Sizing & Fitting Your 2025 Ruffwear Web Master Harness

Ruffwear's diverse range of harnesses offer solutions for a variety of purposes - from everyday use for a domestic pet, to lift-and-assist for rescue dogs.

With such a wide range of colours, designs and uses, it's no wonder Ruffwear is one of our best selling brands! However, what makes these harnesses truly stand out is their adjustability, meaning the vast majority of dog breeds will get a great fit.

Getting Accurate Measurements

Ruffwear's sizing charts are 100% accurate and factual. They have high adjustability, so the size ranges are based on the harness size at the loosest and tightest settings.

The most important step to getting the best size for your dog is establishing the girth measurement. You can do this by looping a tape measure just behind the dog's front legs. Please ensure that this is measured at the widest point of your dog's chest.

Once you have this measurement, compare this to the size chart on the next page to establish the likely size. All Ruffwear harnesses have the same size banding. For example, if you measure the girth at 75cm, you can expect a Medium to be the size you should try first.

If your dog is on a sizing border, general advice is to choose the larger of the two sizes, or buying both and returning the harness that doesn't fit for a refund.

For puppies, we advise waiting until the pup is near fully grown before investing in a harness. The best time to buy is when your pup is near the bottom of the sizing bracket.

Familiarising Yourself With Your New Harness

The harness will come adjusted so that it fits on the backing card. This will usually mean that the neck is set quite wide and the girth straps are on a small setting.

If this is your first harness, it is important to familiarise yourself with the webbing straps and how they adjust before attempting the fitting.

 

Adjusting the Straps

Begin by unbuckling both and then finding the webbing tail on each. Please note that these may be tucked away in the pad of the strap. Slide the tail through the pad and all the way out to the other end. Then, work the tail's end to the adjuster, before loosening the strap by sliding the adjuster towards the buckle. You can then pull the buckle to take out the slack created by this process.

Fitting Your Web Master Harness

Step One: Loosen all of the straps

As with all Ruffwear harnesses, we would recommend loosening all of the straps, as detailed above.

 

Step Two: Place the harness over the dog's head

After fully loosening off the harness, guide the dog's right leg through the opening, before buckling up both belly straps, as well as the neck straps. The belly straps can only be adjusted on one side, while the neck straps have a slider each side.

 

Step Three: Tightening the neck strap

Starting with the side that sits near the left paw with a buckle, pull down on the webbing tail and hold onto the slider to adjust, until this is fitted comfortably. If done correctly, you should be able to fit about two fingers between the dog and the strap - snug, but not tight.

On the right side, which does not have a buckle, adjust so that it is even with the left side. 

 

Step Four: Tightening the girth & belly straps

Starting with the girth strap, pull down on the webbing tail and hold onto the slider to adjust, until this is fitted comfortably. If done correctly, you should be able to fit about two fingers between the dog and the strap - snug, but not tight. Then, pull down on the adjuster to take out the slack. You can repeat this step with the girth strap.

Ideally, the belly strap will be positioned just behind the ribcage.

 

Step Five: Ensure your dog is comfortable

Take the time to check the overall fit of the harness, now that everything is adjusted. The harness should be a snug fit, but with enough room to fit one to two fingers between the dog and the straps. Straps that are too loose or tight can cause discomfort to your pooch, so ensuring a good fit is key.
