I wouldn't put the tags that have the microchip # on them, I only say that because I heard of someone having their dog lost then seen their dog with someone else and is fighting to get it back because the people that found it called the microchip company and had all the info changed into their name somehow so they had to fight it in court, i'm not sure how it turned out but it was on the news. People are now saying if you want to let people know your dog has a microchip then just put a tag on them that states they are microchiped. wow I really hope that made sense. but anyways I know what you mean about so many tags. It's rediculous. Hope I helped
