It's always a good idea to put a glow in the dark collar on your dog when you go for an evening walk. People generally only put fluorescent accessories on themselves, but your dog can also be a victim when its not seen in the dark. It's also good to think about getting a glowing dog collar when you go to an unfamiliar area while boating, hiking or camping at places where it might get foggy. You'll always be able to see your dog and have peace of mind.
