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.

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.

Size Chest Size (cm) Chest Size (inches)
XXXS 25.9 - 30 10.2 - 11.8
XXS 30 - 34 11.8 - 13.4

L 54.1 - 64.8 21.3 - 25.5

Note: For size XL, the straps are slightly wider (2-3 cm) compared to other sizes (1.5-2 cm) for added comfort and durability.
