A chrome-plated prong training collar from Guardian Gear. It's a classic tool for strong pullers, used by a lot of trainers for leash work with large dogs.
Choose by neck size: 18, 20 or 22 inches
Chrome-plated steel links with a center ring for the leash
Fit it snug and high on the neck, never loose around the base. If you haven't used a prong collar before, ask a trainer to show you how to fit and use it, and take it off when your dog isn't on leash.
