No more water-logged dog collars Your dog loves to play in the rain but you hate the mess and the smell that it leaves in his collar. The Dogline Translucent Reflective Waterproof Collar gives your dog the freedom to splash with wild abandon because it stays dry and odor-free, even when subjected to swampy or brackish waters. Made from Biothane, water rolls right off of it, taking smells with it. Simply wipe this collar clean with a damp cloth to return it to pristine condition. Because Biothane is stronger than other collar materials, the Dogline Waterproof Dog Collar provides greater flexibility and durability. Designed for easy care and reliability A waterproof coating enhances the polyester webbing substrate of our waterproof dog collar, creating a 500-lb break strength per quarter-inch of width.
