Our Size Guides

Getting the right fit is crucial for your dog's comfort and safety, especially for powerful breeds. This guide shows you how to measure your dog's neck and chest accurately and choose the right size harness or collar.

Collar Size Guide

Measure around the base of your dog's neck where the collar will naturally sit. The tape should be snug but not tight. Choose the size that best matches your dog's neck measurement.

Small: 39–51 cm
Medium: 43–58 cm
Large: 48–66 cm

Harness Size Guide

Measure around the widest part of your dog's chest, just behind the front legs.

For the lower neck measurement, measure around the base of the neck and front of the chest. Position the tape just behind the elbow joint of one front let, bring it around the front of the chest at the base of the neck, and continue to just behind the elbow joint of the opposite front leg, following the area shown in the diagram.

Choose the size that best matches both the lower neck and chest measurements. If your dog falls between two sizes, choose the smaller size for a narrower build or the larger size for a broader build.


XS: lower neck 35–43 cm/ chest 48–58 cm
S: lower neck 38–50 cm/ chest 55–65 cm
M: lower neck 42–60 cm/ chest 60–75 cm
L: lower neck 46–67 cm/ chest 66–87 cm
