Julius K9 IDC Powerharness Dog Harness

Give your dog nothing less than the best! The Julius K9 IDC (Innova Dog Comfort) Powerharness is the WORLD'S BEST dog harness designed for pet dogs and working dogs of all ages and sizes! Not only does the harness look fantastic on all dogs, its ergonomic design also prevents chafing and eliminates strain on your dog's neck and back during walks, training and working conditions.

Harness Features:

The harness is made from authentic European materials for the ultimate durability. The main section of the harness is made from water-repellent nylon and a breathable inner-lining that allows your dog's skin to breathe. The adjustable chest strap is made from strong nylon webbing and features a large reflective strip for increased visibility during low-light hours. The body strap is also adjustable and is secured with a tough Julius K9 buckle that's been tensile tested up to 350kg. A closeable handle is attached to the top for direct control when needed. You'll also receive a free pair of glow-in-the-dark JULUS K9 labels for increased visibility to others during low light hours.


Taking your Dog's Measurements Correctly

It's important to measure your dog correctly to select the best harness size for your dog. Place four fingers behind your dog's front legs and using a flexible measuring tape, measure the circumference of your dog's chest from that point (as seen in the diagram below).

If your dog is between two sizes, choose the harness size that has the most adjustability or use the dog weight as a secondary guide. If you have any questions about which harness is best for your dog, please measure your dog's chest circumference and give us a call on 1300 483 179.

Fitting the Harness on your Dog

If your dog's harness straps are too loose, your dog may be able to shuffle out of the harness, however, if the harness straps are too tight, the strap buckle will rub against your dog's skin around the armpit area which may lead to chafing after regular use.

Correct Fitting

A properly fitting harness will fit comfortably around your dog and you will be able to easily slide your fingers between the harness and your dog's back. The incorrect fitting may lead to discomfort, chafing and injury.


Optimum Load Distribution

Each IDC Powerharness size has a customised chest strap designed for effectively distributing pressure across the strongest part of your dog's body.

*Please Note - some differences exist between the range:

  • Rubber strap closure handle to hold down the handle (Not available on Mini / Mini-mini)
  • Hook and loop pad to secure the handle (Not on Size 0-3)

Well Made Excellent Fitting Harness

By: on 15 April 2019
I saw these harnesses on all the pampered UK pooches so my two cairn terriers needed to have one. I am definitely not disappointed with this purchase. They are extremely well made. Since the harness is so adjustable it fits like a glove. I ordered the extra Y piece that allows for front lead attachment and it works well. I love the customisable labels too. Now I need to figure out how to get a customised embroidered name label! I will definitely get some for my other two dogs now.

Best Harness EVER!

Got my Julius harness and can't rave about it enough. I have an extremely large, strong Doberman and he used to take me for a walk. The harness fits perfectly and walking him is now a pleasure. The stress on his neck with regular collars and the rubbing under his arms from other harnesses are now a thing of the past. I highly recommend this harness. Oh and love the custom labels ....couldn't decide between BOSS or SECURITY so got both.

Julius K9 Power Harness is one great harness
