CHOOSING THE CORRECT SIZE:
Measure your dog's actual neck size where the collar will sit (preferably with a soft tape). Then choose the size range that fits your dog's exact neck measurement. Size is measured from 1st Hole to Last Hole. If your dog's neck size is an in between measurement always go with the larger size. Example 20" neck you should choose (19" - 22.5" Neck" rather then "17" - 20.5" Neck)
