The Ancol Heritage Nylon & Chain Check Collar combines durable nylon and sturdy welded chain to make a combination collar with check-chain properties. Nylon is an excellent material for both collars and leads as it is strong, lightweight and weatherproof; this allows your dog to get out and about in rain and shine. Features plastic adjuster buckles for a snug fit and a satin-finish buckle and D-ring for simple lead attachment.
