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.

Highly Recommendable

Great collars! Safety first! Your pooch can’t slip out of it if he freaks at something, but you also can’t hurt him. Much lighter than a choke chain (& less confusing for those who can’t put a choke chain on right) or even a nylon collar. I was surprised!!! I love the strip of reflector too; my dogs & I do a lot of road running! It’s nice to have shiny things. Also, a great tool to teach “pressure/release!” (leash manners)

Excellent collar. Should be perfect for Roscoe!

We purchased this collar for our 18 month old Golden Retriever. As he is not always on a leash, having to corrective capability of the collar will be a great addition and hopefully a good reminder for him when we are required to leash him. Thanks for great products and great customer support!

Bad. Got black all over my dog’s beautiful white chest.

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