Chicago FAQs
My dog bit a neighbor in Chicago — do I call the city or the county?+
Call Chicago Animal Care and Control first at (312) 747-1406 — they run the bite case within city limits. CACC will loop in the Cook County Department of Animal and Rabies Control if needed. The bite must be reported within 24 hours under Chicago Municipal Code.
I have a Cook County rabies tag but no Chicago city license. Is that enough?+
No. Cook County's rabies tag and Chicago's city dog license are two separate requirements. The Cook County tag is issued at vaccination by your veterinarian; the Chicago license is purchased annually through the City Clerk's office. You need both.
A bat got into our apartment in Wicker Park. What do we do?+
Confine the bat in a closed room — do not release it. Call CACC at (312) 747-1406. If anyone was sleeping in the room where the bat was found, treat it as a possible exposure and go to the nearest ER for PEP evaluation. If the bat can be captured safely, CACC can submit it to IDPH for rabies testing, which may eliminate the need for PEP.
Which downtown Chicago ERs should I call about PEP?+
Northwestern Memorial Hospital (Streeterville), Rush University Medical Center (Near West Side), Stroger Hospital (West Side / public), and University of Chicago Medicine (Hyde Park) are the major downtown-area emergency departments to contact about PEP. Rabies vaccine and HRIG availability is not published reliably and changes often — call before traveling.
Is there a low-cost pet vaccination clinic in Chicago?+
CACC and several partner organizations run periodic low-cost rabies vaccination clinics, typically $5–$10 per pet. Schedules are published on the CACC website. PAWS Chicago and the Anti-Cruelty Society also offer low-cost vaccinations year-round.
