All measurements in cm. Weight in kg.
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. Weight is a secondary guide only; choose by measurements rather than breed.
