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.

The chain turned my dogs' fur black. I am buying different collars somewhere else for that reason. They were ok other than that.

Very good collar.

This collar works great with my lab/cattle dog. Once adjusted, it is easy to put on and take off quickly. My dog is good but can be highly reactive in certain situations. This collar gives me the control I need in those reactive situations.

collar this!

So far so good. My dog is in between sizes and I had to swap it for a small. It keeps my pup in line!

An effective control collar

Our high-energy Aussie has a tendency to pull while out on walks wearing a harness. We decided try this collar and WHAT. A. DIFFERENCE!! Within a few days, she learned that pulling is not what she wants to feel if she suddenly sees... SQUIRREL!! Walks are so much more relaxed now. It's an effective behavior correction collar without harming our sensitive dog. She doesn't even mind putting on the collar (She wears it only for walk-time) . Purchased the collar with the matching Slackline Leash. Great pair! Highly recommend!

Chain Reaction Not Fool-Proof

I purchased for my two big dogs. My pitbull/lab constantly slipped out of it, so I returned. My golden retriever uses it now, but can still pull out of it.
