The tag indicates that the pet may have a microchip. I have the same type tags for my pets and they were all microchiped. Take it to DCVet or Animal shelter and they can tell you within seconds if the dog has a microchip and even locate the owner for you.
You can also register the dog on Dog Detective Dog DetectiveŽ - Lost Dogs & Found Dogs
