It is an old model or a product that we can no longer order at the manufacturer.
The Ruffwear Knot-a-Collar is discreet to fit comfortably in short or long fur and the sliding fisherman knots make it easy to adjust. The collar's built-in reflectivity enhances your dog's visibility in low light conditions.
The collar is packed with important features such as a separate attachment point for ID tags, a silicone tag silencer, and a strong leash attachment point for a secure connection with your dog on a leash.
