Coastal Pet Products DCP554020 Titan X-Heavy Chain Dog Training Choke/Collar with 4mm Link, 20-inch, Chrome

I've used chain training collars on all my dogs, and these meet my requirements: quality construction, adequate (large) link to avoid pinching, and hair pulling/loss, and a reasonable price. When used properly there's no better way to keep your dog's attention when training, or to maintain control of a dog that wants to walk ahead of, or lag behind its owner. The accompanying photograph of the Doberman Pinscher wearing the collar is incorrect! The part of the chain that slides through the loop should always lay on the back of the dog's neck!! Using the collar as illustrated could result in injury to the dog's throat/airway, or even death. One last caution: Do not use this training collar as your dog's "everyday" collar. It should only be used when you are physically connected to your dog with a leash.

The 4mm chain is well made and each link is welded closed, not just squeezed shut. I really like the 4mm size as it spreads the force of pulling on the leash instead of acting as a garrote like smaller chains. My Dobie snapped two of the smaller chains but I don't believe he can snap this one.

The choker was heavy duty just what I needed for my K-9

Delivered Sunday today is Tuesday and already falling apart

Not much to say about this piece. It works as its intended for and to my knowledge, it hasn't tarnished. Very sturdy and I'm sure our dog wont break through this or anything of that matter any time soon. Its a bit big for our German Shepherd but ehhh still works and he'll grow more into it since hes 6 months.
