Illinois Dog Bite Laws
Created by FindLaw's team of legal writers and editors | Last updated April 29, 2019
Although it can be unexpected when a pet dog bites someone, it does happen and can cause serious injuries. Some states impose liability on a dog owner if the dog has previously bitten someone or has been declared dangerous, essentially making dog owners liable if they knew or should have known the animal had "vicious propensities." Other states, such as Illinois, always hold dog owners strictly liable for injuries caused by their dog.
In legal terms, "strictly liable" basically means that the plaintiff doesn't have to prove any negligence on the defendant's part. In contrast, suing someone for negligence requires the plaintiff to prove that a defendant acted in a careless way (like failing to maintain their pet on a leash) which led to the plaintiff's injury.

In the table below, you'll find an overview of dog bite laws in Illinois as well as links to applicable statutes. While reading an overview is very helpful to understand the law better, please remember that it's important to also read the actual statute and to consult with an attorney if you have questions.
| Statute(s) | Illinois Statutes, Chapter 510:
|
| When is a Dog Owner Liable? | If a dog (or other animal) attacks or injures someone who's peacefully conducting themselves in any place they're legally allowed to be, the dog (or animal) owner will be civilly liable for the damages that result from the injuries. Additionally, under Illinois dog bite laws, the owner (or keeper) of a dog is liable for damages caused by their dog chasing, worrying, injuring, or killing someone else's farm animals (i.e. cattle, sheep, goats, etc.) |
| Time Limit for Filing Civil Action | In Illinois, the statute of limitations to file a personal injury claim - including injuries from a dog bite - is 2 years. |
| Available Defenses | It's a defense from liability if the dog (or other animal) attacked only after being provoked. |
Criminal Charges |
A person who conceals, gives away, sells, euthanizes their dog, or otherwise fails to comply with the Administrator's instructions when instructed to turn over the dog for observation can be convicted of a Class A misdemeanor for a first violation, and a Class 4 felony for any subsequent violations. |
