Good reminder! And great for helping him get back home. I've definitely encountered this in my neighborhood. If they had a tag on w/at least a phone number, I could have called and they would have been home in a matter of minutes. My dog and cat both are chipped and have tags and I always keep an extra collar w/tag on hand especially for my little feline. I use the quick release collars on her as she likes to slink through the bushes.
