To keep your dog safe and comfortable, it’s important to choose the right size collar and harness. Grab a soft measuring tape (or a piece of string and a ruler) and follow these simple steps before you order.
Measure for a Harness – Chest Girth & Neck
Chest girth (most important): Wrap the tape around the widest part of the chest, just behind the front legs. Keep the tape level and snug against the fur.
Neck (for harnesses that sit higher on the chest): Measure around the base of the neck where the front of the harness will sit.
Add 2–3 cm to each measurement so your dog can move, breathe, and play comfortably.
Use both measurements to match your dog to our harness size chart.
Fit tip: You should be able to slide two fingers comfortably between your dog and their collar or harness. If it’s tighter than that, go up a size. If it spins or slips off the shoulders, it’s too loose.
