Dog harness: how to put it on and adjust it correctly?

Fitting your dog with a harness may seem simple, but to ensure comfort and safety, it's essential to get it right. Whether you're going for a leisurely stroll or a more active outing, a well-fitted harness makes all the difference. Here, we'll explain step-by-step how to fit a dog with a harness , how to adjust it properly, and how to choose the right model.

Why is it so important to put a harness on your dog correctly?

An ill-fitting harness can hinder your dog's movements, cause friction, and even pain. Conversely, a properly fitted and adjusted harness provides optimal support without restricting their freedom of movement. It's the foundation for a successful walk or a pleasant jog together!

Prepare the harness before first use

Before even putting it on your dog, start by identifying the different parts of the harness :

  • The strap that goes under the chest

  • The one who rests on the back

  • The straps that surround the neckline and chest

Unfasten all buckles to make installation easier. This small step makes putting them on more smoothly, especially if your dog isn't used to it yet.

  • Position the harness : the longer part goes under the chest, while the shorter part rests on the dog's back.

  • Adjust the straps before clipping : do a quick pre-adjustment if necessary, especially if the harness is new.

  • Clip the buckles : generally, you will have one buckle at the neck, and two others on the sides of the chest.

At this stage, the harness is in place, but it still needs to be adjusted correctly.

How to properly adjust a dog harness?

A proper fit is essential for your dog's comfort and safety. Here's how to do it:

  • Neck straps : Adjust them so that you can slip two fingers between the strap and your dog's neck. Too tight = discomfort. Too loose = ineffective.

  • Chest circumference : apply the same two-finger rule.

  • Symmetry : Make sure the settings are the same on both sides for good balance.

Tip : Don't hesitate to walk your dog a few steps to see if the harness stays in place.

How do I check that the harness is properly adjusted?

Here are the signs that everything is ok:

  • The harness does not rotate around the body

  • Your dog can move his shoulders freely

  • No pressure points hinder its movements

  • He doesn't seem irritated or annoyed

On the safety side, check that all clips are holding securely, and gently pull on the leash to test the overall hold.

What if the harness is not adjusted correctly?

Don't panic! If you notice the harness moving, slipping, or bothering your dog:

  • Resume settings

  • Check the size you choose : a harness that is too big or too small will not fit properly, no matter how hard you try.

Removing the harness: how to do it easily?

Two options depending on the model:

  • By the head: by declining the loops of the chest and sliding it forward

  • By the legs: by detaching the side straps and passing it through the front limbs

It's best to test both methods to see which is more comfortable for your dog.

What size harness should you choose for your dog?

Take the following steps:

  • Chest circumference (just behind the front legs)

  • Neck circumference (at the base of the neck, not at the usual collar level)

At aventurecanine, all our size guides are displayed in photos for your convenience! Refer to this guide and, if your dog is between two sizes, generally choose the larger one (it's better to adjust rather than compress).

Dog collar

Harness or collar: which to choose?

It all depends on the use:

  • For quiet walks , a collar may be sufficient.

  • For active walks, dogs that pull, or sporting activities (such as running with your dog ), a harness is highly recommended.

  • If you do traction (canicross, cani-rando), choose a specific harness adapted to this practice , designed to absorb the forces while preserving the comfort of your companion.

Tip : Having a collar + a harness allows you to vary depending on the situation.

Remember to check the settings regularly

The harness may move over time due to:

  • repeated pull-ups

  • weight changes

  • hair that thickens or thins depending on the season

Do a quick check before every outing: it only takes a few seconds and can avoid a lot of hassle.

In summary

Putting a harness on your dog isn't just a routine: it's a moment that prepares your duo for a wonderful experience, whether you're walking or running. When properly fitted, adjusted, and chosen, it guarantees comfort, freedom of movement, and safety for your faithful companion.
