How to Measure Your Dog for a Harness: 3 Easy Steps

When it comes to choosing the perfect harness for your dog, accurate measurements are crucial. A well-fitted harness ensures your dog’s comfort and safety. Follow these three easy steps to measure your dog and find the perfect harness.


Why Measuring is Important:


Dog sizes can vary significantly even with the same weight. For instance, a 40-pound dog might be slim and lanky or broad and stocky. Accurate body measurements ensure you select a harness that fits perfectly, providing comfort and security for your dog. A poorly fitted harness can harm your dog and restrict its movement. Let's get started!

Step 1: Measure the Chest Girth

The chest girth is the most important measurement for a dog harness. It’s the widest part of your dog’s ribcage, just behind the front legs.

  1. Get a flexible measuring tape or a piece of string you can measure later.
  2. Wrap the tape around your dog’s chest at the widest point.
  3. Record the measurement in inches or centimeters.

Pro Tip: Make sure the tape is snug but not too tight. You should be able to fit two fingers between the tape and your dog’s body.


Step 2: Measure the Neck Girth

The neck girth measurement ensures the harness will be comfortable around your dog’s neck.

  1. Wrap the measuring tape around the base of your dog’s neck, where the collar usually sits.
  2. Record the measurement in inches or centimeters.

Pro Tip: Some harnesses have adjustable neck straps. If your chosen harness does, you may have a little more flexibility with this measurement.


Step 3: Measure the Length (Optional)

While not always necessary, measuring your dog’s length can help with finding a better fit for certain harness styles.

  1. Measure from the base of your dog’s neck (where the neck meets the shoulders) to the base of the tail.
  2. Record the measurement in inches or centimeters.

Choosing the Right Size

Once you have these measurements, refer to the sizing chart provided by the harness manufacturer. At Wildside Dog Gear, we offer harnesses with four adjustable points to ensure a custom fit for every dog.


Final Tips for Measuring Your Dog:

  • Measure when your dog is calm: An excited dog might give you inaccurate measurements.
  • Double-check your measurements: It’s always a good idea to measure twice to ensure accuracy.
  • Consider your dog’s weight: Sometimes, weight can help determine the best harness size if your dog is between sizes.

Why Proper Fit Matters

A properly fitted harness distributes pressure evenly across your dog’s body, preventing strain on the neck and allowing for better control during walks. It also reduces the risk of your dog slipping out of the harness, ensuring safety and comfort.

Sturdy, Durable, Best Buckles

"We LOVE our wildside dog harness. We have a 55lb dog (wears size large) and we live an active lifestyle. The buckles are study and the front buckle has a lock function so we don't worry about it coming undone. The material is super breathable and you can throw it in the washer when it gets dirty. We have washed multiple times and the color is still perfect. Candi is also very responsive and cares about her customers. We recommend this brand to all of our large breed and outdoorsy friends." - Hanna


Great Harness for My Reactive Dog

"I really enjoy this harness. The handle is really comfortable, and works great when I need to get a more secure grip on my reactive dog when we walk towards other dogs on walks. It fits similarly to our previous harness (Ruffwear Front Range), but I think it is actually even better quality than that one. I also prefer that there is the additional clip on the neck strap, so I don’t have to put my dogs head through the hole in the harness as my dog always hated taking that one off and on because of it (my main issue with our previous Ruffwear). " - Gina


Amazing Products and Great Customer Relations
I have nothing but great things to say. The harness fit both dogs really well and it is hard to find stuff that works well for my odd shaped “hippopotamus” pit bull. - Audrey 

With the right harness, walks can be enjoyable and safe for both you and your dog. Whether you opt for a back-clip, front-clip, or dual-clip harness, prioritize fit and functionality to enhance your daily walks together.

Frequently Asked Questions

Which harness type is best for my dog's pulling behavior?

Front-clip harnesses are ideal for dogs that pull, as they redirect the dog's attention towards the owner, promoting better leash manners. Do remember that a front clip harness will not magically fix the pulling behavior. Consistent training will as the harness will be part of your training tools. 

How do I ensure a proper fit for my dog's harness?

Adjust the harness snugly but comfortably around your dog's body. Check for any signs of discomfort or chafing during use. You can download the Harness Measurement Guide Here: Download Guide 


Can a back-clip harness help with leash training?

Back-clip harnesses are better suited for dogs already trained to walk politely on a leash and are less likely to pull.

What are the benefits of a dual-clip harness?

Dual-clip harnesses offer flexibility, allowing owners to use either the front or back attachment depending on the walking conditions.
