The Coastal Prong Titan Metal Training Dog Collar in Chrome finish delivers safe and effective training control for extra-large, strong dogs. Interlocking chrome-plated prongs apply gentle, even pressure around the dog’s neck when the leash is pulled, simulating a natural corrective nip without causing injury. This collar provides an efficient way to discourage pulling or misbehavior and has a smooth assembly that can be adjusted by removing or adding prong links for proper fit (use only under supervision). Available in Multiple Sizes
