Measure Once — That's It:
1. Wrap a soft tape around the widest part of the chest, just behind the front legs.
2. Snug, not tight — two fingers should fit under the tape.
3. Match the cm number to the chart below (our harnesses are cut to cm specs).
Between Two Sizes?
Ranges overlap on purpose. Size up for barrel-chested breeds & growing puppies, size down for lean, narrow builds. Wrong fit? Free size exchange — we've got you.
Chest under 38 cm? That's smaller than our smallest size — message us before ordering and we'll help.
