Fit & Measurements

Classic Collars Size Guide

Measure snugly around the middle of your dog's neck with a tape measure, without leaving any extra space. Our collars are true to size, so a snug measurement will ensure the best fit.

How sizing works: each collar size reflects its inner circumference range. For example, a size S (27-32 cm) means the collar’s inner circumference fits necks measured between 27-32 cm. Based on this, you can decide whether you want a looser or tighter fit, as the inner circumference of the collar corresponds to your pet’s neck size.
