All measurements in cm.
Measure the neck around the middle, chest at the widest point behind the front legs, and back from the base of the neck to the base of the tail. Measure with your dog standing. Compare all three measurements rather than choosing by size label alone. Check that the neck section and body band allow comfortable breathing and movement. Keep the nose and mouth uncovered.
