Julius-K9 IDC® Powerharness

About Julius-K9

This company is close to me because they started as a small, Hungarian family business in 1997 and since then, they sold more than 7 million products - many to police units and for service dogs. They are also one of the few companies who do extensive testing on their products and conduct researches to understand better what works best for the dogs.

Norwegian Harness vs. shoulder joint

Before jumping in the review of this harness, I have to stop here for a second and talk about the common misconception that all Norwegian style harnesses are restricting shoulder movement; therefore, they shouldn’t be used.

Many people seem to associate the restricted shoulder movement with running in a pencil skirt - they think that the dogs are not able to move their front legs freely when wearing a Norwegian harness. First of all, the proper adjustment for any harness is essential. Norwegian harnesses are designed to sit farther behind the front leg (not in the armpits!) leaving enough room for the shoulder to move back. If it is positioned like that, there is no way the harness can restrict the shoulder movement and would put pressure on the joints unless the dog pulls. If the dog’s legs are moving freely, nothing is pulling the harness back, so there is no way it can put any pressure on the front strap. The Norwegian harnesses shouldn’t be a tight fit around the front of the dog.

And what if the dog pulls and there is stress on that strap? Probably Norwegian harnesses are not your best option in this case or if you are doing canicross or bikejoring regularly. But does this mean this isn’t a good harness? No, you just have to know when and how to use it.

Everyone has different priorities when choosing a harness, but it is essential to apply some critical thinking when you see people talking about negative health effects in every second comment when this topic comes up.

IDC® Powerharness Review

This is a high-quality harness with tested materials, made with attention to all the small details. The saddle part comes in a lot of different colors and patterns; it is tough to pick only one! The front strap is held together by a strong velcro. At first, this doesn’t seem like a safe solution, but it holds well. Adjusting it can be harder than using a slider as on the TLH5753 harness, but it will stay there for sure, doesn’t get looser by time. The big buckle of the chest strap is also sturdy and easy to use.

The front strap and the edge of the harness are reflective which makes it highly visible in the dark. All of the harnesses come with phosphorescent, interchangeable “Julius-K9” patches.

I am most impressed with the handle on the back. You can choose to cover the stainless steel ring and/or the handle with a rubber strap to make it safer when your dog runs free on a hike and would have a chance to get stuck on something.

Since I tested the similar TLH5753 harness before, I was surprised about the big difference of the saddle material of the two harnesses. On pictures, they don’t look that different, but they are. First I liked the soft, sponge-like material of the TLH5753 harness but I quickly realized that they collect mud, water and dog hair like a magnet. It wasn’t easy to keep it clean and also got heavy after a swim or a rainy walk, making the harness slide to the side of the dog. The material of the K9 harness is thinner and more firm. It doesn’t collect the dog hair and doesn’t get as heavy when it is wet. Probably this is the reason why I haven’t had much trouble with the harness sliding on the dog as I described in the review of the TLH5753 harness.

One thing to mention is that on my sized 0 harness, the velcro overlaps a little bit with the attachment of the front strap. This isn’t an issue it’s just weird when Julius-K9 pays attention to all other small details.

How is the IDC harness different than the other Norwegian harnesses?

I honestly had a hard time figuring out the difference, but once you see it out, it is so clear. Most of the Norwegian style harnesses (as the older version of this IDC harness) have a vertical front strap as you can see it on the right side of the picture below. This can work well for many dogs, but in some cases, the front strap can sit too high up and put pressure on the dog’s neck. This can be solved by using a chest pad that you can buy separately from the company to pull the front chest lower. The IDC harness has this functionality “built-in”.

The above picture is a screenshot from this video where they explain all the differences between the “old type” K9 harness and the IDC Powerharness.

Proper adjustment

Proper adjustment is always crucial with any dog gear, but it seems harder to find the optimal length of the straps in case of the Norwegian harnesses because the big “saddle” part will determine how high up the front strap will be positioned (unless you use a chest pad). When we first got these harnesses, I made small adjustments on the straps during every walk to figure out how to hold the harness in place without restricting the shoulder movement. If you don’t leave enough room behind the front legs, the dog will not be able to comfortably walk in the harness even off-leash since the front part is pulling the shoulders back when the dog steps. Fortunately, the straps give you a wide range to customize the harness and find the best fit for your dog. I appreciated that this harness came with a useful guide explaining the optimal position. Below you see two pages of that description made by Julius-K9:

In general, the best way to position these harnesses is to have the front strap just below the neckline (shouldn’t put pressure on the dog’s neck when sniffing the ground) and the chest strap a few inches behind the front leg. When the dog runs or trots, the chest strap shouldn’t rub against the back of the front legs.

Review Summary

This harness is probably the most famous Norwegian harness and for a reason. The quality material makes it easy to use, easy to clean and it is also a durable one. When choosing the harness, be sure to follow the sizing chart and accurately measure your dog because while both straps are adjustable, the size of the saddle also determines the position of the harness.

Functionality Review

No-pull correction: I wouldn’t suggest using it if your dog pulls - it will not help to teach better leash manners, and it can also hurt the dog’s shoulders.

Running/Biking (as an occasional hobby, buy specific equipment if you want to get into it seriously) Only use it if your dog is perfectly trained and only runs next to you without putting ANY pressure on the leash and be sure the harness leaves enough room for the front legs. No bike-jorning, sledding, etc. with this harness!

Hiking: The handle is a big help to hold your dog on mountains or lift him/her if needed. Keep in mind that the harness has to be correctly adjusted to be sure the dog is not sliding out when lifting - if needed you can purchase a chest pad for additional safety. As always, be sure the dog can run, jump comfortably in it without any restriction before going for a hike!

City walk: If your dog gets scared easily, buy a chest pad to make it safer. The custom velcro text can be a big plus in a busy neighborhood to let other people know if your dog is reactive/shy/friendly etc. or to put your contact information on it in case your dog would run away. You can buy these from Julius-K9 in different colors and even with phosphorescent or reflective text.

Easy to put on/adjust: simple: you just have to put it over the head and use one buckle. It is excellent for big headed dogs or for those who are afraid of putting a tight harness over their head. I found it useful for walking up to agility training (where you remove it for the training and putting it back after) or for a quick walk when you want to put something on the dog quickly and be able to remove it with one click.

Visibility: great! It has bright colors and reflective parts all over - I think that the visibility and the custom velcro text are the most significant features of this harness.

Where to buy

You can buy all their products on their website and can probably also find retailers and stores in your country.

The leash and collar on some of the photos are also from Julius-K9, check out the review of the Color & Gray Collar and leash set on the link!
