Village code requires that any dog over the age of six months living in Winnetka must have a Village license and that the appropriate tag be displayed on its collar or harness. Current registration tags must be displayed by January 1 of each year. The license fee for un-spayed female dogs is $15, for all other dogs it is $10. A rabies vaccination certificate must be presented before a license can be issued. View a guide for renewing licenses online.
