Before you move: the health certificate
Under the Illinois Animal Control Act (510 ILCS 5/) (accessed Aug 27, 2026), dogs and cats entering Illinois from out-of-state must be accompanied by a Certificate of Veterinary Inspection (CVI). The certificate must be issued by a licensed, USDA-accredited veterinarian in your origin state within 30 days of entering Illinois.
The CVI must include:
- Species, breed, age, sex, and identifying marks or microchip number
- Current rabies vaccination status — date, vaccine brand, and expiration
- A health statement that the animal is free from signs of communicable disease
- Owner's name, origin, and destination in Illinois
If you're moving to Chicago's O'Hare or Midway catchment areas, airlines enforce the CVI independently. Even for a drive from Indiana or Wisconsin, the certificate should travel with you.
Rabies vaccination: Illinois requirements
Illinois requires rabies vaccination for all dogs, cats, and ferrets. The vaccination must be current, administered by a licensed veterinarian, and documented with a certificate bearing the vet's license number, the vaccine brand, lot number, and expiration date. Illinois accepts valid out-of-state certificates as long as they fall within the vaccine's labeled duration.
The Illinois Department of Agriculture and local county health departments track rabies exposure incidents, particularly involving wildlife. Skunks and bats are the primary wildlife vectors in Illinois. The Chicago metro area has recorded bat exposures in residential areas — keep your pet's rabies documentation current regardless of whether they go outdoors.
Chicago city licensing
The Chicago Animal Care and Control (CACC) (accessed Aug 27, 2026) requires dogs and cats to be licensed with the city. A Chicago city tag is separate from any county requirement. New residents must license their pets within 30 days of establishing Chicago residency.
| Pet type / status | Annual city tag fee |
|---|---|
| Altered dog or cat (spayed/neutered) | $5.00/year |
| Unaltered dog or cat | $50.00/year |
Chicago's spay/neuter fee incentive is significant — altering your pet reduces the tag fee by 90%. The tag must be affixed to your pet's collar. Proof of current rabies vaccination is required at time of licensing.
Cook County requirements
If you live in suburban Cook County (outside Chicago city limits), the Cook County Animal and Rabies Control (accessed Aug 27, 2026) requires a separate county rabies tag in addition to any municipal license. Dogs and cats must have a current Cook County rabies tag, obtained by showing proof of vaccination at a participating vet or clinic. The county tag and city tag are two separate requirements for Chicago residents — you may need both.
Suburban municipalities within Cook County (Oak Park, Evanston, Cicero, etc.) may have their own additional licensing requirements on top of the county tag. Check with your specific suburb's village hall.
Illinois breed-neutral legislation
Illinois is notable in the Midwest for prohibiting breed-specific legislation (BSL) at the state level. Under the Illinois Animal Control Act, local governments cannot ban specific breeds of dogs. This is meaningful if you're moving with a breed that faces restrictions in other states. However, individual landlords and housing complexes may still impose breed restrictions — review your lease before signing.
Finding a new vet in Illinois
Chicago has one of the densest veterinary networks in the country, including several 24-hour emergency and specialty hospitals. Suburban and downstate Illinois have good general practice coverage but more limited specialty access.
- Book before you arrive — Chicago practices in Lincoln Park, Wicker Park, and Logan Square often have 2–3 week new-patient waits.
- Verify licenses through the Illinois Department of Financial and Professional Regulation (accessed Aug 27, 2026).
- Request complete records at least two weeks before your move, including specialist notes and any imaging files.
Illinois-specific considerations
- Harsh winters: Chicago winters are no joke. Road salt and ice-melt chemicals are used heavily on sidewalks and streets from November through March. These can irritate and dry out paw pads — and are toxic if licked in quantity. Rinse paws after outdoor walks. Consider pet-safe booties for extended outdoor time.
- Antifreeze awareness: Ethylene glycol (traditional antifreeze) is highly toxic to dogs and cats and is used widely during Illinois winters. Wipe up any garage drips immediately and store antifreeze in sealed containers. Propylene glycol-based alternatives are available and much safer around pets.
- Wind chill: Illinois wind chills can make outdoor time dangerous even for cold-weather breeds. Limit outdoor exposure during wind chill warnings, especially for short-coated dogs, puppies, senior pets, and cats. Talk to your vet about your pet's cold tolerance based on their specific health profile.
- Coyotes: Urban and suburban coyotes are active throughout the Chicago metro. Small dogs and outdoor cats are at risk, particularly at dawn and dusk. Keep small pets on leash and don't let cats roam after dark.
