Darwin and Mabel have their rabies, microchip and personal id tags on them all of the time except for bath. IMO all of these tags will help bring my pups home quicker. I don't worry so much about them getting caught on fences as they are always supervised and the collars are properly sized to their necks. Each to their own, but I think ID tags are great - Mabel is also tattooed just to help a bit more!
