Rock harness long

A multi-use dog harness designed for power transfer when pulling, making it suitable for daily walks and trekking as well as obstacle racing or biking.
Expected delivery in 2 to 5 working days


This all-in-one harness is highly adjustable and versatile, equipped with functional features such as a handle.

With the goal of developing the most versatile multi-use dog harness on the market, we used our experience from dog powered sports to make a harness that also aids with pulling. The support strap at the base of the harness distributes the pressure evenly at top and bottom for optimized power transfer when pulling. This makes the Rock harness long suitable for activities like canicross, bikejoring and skijoring for dogs that are pulling moderately.

The Rock harness long is also a great choice for obstacle races and trekking, as it is equipped with a solid handle. When assisting your dog, their weight is distributed evenly over the entire belly panel.

If you don’t want your dog to pull at all, there is a no-pull attachment point in front in addition to the standard leash connection point at your dog’s back. A leash can also be attached  to the loop at your dog's neck to, for example, provide control when being at a race or in busy environments.

The harness is highly adjustable around the neck and chest. Four side release buckles make it easy to take the harness on or off.

Like the other products in our Rock series, the Rock harness long is made with our unique three-layer material combination, HexiVent, offering excellent breathability and comfort.

The Rock harness long comes in black and is available in sizes XS-XL.

How do I measure my dog for this multi-use dog harness?
Measure your dog’s neck and chest and use the size guide to find the right size. Watch this video to see how to measure your dog correctly.
How to adjust the Rock harness long?

You should be able to fit at least two fingers vertically between the top of your dog’s neck and the harness for a medium sized dog (size M). A bit less for smaller dogs, more for bigger dogs. If using the harness for pulling, the neck opening should be quite snug to allow your dog’s shoulders to move freely.

For medium sized dogs, you should be able to fit at least two fingers vertically between your dog’s chest and the harness. Adjust as even as possible on both sides.

2 fingers rule

How do I use the attachment point in front for mild anti-pull control?
If you don’t want your dog to pull on the leash, you can attach the leash in the front, and then place the leash between your dog’s front legs.
How do I lock the adjustable chest straps?

After initial adjustment for your dog, lock the chest straps by simply threading the end of the strap back through the slip-lock.


Can I attach hiking bags on the harness?
The Rock harness long comes with attachment rails where additional items, such as hiking bags, can be attached. When attaching items to the harness, ensure that the weight is distributed evenly on each side.
