Fit & Measurements

Harnesses Size Guide

Please measure around your dog's chest using a tape measure.

For small dogs, measure the chest allowing a little extra space for comfort. For larger breeds, a snug fit is recommended, as the leather will naturally stretch and contour to your dog's chest over time.
