Please Note: We strongly advocate the proper fitting and use of prong collars. We recommend placing prong collars LOW on the dog’s neck, representing the dog’s Play Bite area, closest to the dog’s shoulders. Please see the attached photos. While many professional trainers and organizations insist that prong collars be placed HIGH and tight on the dog’s neck (Kill Bite Area), we strongly advocate against this placement. To ensure playful, happy training experiences, we strongly recommend using prong collars in a playful dog way. To learn more about how to measure your dog’s neck, click here.
