What state law in Illinois says about pets — in plain English, with a link to each source.
Leaving an animal unattended in a vehicle under dangerous conditions is an offence in Illinois. Only officials such as police, animal control or firefighters are authorised to break in to rescue an animal; a bystander should call 911 rather than break a window.
Animals covered: Any animal
Penalty: A person convicted of violating this Section is guilty of a Class C misdemeanor. A second or subsequent violation is a Class B misdemeanor.
Illinois requires dogs 4 months and older to be vaccinated against rabies, with a booster within a year; cats are covered by county rules.
What the law says: Every owner of a dog 4 months or more of age shall have each dog inoculated against rabies by a licensed veterinarian. Every dog shall have a second rabies vaccination within one year of the first. Terms of subsequent vaccine administration and duration of immunity must be in compliance with USDA licenses of vaccines used. 510 ILCS 5/8
Medical exemptions: If a licensed veterinarian determines in writing that a rabies inoculation would compromise an animal's health, then the animal shall be exempt from the rabies inoculation requirement, however, the owner is still responsible for the tag fees. 510 ILCS 5/8
Yes — Illinois bans breed-specific rules. Local rules may not be specific to breed, and dogs may not be classed as vicious by breed.
Illinois has a strict liability statute: the owner is liable for injuries the dog causes even if the dog had never shown aggression before. Common defences are provocation and trespassing.
What it covers: Attacks, attempts to attack, or injures any person
Where: Peaceably conducting himself or herself in any place where he or she may lawfully be
Defences: Provocation (and, by implication, trespass since only applies when person is lawfully in a place)
Yes. Illinois lets a court include pets in a domestic-violence protective order (since 2007) — for example by giving the petitioner care of the animal and ordering the abuser not to harm or take it.
This Illinois law allows a court to issue an order of protection if the court finds that petitioner has been abused by a family or household member. It also allows for the protection of animals in domestic violence situations. The court can "[g]rant the petitioner the exclusive care, custody, or control of any animal owned, possessed, leased, kept, or held by either the petitioner or the respondent or a minor child residing in the residence or household of either the petitioner or the respondent and order the respondent to stay away from the animal and forbid the respondent from taking, transferring, encumbering, concealing, harming, or otherwise disposing of the animal."
Yes. Since February 2022 Illinois pet shops may only offer dogs and cats from animal control facilities or shelters.

Yes. Dogs entering Illinois need a Certificate of Veterinary Inspection (health certificate) from a vet, issued within 30 days of entry. Dogs 16 weeks of age and older must be vaccinated against rabies.
As summarised by the AKC (March 2023) — confirm with the state veterinarian before you travel:
Illinois has no statewide dog licensing requirement — counties and cities set their own. Most require a licence with proof of rabies vaccination, so check with your local animal services or clerk.
Under the Illinois Animal Control Act a dog found running at large may be impounded, the owner pays a $25 public safety fine, and a dog caught a second time must be sterilized. Hunting dogs and dogs in dog parks are exempt.
Licenses, pet limits, leash and barking rules are mostly set locally:
