How to measure your dog

Before checking our dog harness size chart by breed, it’s important to take a few quick measurements to make sure you get the perfect fit. Every dog is built a little differently — even within the same breed — so using a soft tape measure will give you the most accurate results. Measure around your dog’s neck and chest (just behind the front legs) to find the right harness size. Use the guide below to see exactly where to measure before picking your pup’s new harness.

Once you’ve measured your dog, use our size chart below to match their measurements to the correct harness size. The guide above we listed popular breeds to make it even easier to find your pup’s perfect fit — but remember, every dog is unique! So the best thing is to check your measurements against the charts below, we have different style harnesses, but have included our most popular harness style below, the tactical harness and the step-in adjustable. If your puppy is too small for the XXS in either if these styles then try our XXXS harness. If your dog is between sizes, we recommend choosing the larger size for comfort and adjustability.
