Step 1: Get Medical Attention Immediately

The first thing you need to do after a dog bite is seek medical care, even if the wound looks minor. According to the CDC, up to 20% of dog bite wounds become infected. Bacteria from a dog’s mouth can enter deep into tissue fast. Infections like cellulitis, tetanus, and rabies exposure are all real risks that need to be ruled out by a doctor.

Go to an emergency room, urgent care clinic, or your primary care doctor as soon as possible. If the bite is on your face, hands, or near a joint, treat it as urgent. Doctors will clean the wound, assess the damage, and determine whether you need stitches, antibiotics, or a rabies evaluation. Bites to the hands or fingers can cause nerve damage, tendon injuries, or crush damage that are not always obvious right away.

Here is something many people do not realize: under Section 18 of the Illinois Animal Control Act (510 ILCS 5/18), any physician or other medical personnel who provides treatment for a dog bite must report the incident to the local animal control program within 24 hours. So your doctor is legally required to file a report. That report becomes part of the official record, which matters if you later pursue a claim.

Keep every document from your medical visit. Ask for copies of your treatment notes, the bite report, and any prescriptions. These records are the foundation of your personal injury case. Future medical costs, including follow-up care, physical therapy, or psychological treatment for trauma, are all part of the damages you may be able to recover. Do not minimize your injuries or skip follow-up appointments. Every visit creates a paper trail that tells the story of how seriously you were hurt.

Step 2: Report the Bite to Chicago Animal Control

Reporting the bite is not optional in Illinois. In Chicago, all dog bites must be reported to Chicago Animal Care and Control (CACC) or the Cook County Department of Animal and Rabies Control, depending on where the bite occurred. Reporting ensures that the dog’s rabies vaccination status is verified, the animal is properly quarantined or observed, and that victims can prove the incident for any potential legal claim.

You can file a bite report by calling 311 or visiting 311.chicago.gov to submit a report under “Animals,” and you should provide details including where the bite occurred, the dog owner’s name and address if known, the location of the attack, and a description of the dog. If the attack happened outside city limits, bites to humans must be reported to local police or to the Cook County Sheriff’s Office for unincorporated areas, and a Cook County Bite Report will be completed by the law enforcement agency and forwarded to the Department of Animal and Rabies Control.

This report does more than trigger a public health response. It creates an official record of the incident, which is critical evidence if you file a personal injury claim. Insurance companies and defense attorneys will look for holes in your story. A police or animal control report filed close in time to the attack is one of the strongest pieces of documentation you can have. It shows when the bite happened, where it happened, and who was involved. Cases involving leash law violations or a dog with prior complaints to animal control are often strengthened significantly by this early report.

Under 510 ILCS 5/13, the owner of a biting animal must also remit a $25 public safety fine to be deposited into the county animal control fund. That fine is separate from any civil liability the owner faces toward you.

Step 3: The Dog Is Quarantined and Observed

Once the bite is reported, Illinois law kicks in immediately for the dog. When a state health administrator receives information that any person has been bitten by an animal, the administrator shall have the dog confined under the observation of a licensed veterinarian for a period of not less than 10 days from the date the bite occurred. This quarantine period is a public health requirement, not a punishment, and it exists to determine whether the dog was carrying rabies at the time of the attack.

The owner, or if the owner is unavailable, an agent or caretaker of an animal documented to have bitten a person, must present the animal to a licensed veterinarian within 24 hours. At the end of the confinement period, the animal must be examined by a licensed veterinarian, inoculated against rabies if eligible, and microchipped if the dog has not been already, at the expense of the owner. The owner pays for all of this.

Why does this matter to you as a victim? If the dog shows no signs of rabies during the 10-day observation period, your doctor can make informed decisions about whether you need rabies post-exposure treatment, which is a painful and expensive series of shots. The quarantine protects your health directly. It also creates a veterinary record that documents the dog’s condition, vaccination history, and behavior, all of which can be used as evidence in your case.

It is unlawful for the dog owner to conceal the dog, sell it, give it away, or have it euthanized while it is under observation. Violating these rules is a serious offense. It is unlawful for the owner of the animal to refuse or fail to immediately comply with the instructions made by the Administrator or the Deputy Administrator or their authorized representative. Owners who do not comply face criminal penalties.

Step 4: Understand Illinois Animal Control Act and Your Rights

Illinois provides strong protection for dog bite victims under the Illinois Animal Control Act. Under 510 ILCS 5/16, if a dog attacks, attempts to attack, or injures any person who is peaceably conducting themselves in any place where they may lawfully be, the owner is liable in civil damages for the full amount of the injury. You do not need to prove the owner was careless or that the dog had bitten before, although defenses like provocation and assumption of risk may still apply.

As a Chicago personal injury lawyer would explain, this legal standard is a significant advantage. Unlike states that require proof of negligence or a prior history of aggressive behavior (often referred to as the “one-bite rule”), Illinois law holds owners liable for injuries caused by their dogs under specific circumstances, even if the dog has never shown signs of aggression before. That means a dog that has always been described as gentle can still trigger liability the first time it bites.

To bring a successful claim under 510 ILCS 5/16, you need to show four things: the dog attacked or injured you, you were in a place you had a legal right to be, you did not provoke the dog, and the defendant qualifies as the owner under the law. Under Illinois law, “owner” means any person having a right of property in an animal, or who keeps or harbors an animal, or who has it in their care, or acts as its custodian, or who knowingly permits a dog to remain on any premises occupied by them. That definition is broad. A dog sitter, a neighbor watching the dog for the weekend, or a landlord who allowed a dangerous dog to stay on the property may all qualify.

If a dog is formally classified as dangerous or vicious after an investigation under 510 ILCS 5/15, that designation can strengthen your civil case. Under that statute, a complaint may be filed in circuit court, and the petitioner must prove the dog is vicious by clear and convincing evidence. A working knowledge of how the dog was classified, and whether the owner had prior complaints on record, can significantly affect the outcome of your claim. A dog bite lawyer in Chicago can review the animal control records and use that information to build your case.

Step 5: Document Everything and Preserve Evidence

Evidence fades fast. Wounds heal. Witnesses forget details. The steps you take in the days immediately following a dog bite can make or break your claim. Start documenting from the moment you are able to do so safely.

Photograph your injuries from multiple angles, and keep photographing them as they heal or worsen. Take pictures of the location where the bite happened, whether that is a sidewalk on the North Side, a hallway in a Logan Square apartment building, or a yard in Bridgeport. Capture any torn clothing, broken skin, or visible blood. If there is surveillance footage nearby, such as a doorbell camera or a business security camera, act quickly. Footage is often overwritten within days.

Get the dog owner’s name, address, and phone number. Ask for proof of the dog’s rabies vaccination. Collect the names and contact information of anyone who witnessed the attack. Write down your own account of what happened while the details are fresh. Note the time of day, the weather, what you were doing, and how the dog approached you. These details matter when liability is disputed.

Save every piece of paper connected to the incident. Medical bills, prescription receipts, animal control reports, police reports, and any correspondence with the dog owner or their insurance company should all be kept in one place. If you miss work because of your injuries, document that too. Lost wages are a recoverable damage under Illinois law, as are future earnings if your injuries affect your ability to work long-term. An experienced dog bite lawyer can help you identify every category of damages you are entitled to pursue.

Step 6: File Your Claim and Work Toward a Resolution

After your injuries are documented and the investigation is underway, it is time to pursue compensation. Most dog bite claims in Chicago are filed against the dog owner’s homeowners or renters insurance policy. Many dog bite claims are filed with the at-fault party’s homeowners insurance policy, but insurance adjusters are accustomed to offering low settlements and using delay tactics to minimize what victims receive. Do not accept an early settlement offer before you fully understand the extent of your injuries and future medical needs.

Illinois law allows you to recover compensation for medical bills, lost wages, pain and suffering, emotional distress, and future treatment costs. Cases involving serious injuries, such as nerve damage, permanent scarring, or psychological trauma like PTSD, typically involve larger claims and more resistance from insurance companies. Comparative fault under 735 ILCS 5/2-1116 is also a factor to be aware of. If an insurer argues that you provoked the dog or were partially at fault, your recovery could be reduced. If you are found to be 51% or more at fault, you recover nothing under Illinois law.

The statute of limitations for personal injury claims in Illinois is generally two years from the date of the injury. Missing that deadline means losing your right to sue. Do not wait. Consulting a dog bite attorney early in the process gives you the best chance of building a strong case, meeting all deadlines, and recovering the full compensation you deserve. If the claim cannot be resolved through negotiation, your attorney can file a lawsuit in the Circuit Court of Cook County, where the Daley Center in the Loop handles civil matters for Chicago residents.

FAQs About What Happens After a Dog Bite in Chicago

How long do I have to file a dog bite lawsuit in Chicago?

In Illinois, the statute of limitations for personal injury claims, including dog bites, is generally two years from the date of the injury. If you miss this deadline, you lose the right to sue, regardless of how strong your case is. There are limited exceptions, such as for minor victims, but you should never assume an exception applies. Contact an attorney as soon as possible after the bite to protect your rights.

Does the dog have to have bitten someone before for the owner to be liable in Illinois?

No. Illinois follows a liability rule under 510 ILCS 5/16 of the Illinois Animal Control Act, which means the owner is responsible for the full amount of your injuries even if the dog has never shown aggression before and has no prior bite history. You do not need to prove the owner knew the dog was dangerous. However, defenses like provocation and assumption of risk may still apply to reduce or eliminate the owner’s liability.

What if the dog owner does not have insurance?

If the dog owner has no homeowners or renters insurance, you may still have options. The owner can be held personally liable for your damages, and depending on where the attack happened, a landlord or property manager may also share responsibility. In some cases, third-party liability claims are possible. An attorney can investigate all potential sources of recovery and advise you on the best path forward given the specific facts of your case.

Can I still recover compensation if I was bitten on private property?

Yes, as long as you were lawfully on the property when the bite occurred. Under 510 ILCS 5/16, the liability standard applies whether you were on public property or on private property with the owner’s permission. If you were a guest, a delivery worker, a utility worker, or a tenant in a common area, you were likely in a place you had a legal right to be. Trespassers generally cannot bring a claim under this statute, though other legal theories may still apply.

What should I do if the dog owner tries to claim I provoked the dog?

Provocation is one of the defenses that can reduce or eliminate a dog owner’s liability under Illinois law. If the owner or their insurance company makes this claim, your evidence becomes critical. Witness statements, surveillance footage, your own written account, and the circumstances of the attack all help counter a provocation defense. Do not discuss the details of the attack with the owner’s insurance adjuster without legal counsel. Contact Briskman Briskman & Greenberg to discuss your case before making any statements that could be used against you.
