Fit & Measurements

Size Guide

Classic Collars

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.

Collar sizing explained: 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.

For larger breeds, we have designed a slightly different collar width ratio for L and XL sizes to ensure more security and comfort.

Harnesses

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.
