Crafty Dog Design collars and leashes are made of cotton fabric and have a stabilized interior of fusible interfacing. Dog collars are adjustable and have a plastic side-release buckle. Buckles are black, but we offer a white buckle for certain fabrics and only for small, medium and large sizes. All collars have a D-ring for attaching tags. Leashes are 3/4 of an inch wide and just over 4 feet long. Hand washing is recommended. Collars are made when ordered and usually shipped within 2-3 days.
