Our Reflective Waterproof dog collar is incredible — smell proof, waterproof, reflective (incredibly safe for night walks!) and is one tough dog collar. Besides all that, it looks dang good! Keeping your pup safe is a big job, especially at night. With our Reflective Waterproof Dog Collar, your dog will be seen at night. Our biothane reflective dog collar looks gray in the day but gives a brilliant reflective notice to approaching vehicles.
