All of our collars and leads are handcrafted in the U.S.A. with the highest quality materials. Our cotton fabric cover helps keep pet fur from matting. The high-tensile strength webbing forms a strong inner core for both the collars and leads. Our heavy-duty buckles and slide make the collars fully adjustable. The thick, metal D-rings on the collars and heavy-duty bolt snap-locks on the leads ensure a secure collar-lead connection. What's more, our products are super easy to clean. Simply treat your collars with a stain remover (such as Spray 'n Wash®), hand or machine wash in cold water, and line or machine dry. You can keep items clean between washings by treating them with a fabric protector.
