By state law, and to control rabies, the Northville Township ordinance requires every dog to have a license. Licenses expire on Dec. 31 each year. You can renew your dog license by simply bringing in a current rabies certificate (signed by an accredited veterinarian) with cash or check only to Township Hall. To renew by mail, please send a completed application, a copy of the rabies certificate and a check for the license fee and return postage. You will receive your new license and dog tag in two to three weeks.
