Rogz Utility Control Collar Chain is safe and non-slip with the sound and vibration from the rust-proof stainless steel chain, together with gentle pressure applied via the lead, aiding in obedience training. D-rings are drawn together to prevent your dog from reversing out of the collar, ensuring you maintain control. Highly reflective stitching provides safe, night-time visibility and there is an accessory D ring for ID-Tag attachment.
