All measurements in cm.
Allow for 1–2 cm variation. Listed ranges are not stated stretch allowances. Measure neck around middle, chest widest behind front legs and back from base of neck to base of tail, with your dog standing. Compare all three measurements and check movement at neckline and body strap. Choose by measurements rather than breed.
