All measurements in cm.
Allow for a 1–2 cm measurement variation. Compare your dog's neck measurement with the listed range and check fit before use, including when the loop is tightened. The collar must not restrict breathing. Choose by measurements rather than breed. Chest and back measurements are not used for this collar.
