Frederick County offers a Lifetime Dog Tag. This tag will be valid for the life of the dog if it remains with the same owner and rabies vaccination information is kept current.
To purchase a dog tag, you will need the rabies vaccination information. If you have received a notice from our office, your veterinarian has provided that information to us and you can simply look up your dog by ticket number.
