Julius K9 IDC Powerharness: Style and Colors

For the purpose of this review I’ll be looking at the IDC Powerharness only, there are other styles available.

The IDC Powerharness is a shaped top piece that sits on your dogs back think of a saddle type shape. It follows the shape of your dog and features two straps one that goes around our dogs rib area and another that goes around the front just above the shoulders but below the throat see image below.

I purchased the IDC Powerharness in red because it’s one of my favourite colours and Lilly was wearing a red collar at the time. Though it does come in 20+ colors or designs including the GB Flag and US Flag to name a few.

If that’s not enough personalization the IDC Powerharness comes with two Velcro glow in the dark patches that can be customised with your dogs name or a message of your choice. Though these do cost extra depending on size and whether your message is bespoke or ready made.

Julius K9 IDC Powerharness: Materials

The IDC Powerharness is made in Germany and uses OEKO-TEX anti allergenic lining which makes it friendly to both human and canine skin! Unfortunately, they don’t disclose a full materials list so I cannot go into much detail on this. However, the D ring featured on the back of the harness is super strong and honestly is one of the best D rings I’ve seen on a harness!

Julius K9 IDC Powerharness: Key Features


One of the features that drew me to the IDC Powerharness was the glow in the dark patches and general reflective properties. Mostly for the fall and winter walks which are almost always in the dark. Surprisingly the glow in the dark patches are really effective and only need to be in a well lit environment for a short time to work! The reflective aspect is built into the harness itself with reflective top stitching around the main body section and a reflective strip on the chest strap.

If you need more visibility then you can also add further lights via loops near the handle and above where the side bags would attach. These are an add on and would be an extra cost. I personally haven’t used this option so cannot comment further.

Built in Handle

Another brilliant feature that’s super helpful for me and Lilly as we often walk the local mountains, which means getting over a number of  stiles. The handle is really handy for helping Lilly get over safely especially when there’s cattle or sheep roaming and Lilly has to be on lead! It’s also really handy for socialization as you can hold your dog in the sit position and encourage good social behaviour without jumping up etc. For security there is a small security tab that holds the handle down when not in use.

Option to add side bags

If your going on a long walk or need your dog to carry some supplies then the IDC Powerharness does have to option to attach two side bags. These are an add on and come at an extra cost, I personally haven’t used these so I cannot comment on them.

How does it wash?

We’ve had the IDC Powerharness now for nearly 4 years and in that time its walked mountains, been rolled in multiple dead and smelly substances and done its fair share of mud surfing! I’m pleased to say that it has held up really well! All the photos on this blog are of our actual harness which is why there are no tags attached. I tend to just pop it in the sink and scrub away and I’ll be honest it does come up well. It dries pretty quick too which is always an added bonus. I advise that you always follow the manufacturer’s care instructions which are included on the label stitched into the harness.

Is it Value for Money?

When I ordered the IDC Powerharness back in 2016 it was £40 including shipping and tax for the size 2 harness, with no optional extras. When you sit down and spread that cost over the time I’ve had the harness it works out at £10 a year, which is nothing really! The harness is still in fantastic condition and is really hard wearing so I’d definitely consider getting another if I needed to.

I’ve read that this type of harness limits my dogs movements, is that true?

This is a touchy area to be honest and for a while I did stop using my IDC Powerharness due to this concern. However, I have since started using it again after reading important literature which has studied this claim in depth. I would suggest you look at this data yourself here.


If you were to  ask me would I purchase the Julius K9 IDC Powerharness again, I would have to really think about it. Not because there’s anything wrong with it, but because I’ve become a bit of a harness hoarder. However, if I didn’t have another harness I would definitely purchase another. The handle is super useful and the reflective and glow in the dark properties are perfect for walks in the dark or poor conditions.

So I do think one of the best on the market, though please be cautious there are some pretty convincing fakes on the internet. I highly recommend you purchase from a reliable retailer!
