skill rather than expecting the equipment to do the teaching.
FAQ
What type of dog harness is best?
In general, I prefer a well-fitted Y-front harness that leaves the shoulders free to move and does not tighten when the dog pulls. The best harness must also suit the individual dog’s body shape and remain secure without rubbing.
Are no-pull harnesses bad for dogs?
Some harnesses labelled “no-pull” simply provide alternative lead attachment points, while others tighten around the dog when they pull. I avoid tightening designs because they rely on pressure or discomfort rather than teaching loose lead walking.
Are Julius K9 harnesses bad for dogs?
Julius K9-style harnesses commonly use a horizontal strap across the front of the shoulders. My concern is the position of that strap and its potential effect on natural shoulder movement. I prefer a correctly fitted Y-front design that keeps the shoulder area clearer.
Do harnesses teach dogs to pull?
No. Dogs pull because moving forwards is rewarding and because they have not yet learned the skill of loose lead walking in that environment. A harness does not teach pulling. Training and reinforcement teach the behaviour you want instead.
