Size Guide

If you need any additional help with sizing, please contact us.

How to measure

Use a soft measuring tape and measure your dog while they are standing. If you do not have a tape, use a piece of string and measure it against a ruler.

Collar neck: measure around the neck where the collar normally sits.
Harness neck: measure around the neck where the harness neck opening will sit.
Chest / girth: measure around the widest part of the chest, just behind the front legs. Keep the tape level and do not pull it tight.

Compare your measurements with the correct chart below. For a harness, both neck and chest measurements need to fall within the size range. Do not choose by breed or your dog’s usual size alone. If you are between sizes or the two measurements suggest different sizes, contact us before ordering.

After adjusting the collar or harness, check that it is secure and comfortable, with room for two fingers beneath the straps. Recheck the fit regularly, especially for growing dogs.
