Our Tilden waterproof collection is made with OllyDog’s AquaGuard, a protective and durable coating that shields against the elements. Say goodbye to unwanted, wet dog smell, for AquaGuard holds anti-odor and anti-bacterial properties to leave the smell of the outdoors… outdoors. Cleaning is made easy- use a gentle, dog-friendly soap and cloth, and requires no down-time to dry. If your dog’s skin gets easily irritated, don’t worry! Because the Tilden wicks away moisture, their neck won’t chafe after wearing the Tilden after a swim. So let your dog get wet- their collar will stay dry!
