The Chain Reaction Collar is a great solution for dogs who slip out of traditional collars. It’s a martingale-style collar that combines Ruffwear-designed TubeLok webbing with integrated reflectivity and a short section of stainless steel chain. This collar also features a V-ring attachment so you can use it as a standard collar, separate ID tag attachment point, and silicone tag silencer. Try our matching Crag Leash (sold separately) for the complete setup.
