All animals receiving rabies vaccinations are issued a rabies tag that has been purchased from Cook County Animal and Rabies Control. These tags act as proof of rabies vaccination as well as a form of identification. Each tag is entered into a database maintained by Cook County Animal and Rabies Control. It allows for the reunion of lost pets with their owners. The current database utilized by Cook County Animal and Rabies Control is the second largest in the country with more than 500,000 registered animals.
Cook County residents can purchase replacement tags if the tag is lost or if the resident moved from another location. This process is only for pet owners that have a current vaccination certificate from a veterinarian. To register your pet with Cook County, please mail a copy of the following documents:
State issued identification
Utility bill or first page of current lease
Please include a current phone number and the pet's name. The cost of the replacement tag is $6 for a 1 year tag and $18 for a 3 year tag. Make check or money order payable to Cook County Animal and Rabies Control. Do not mail cash, residents can come to our office to purchase a replacement tag with the same documents.
