A Dog Name Tag Made By Hand From Brass in England Guaranteed For Ten Years. Even If You Lose It? Yes! We got tired of replacing our dog's name tag every six months or so because - while looking pretty initially - it quickly wore away or just fell off. I wanted something MUCH better, something that would actually do the job of helping Lulu get reunited with us when she inevitably got lost (she chased after dear a lot when younger!) Your Ten Year Tag really is Guaranteed for Ten Years, even if your dog loses it or decides to swap it for food (there are minor Ts&Cs - see website for details).
