The Coastal Titan Metal Choke Training Dog Collar is a durable choke-chain style collar made for training and behavior correction. Constructed from 1.5 to 2.5 mm chrome-plated steel links, it provides even pressure around the dog’s neck when the leash is tightened, offering a gentle but firm corrective signal. All Titan chain collars feature welded links for strength and are resistant to rust and tarnish, making them dependable for regular training sessions (not to be used for unattended tie-outs). Available in Multiple Sizes
