The legal baseline: what Illinois requires
Under the Illinois Animal Control Act (510 ILCS 5/8) (accessed Aug 26, 2026), all dogs and cats four months of age and older must be vaccinated against rabies by a licensed veterinarian. The vaccination must be administered with a USDA-licensed vaccine, and the owner must keep the vaccination certificate.
Illinois also regulates commercial animal facilities through the Animal Welfare Act (225 ILCS 605/) (accessed Aug 26, 2026), which requires boarding kennels to be licensed by the Illinois Department of Agriculture. Licensed facilities must meet standards for housing, sanitation, veterinary care, and record-keeping.
In Cook County (which includes Chicago), the county's Animal and Rabies Control Ordinance (accessed Aug 26, 2026) adds county-level enforcement, including mandatory rabies tags and additional penalties for unvaccinated animals in group settings.

Canine influenza: Chicago's ground zero
Chicago was the epicenter of the 2015 canine influenza H3N2 outbreak in the United States — the first confirmed cases of this strain on American soil. The outbreak spread to over 1,000 dogs in the Chicago metro area within weeks. That history fundamentally changed how Chicago-area boarding facilities operate.
Virtually every boarding facility in Chicagoland now requires canine influenza vaccination. Most require both the H3N2 and H3N8 strains. The initial two-shot series takes 2–4 weeks, so if you're planning to board for the first time, start the process early. Downstate facilities are less likely to require it, but the trend is moving statewide.
Chicago vs. downstate
Chicago-area facilities generally have the strictest requirements in the state — canine flu, fecal exams, sometimes a health certificate within 10–14 days. Downstate and rural kennels tend to stick closer to the state minimums: rabies, DHPP, bordetella. If you travel across the state, keeping your pet current on everything saves the headache of checking each facility's specific list.
What format do facilities accept?
- A printed vaccination record from your vet
- A digital copy emailed directly from your vet's office
- A PDF or screenshot from a health record app — showing vet name, vaccine dates, and expiration dates
What they usually won't accept: handwritten notes, verbal confirmations, or receipts that don't specify the vaccine type and date.
