2/27/22 FULL 12/27/21 Great update notification! Now, please add system for deceased pets. We don't wish to delete our dear poodle & transferred his new tag to the Yorkie. Maybe something like the AKC RE unite? Thanks again ! 10/26 Update, again, no notification but battery notification is at least daily. Hope both are bug fixes. Sept: Won't auto update; not clear when batteries are failing. Just replace batteries every three months to avoid lengthy problem solving. Check for updates then, also!
