Can I Sue Someone if Their Dog Bites Me in Illinois?

 Posted on September 08, 2026 in Dog Bites

You can often sue someone if their dog bites you in Illinois. State law generally holds dog owners responsible for injuries their pet causes, regardless of whether the dog has bitten anyone before. The purpose of a lawsuit is to ensure that you receive financial compensation for your losses, including the mental and emotional ones. If you’re considering a dog bite injury claim in 2026, our Orland Park personal injury lawyer will work with you every step of the way.

What Does Illinois Law Say About Dog Bite Liability?

Under 510 ILCS 5/16, a dog owner is liable for injuries caused by their dog if the dog acted without provocation and the injured person was peacefully in a place where they had a legal right to be. This means Illinois follows what's often called a "strict liability" standard.

No History of Aggression Required

Many states follow what's known as the "one bite rule," which generally requires showing the owner knew or should have known their dog was dangerous based on prior behavior. Illinois doesn't follow this approach.

You generally don't need to prove the dog had a history of biting or acting aggressively. As long as you were somewhere you had a legal right to be and weren't provoking the dog, the owner can typically be held responsible for your injuries.

What Does "Peaceably Conducting Yourself" Actually Mean?

This phrase "peaceably conducting yourself" generally means you weren't provoking the dog or engaging in behavior that would reasonably cause the dog to react defensively. Examples of peaceable conduct include:

• Walking past a dog

• Visiting someone's home as an invited guest

• Being present in a public space where the dog was allowed

If you were teasing, hitting, or otherwise antagonizing the dog before the bite occurred, this can complicate your claim. In that case, the owner may argue your own actions contributed to causing the incident.

Why Provocation is an Important Part of Dog Bite Cases 

Dog owners facing a liability claim often look for evidence suggesting the injured person did something to provoke the attack, since this can eliminate their responsibility under the Illinois Animal Control Act. This makes documenting exactly what happened before the bite occurred an important part of building a strong claim.

What if a Dog Bite Happens on the Owner's Property?

Illinois law doesn't require the bite to happen in a public place for you to have a valid claim. If you were legally on the owner's property, whether as a guest, a delivery person, or someone conducting legitimate business, you can generally still pursue compensation if their dog bites you.

What Compensation Can You Recover After a Dog Bite?

If your claim is successful, you may be able to recover compensation for several different types of losses. Helpful categories to understand include:

• Medical expenses, including emergency treatment, stitches, and any follow-up care

• Lost wages if your injury kept you from working

• Pain and suffering related to the physical injury and emotional trauma

• Scarring or disfigurement compensation if the bite left lasting marks

Dog bites can sometimes cause serious injuries that require extensive medical care. If you suffered injuries that require long-term care, talk to your attorney about it. You may be able to claim future medical costs if ongoing treatment or reconstructive surgery is needed.

How Long Do You Have to File a Dog Bite Claim in Illinois?

Illinois generally requires personal injury claims to be filed within two years of the date of the incident. Missing this deadline can mean losing your right to pursue compensation entirely, even in cases involving clear liability under the dog bite statute.
