A modern classic that is both stylish and practical. The durable nylon has reflective thread sewn into it, making the collar glow in the dark. The collar has a fast-opening buckle closure with a safety lock. If the dog is a pulling- type of dog, you can attach the leash to two safety-rings, which are on both sides of the buckle. This takes the pressure away from the buckle and adds safety. The collar can also be used as a semi-slip collar. There is a stylish gunmetal finish on all metal parts. The machine-washable collar dries fast and is easy to keep clean.
