The Ruffwear Chain Reaction Collar is a martingale-style collar that combines Ruffwear-designed TubeLok™ webbing and a short section of stainless steel chain. This collar provides limited correction with an audible cue, making it a great training tool. In addition to the chain attachment point, this collar also features a V-ring attachment option for use as a standard collar.

Packed full of Ruffwear’s essential collar features: separate ID tag attachment point with tag silencer, strong and comfortable webbing, and aluminum V-ring. Integrated reflectivity keeps dogs visible in low-light conditions.

Available in four color options. Try our matching Slackline™ Leash for the complete set up.

Great product for training

I bought this for my service dog to help in the training process. His neck is 20 inches and I bought the large, so it ended up being a bit on the bigger side. The noise of the chain getting tighter, still reminds him not to pull, so it's still been effective. It's a really high-quality collar, but if you have a dog that's in between sizes, I would go with the smaller size.

My Favorite Collar

I will admit, I do not keep collars on my dogs at all times. I only use a collar when we are doing things away from home, namely running, hence my preference for a "control" collar. Super craftsmanship, easy to clean (throw it in the wash!), and provides excellent control if my dog pulls. No worries about my dog slipping her collar when a squirrel crosses her path! I wouldn't recommend this, or any martingale collar for that matter, as something you keep on your pet 24/7 for you more responsible pet owners, but for walks/hikes/runs, it provides superb control and safety.

Rosie the Rottie could slip out of her collAr if she did not want to go. Now with the new collar she can’t. The new collar makes it easier to handle her. Love it!
