For the safety and comfort of your dog it is essential to measure your dog accurately to ensure harnesses are fitted correctly. The harness should be snug but not too tight. A wrong sized harness, or an incorrectly fitted harness, can cause injury and discomfort to your dog.

For more a more detailed guide on how to measure your dog and how to correctly measure and put on Julius-K9® harnesses see below.

 

Measuring Your Dog

You will need to measure you dog’s chest circumference to know which size of harness you need.

Step 1) Pace four fingers behind the dog’s front legs for harnesses sized 0 to 4, and two fingers for harnesses sized Baby 1 and Baby 2. Roughly for small dogs there should be 1 inch behind front leg and for medium and large dogs there shoulld be 2 inches.

Step 2) The finger furthest away from the front legs is where you will be measuring the circumference of the dog’s chest.

Step 3) Use a fabric tape measure to wrap around the dog’s chest. The tape measure should be snug, without being too tight or baggy.

Step 4) The dog’s chest size is where the end of the tape measure and the remaining portion meet.

 

Fitting The Harness

The harness should be snug, but not too tight. There are three checks to do that make sure the harness is fitted correctly. An incorrectly fitted harness can cause discomfort and injury

Check 1 - Tightness

A well fitted harness should l allow enough room for you to fit your fingers between the dog’s back and the harness.

Check 2 – Bottom Strap Location

The bottom belly strap should be four fingers width  away from the front legs for harnesses sized 0 to 4, and two fingers for harnesses sized Baby 1 and Baby 2.

Check 3 – Top Strap Location

The front chest strap should fit comfortably against the chest without drooping toward the legs or riding up toward the neck.

Low Front Strap: If the harness is too small (above image), the front strap will sit too high and put pressure on the dog’s neck.

High Front Strap: If the harness is too big (above image), the strap will drop too low and not distribute pressure to the chest area as intended.

The dog can also back out or escape from the harness if the front strap is too high or low.  

 

Adjusting The Harness To Fit Correctly

The video below shows how to easily tighten and adjust the harness correctly:

Tightening & Losing The Strap

how to adjust the harness strap

Step 1) Open the strap and loop it through the oval ring on the front of the harness.

Step 2) Close the strap on the inner side so the hook loops are facing each other.

Step 3) Set between the Max. and Min. adjustable size (image above).

How Tight Should A Harness Be?

The harness should fit snugly on the chest area. You should be able to fit two fingers between the harness and the dog.

If the strap is too loose, the dog can slip out of the harness. An overly tight strap will mean the harness is uncomfortable and may cause chafing.

 

Securing The Handle

how to secure the handle

The harness handle on the IDC® Powerharness has 4 different fastening options. It is possible to secure only the INOX® ring or only the handle, or both, or neither.

Handles on IDC® harnesses (sizes Mini and Mini-Mini) can be secured/ covered up with hook & loop fastener.

These fastening options minimise the risk of the dog getting caught on something by the handle. This is especially important when the dog is off-lead and is running free.

 

What If The Dog’s Tries To Back Out Of Harness?

what to do if the dog backs out of harness

In case your dog attempts to slip out of the harness by backing out of it, or tries to pull its head out of the collar, avoid pulling the leash.
