How To Put On A Dog Harness

Well, the first thing you notice about a dog harness is that the marketing makes it look effortless. The photos show a perfectly still golden retriever standing pretty while an owner clips two buckles. My reality, after ten years of fitting harnesses on reactive shepherds and barrel-chested pit bulls, is a 6 AM wrestling match in a muddy driveway. So when I get asked how to put on a dog harness, the honest answer is that it depends entirely on which harness you bought, and whether you bought it for the right reasons.

I’m Tomás. I’ve fitted over 3,000 dogs with harnesses in my shop, and I’ve owned two German shepherds, Bruno and Kira, who have tested every strap and buckle I recommend. If you’re here because your dog wiggled out of another harness, or because you’re staring at a tangle of straps wondering where the legs go, this guide is for you. I’ve broken down the two most common styles, the exact pitfalls, and which dogs should avoid which design entirely.

Product	Price	Why it won	Why it lost
Julius-K9 IDC	Check price	Genuinely escape-proof for problem dogs, premium canvas, easy over-the-head fit	Chest strap can rub on deep-chested dogs; plastic buckles on some sizes
Kurgo Go-Tech	Check price	Heavy-duty metal clasps, front clip works for pulling	Non-adjustable neck hole fails barrel-chested dogs

How to put on a step-in harness (and why I avoid them)

The step-in style is the most common in box stores. You lay the harness flat, put the dog’s front legs into two holes, then pull it up over the back and clip. Sounds simple. In practice, I’ve watched a hundred owners fight a squirming 60-pound dog who refuses to lift his paws.

The problem isn’t the mechanics. It’s that step-in harnesses rely on the dog standing still. My own Bruno, when he was young, would sit down the second he saw the harness. You can’t step a sitting dog into anything. The design also requires the chest strap to sit correctly across the sternum, and if you miss that by an inch, the whole thing shifts sideways the moment the dog pulls.

If you own a dog that hates having paws touched, skip the step-in entirely. You’ll spend more time wrestling than walking.

How to put on an over-the-head harness (the Julius-K9 method)

The Julius-K9 IDC is the harness I recommend when nothing else works. I’ve seen it on Shar-Peis that slipped every other harness on the market. The deep chest piece and snug fit make backing out nearly impossible. One owner put it perfectly: “He could not escape the IDC harness.”

The putting-on process is the real advantage. You don’t thread legs through anything. You just pass the head through the neck hole, then clip the two side buckles. It goes on and off super easy. For owners with a squirmy 100-pound Anatolian Shepherd, it’s the difference between a pleasant morning walk and a wrestling match.

Here’s the exact sequence I use with Bruno:

1. Loosen both side straps completely.
2. Hold the harness by the top handle, open the neck hole wide.
3. Slip it over the dog’s head, like putting on a t-shirt.
4. Let the chest piece settle behind the front legs.
5. Clip the left side, then the right side.
6. Tighten both straps evenly until you can fit two fingers flat under the strap.

The top handle is genuinely useful. I’ve used it for vet visits, for pulling a dog back from a curb, for grabbing a dog before it lunges. One reviewer noted it’s “well positioned and durable.” I agree.

But there’s a catch. The strap under the chest can rub under the front legs. One service dog handler mentioned it, and I’ve seen it on dogs with deep chests. The fix is to adjust the strap so it sits slightly looser, but that creates a tradeoff with escape-proofing. You have to find the sweet spot for your dog.

The sizing can also be confusing. An English bulldog owner ordered a size 1 for a 35-pound puppy and found it waaay too big. The medium/0 fit perfectly. Measure your dog, not your guess.

One more thing: the leash clip. If you have one of those new-style clips, it might not fit over the ring. Check your hardware before you buy.

How to put on the Kurgo Go-Tech (and the fit problem)

The Kurgo Go-Tech has the best hardware I’ve tested. The metal clasps are heavy-duty and will not break. One buyer said they’d “gone through so many harnesses just because he chews off the fasteners,” and this one survived.

The putting-on process is a hybrid. You slip it over the head like the Julius-K9, but the straps adjust differently. The front clip is the standout feature for pulling. Multiple buyers confirmed it: “The front attachment really helps your dog stop pulling.” I’ve used it on my own reactive shepherd, and it makes a difference.

Here’s the problem: the neck hole isn’t adjustable. That’s the dominant complaint, and it’s a dealbreaker for a lot of dogs. “The neck-hole isn’t adjustable at all, my dog has a big ribcage but skinny everything else, and the front end of the harness moves around a lot while he is wearing it.”

I’ve seen this exact problem in my training. A harness that shifts and slides is a harness that doesn’t control the dog. Pit bulls have it especially bad. “It was the right size on the waist, but was entirely too big on her chest and she almost pulled right out of it.” Another pit owner had to “sew it smaller” until the dog grew into it.

If your dog has a standard proportion, say an American Eskimo, the Kurgo is a solid choice. If you own a pit bull or a barrel-chested dog, look elsewhere. The metal clasps don’t matter if the harness slides off sideways.

The front clip question

The front clip is the single most useful feature for a pulling dog, and it’s still not standard. The Kurgo has it, and buyers confirm it works. The Julius-K9 doesn’t have a front clip on the IDC. The ring is on the back.

The physics is simple. When the dog pulls forward, the leash pulls them sideways. They learn to stop pulling because pulling is uncomfortable. It’s not magic, but it works. I’ve attached leashes to front clips on hundreds of dogs.

If you’re choosing between the two, the front clip is the deciding factor for a puller. The Julius-K9 will keep the dog from escaping, but it won’t fix the pulling. The Kurgo will fix the pulling, but only if the harness fits properly.

What I actually do at 6 AM

I don’t track prices day to day, so I won’t pretend to know next week’s. But I know what I reach for when Bruno is lunging at the door.

The Julius-K9 is the safer bet for problem dogs. It’s more expensive, but it’s genuinely escape-proof and the construction is premium. The canvas holds up, the stitching survives, and the Velcro patch system is a nice touch. You can customize it, add glow-in-the-dark patches, even get one that says “I rescued my human.” A service dog handler has used it daily for four years and it’s “still in really great condition.” At $40, that’s less than three cents a walk.

The Kurgo is the better choice for a dog that chews through harnesses. The metal clasps are nearly indestructible. But check the sizing chart against your dog’s actual measurements, not their weight. A 20-pound terrier mix with a big ribcage and a skinny neck is not the same as a 20-pound chihuahua.

The honest bottom line

If your dog slips every harness you try, get the Julius-K9. It’s the closest thing to escape-proof I’ve tested. If your dog pulls like a freight train and has a standard body shape, get the Kurgo. The front clip works.

If your dog is barrel-chested with a skinny neck, neither is perfect. The Julius-K9 might rub, and the Kurgo won’t fit. Measure your dog’s chest and neck before you buy anything, and don’t trust the weight-based sizing charts. They’re wrong more often than they’re right.

I’ve been doing this for a decade. The harness that works is the one that fits your specific dog, not the one with the best marketing photos.
