All measurements in cm.
Measure neck around the middle, chest widest behind the front legs, and back from base of neck to base of tail, with your dog standing. Compare all measurements. Chest ranges are not stated as stretch allowances. Check comfortable movement through all four leg openings. Choose by measurements rather than breed.
