Rogz Control Collar, Chain, Utility is a safe, non-slip collar recommended for behaviour correction and training. The sound and vibration from the rust-proof stainless steel chain, together with gentle pressure applied via the lead, aid 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. Accessory D ring for ID tag attachment.
