Does your dog have a habit of roaming the woods, streets, or backyard at night? Keep a watchful eye on them with Glowdoggie LED Dog Collars ($50-$65). These completely waterproof collars use Superflux-LEDs — with 17-year LED life — to make themselves visible at a distance, keeping your pooch visible to both you and any oncoming traffic.
