Julius K9 Size Guide

Selecting the right Julius K9 Harness size protects your dog’s neck and shoulders against injuries and ensures optimal freedom of movement. To ensure you select the right harness size for your dog, it is essential to correctly measure the circumference (girth) of your dog’s chest. To do this, locate the position where the strap should go on your dog by:

movement. To ensure you select the right harness size for your dog, it is essential to correctly measure the circumference (girth) of your dog’s chest. To do this, locate the position where the strap should go on your dog by:

Placing 4 fingers (for sizes 0 to 4) behind your dog’s front legs, or
Placing 2 fingers (for Baby1 & Baby2 sizes) behind your dog’s front legs

Having determined the correct position for the strap in this fashion, measure the girth of your dog’s chest at the point immediately adjacent to the finger that is furthest away from his legs (see Image 1).

Once you have this measurement, refer to the size chart below to choose the correct size of harness.

Before putting the harness on, it is imperative to correctly adjust both the chest and lower (under the chest) straps, because:

Straps that are too loose may allow your dog to slip/back out of the harness
A lower strap that is too tight is uncomfortable for your dog
A chest strap that is too tight may cause chafing by rubbing against the skin in your dog’s armpit area

To adjust the chest strap:

Open the strap
Loop the strap through the oblong ring located at the harness’ front side
Close the strap on the internal side so its hooks & loops face each other

Set between the maximum and minimum length settings (see Image 2), the chest strap has the capacity to support several times your dog’s weight.

The chest strap is correctly adjusted when you can comfortably fit 4 fingers (or 2 fingers for Baby1 and Baby2 sizes) between your dog’s front legs and the harness’ belly strap. The belly strap is adjusted correctly when you can comfortably slide your hand (flat) underneath the harness on your dog’s back (see Image 3).

WARNING! Selecting the wrong harness size, incorrectly adjusting the harness or incorrect collar use may cause the dog to slip out of the harness/collar, as well as potentially causing injury.

A properly adjusted, correctly sized harness should:

Give your dog enough room within the shoulder area
Allow your dog to freely move his legs

A harness that is too small will result in the chest strap putting pressure onto your dog’s neck, as opposed to distributing it over his chest area. This could cause injuries. A harness that is too big may allow your dog to step over its chest strap with his front legs, which may also cause injuries.

Petshop Direct and JULIUS-K9® cannot be held responsible for injuries caused by an incorrectly adjusted harness or incorrect choice of harness size.

Securing the Harness' Handle

The IDC® Powerharness’ handle part offers 4 fastening options and can be secured using the handle only, the INOX® ring only, neither or both.

IDC® (Mini & Mini-Mini sizes) and K9® harness handles can be secured/covered up via hook & loop, which minimises the risk of the handle part (and with it your dog) getting caught on anything. This, of course, is especially important for free-running dogs.
