This is a 1 inch wide, adjustable collar with a plastic side release buckle. Buckles are contoured to fit against your dog's neck. The collar features heavy nylon with a tensile strength of 4200lbs. We put extra stitching around the D-ring and buckle for maximum strength. The ribbon is woven, specifically designed not to fade or tear. This is machine washable, though lay flat to dry. Our products are made in the USA, in the homes of skilled artisans. Never in a factory!
