Bitten by an Unvaccinated Dog? What to Do and Your Rights

If you were bitten by an unvaccinated dog, you have two immediate concerns and one longer one. The immediate ones are medical: rabies post-exposure prophylaxis (PEP) and wound infection. The longer concern is legal: the owner failed a duty required by state law to vaccinate their dog, and that failure typically makes your claim stronger.

This guide covers what happens medically after a bite from an unvaccinated dog, how the 10-day quarantine works, why the missing vaccination matters for your case, and what to document.

The Medical Response Comes First

Wash the wound thoroughly with soap and running water for at least 15 minutes, then get to an emergency room the same day. This first-aid guidance is standard across CDC, WHO, and hospital emergency departments. Rabies virus is inactivated by thorough washing, and 15 minutes of soap and water at the scene meaningfully reduces the transmission risk before you get to a hospital.

At the hospital, the treating clinician will decide whether to start rabies post-exposure prophylaxis (PEP) based on: whether the dog is available for observation, whether the dog is vaccinated, and the rabies risk in your area. If any of those points are uncertain, PEP is usually started immediately and stopped later if the dog turns out to be healthy at day 10.

PEP is a series of shots: an initial rabies immune globulin injection (given at the wound site if possible) and a course of four rabies vaccine doses over 14 days. It is highly effective when started promptly.

The 10-Day Observation Rule

Every state requires a biting dog to be quarantined for 10 days for observation, whether or not the dog is vaccinated. This is the single most important test for whether you were actually exposed to rabies.

The reason is biological: a dog capable of transmitting rabies through its saliva will show clinical signs of rabies within days, and will die from the disease within 10 days. If the dog is alive and healthy at day 10, the CDC’s position is that no rabies was transmitted by that bite. PEP can be stopped.

Where the dog is quarantined depends on the situation:

• Vaccinated, cooperative owner: home quarantine, with local animal-control verification.
• Unvaccinated or uncooperative owner: quarantine at a shelter, veterinarian’s office, or another approved facility, usually at the owner’s expense.
• Unavailable or stray: you get the full PEP course. The clinician cannot assume the dog was healthy.

Report the bite to animal control the same day. That report is what triggers the quarantine and starts the clock.

Why the Missing Vaccination Matters Legally

Nearly every state and most municipalities require dog owners to keep their dogs vaccinated against rabies. When a dog owner fails that duty and their dog then bites someone, the failure typically strengthens the victim’s case in three ways.

Negligence per se in states that follow it

Where a statute imposes a duty and someone violates that duty, most states allow a plaintiff to use the violation itself as proof of negligence. This is called negligence per se. A mandatory rabies vaccination law is a public safety statute. A dog owner who ignored it, and whose dog then bit someone, has already breached a statutory duty. In many jurisdictions the plaintiff does not have to separately prove the owner was careless; the statutory violation does that work.

Extra damages for the PEP exposure itself

Even setting aside the bite injury, being exposed to rabies is a compensable harm. The cost of PEP is real (often four to five figures). So is the emotional distress of undergoing rabies exposure treatment. So is the time missed from work for the vaccine series. These are separate damages on top of the underlying bite injury, and they only exist because the dog was not vaccinated.

The owner cannot claim they had no reason to think the dog was dangerous

In one-bite states, the owner’s liability often depends on what they knew or should have known about the dog. An owner who did not bother to get basic vaccinations is not credible on the “we had no idea” argument. The failure to meet the most basic ownership standard cuts against the owner across the whole case, not just on the rabies exposure question.

If the dog that bit you was not vaccinated, do not have this conversation with the owner’s insurance company alone. The failure to vaccinate is one of the strongest cards in a dog bite case, and how it is framed early affects the outcome.

What Happens to the Unvaccinated Dog

An unvaccinated dog that bites a person faces significantly harsher consequences than a vaccinated one. The exact consequences vary by state and county, but they typically include:

• Immediate quarantine, usually at the owner’s expense. Not home quarantine.
• Vaccination on the spot, with an additional booster later in the observation period.
• Possible euthanasia if there is reason to believe the dog was actually exposed to rabies (a wild-animal bite, contact with a known rabid animal).
• Extended strict-observation quarantine of up to four months in some states, in place of euthanasia, if the owner wants to try to keep the dog.
• Fines and civil citations for the vaccination violation itself, separately from the bite.

The CDC’s guidance for unvaccinated dogs exposed to rabies is euthanasia unless the owner accepts the extended strict-observation quarantine. Most local ordinances follow that framework.

Damages You Can Claim

The bite itself is not the only injury when the dog was unvaccinated. Your claim typically covers:

The Documentation Checklist for an Unvaccinated Dog Bite

Documentation for a rabies-exposure case has two extra items on top of the standard bite claim.

1. Get to the emergency room the same day. The medical record must document the bite AND that the dog’s vaccination status was unknown or confirmed unvaccinated at intake.
2. Report the bite to animal control immediately. This triggers the 10-day quarantine and creates the official record of the dog’s vaccination status.
3. Ask the owner for the dog’s rabies vaccination records in writing. An owner who can produce records will produce them. An owner who cannot, or who refuses, is documenting the failure for you.
4. Save every PEP bill and receipt. Immune globulin, each vaccine dose, hospital co-pays, and any pharmacy costs. This is separately compensable.
5. Document all missed work, including the days you took off for each vaccine dose.
6. Keep a short daily journal during the exposure period. The anxiety, sleep disruption, and fear waiting to see if the dog survives quarantine are real damages that are hard to reconstruct later.
7. Photograph the wound the same day and through healing.
8. Get witness names and phone numbers on the spot.
9. Do not give a recorded statement to the owner’s insurer. The rabies exposure and the vaccination failure are two of the strongest angles in the case. How they are framed in the first phone call matters. Free 24/7 consultation: 312-786-4442 or contact form.

Frequently Asked Questions

What happens if an unvaccinated dog bites you?

You need immediate medical care and rabies post-exposure prophylaxis (PEP) unless the dog can be quickly observed for 10 days and confirmed healthy. Wash the wound with soap and running water for 15 minutes, then get to an emergency room the same day. Report the bite to animal control so the 10-day quarantine can begin. Legally, the dog owner’s failure to vaccinate typically strengthens your case: nearly every state requires rabies vaccination, and the violation is often treated as negligence per se.

How likely is it to get rabies from an unvaccinated dog?

In the United States, transmission from an unvaccinated pet dog is rare, but PEP is still standard until the dog is confirmed healthy after the 10-day observation. Human rabies deaths from dog bites in the U.S. have been very rare for decades because PEP is highly effective when started promptly. The risk depends on whether the dog itself had been exposed to a rabid animal (typically a bat, raccoon, skunk, or fox). The 10-day quarantine settles the question: a dog alive and healthy at day 10 did not have rabies at the time of the bite.

Should I be worried if a vaccinated dog bites me?

Rabies risk from a properly vaccinated dog is very low, but you still need medical care for the wound itself, and the biting dog is still quarantined for 10 days as a matter of standard practice. Wound infection is the real concern with any dog bite, vaccinated or not. Puncture wounds seed deep bacterial infections and are often treated with prophylactic antibiotics regardless of the dog’s vaccination status. Our guide to dog bite infection warning signs covers what to watch for.

What is the 10-day rule for rabies?

Any dog that bites a person is quarantined for 10 days for observation, regardless of vaccination status, because a dog capable of transmitting rabies at the time of the bite will show clinical signs and die within 10 days. If the dog is alive and healthy at day 10, no rabies was transmitted by that bite, and PEP can be stopped. This is the definitive test. Quarantine happens at home (for vaccinated dogs with cooperative owners) or at a shelter or veterinary facility (for unvaccinated dogs or uncooperative owners), typically at the owner’s expense.

How late is too late for rabies shots?

Start rabies post-exposure prophylaxis as soon as possible after the bite, ideally within 24 hours, but PEP has been effective when started days after exposure and should still be given even if some time has passed. The critical window is before symptoms appear; once rabies symptoms develop, the disease is nearly always fatal. If you were bitten days ago and never sought treatment, do not conclude it is too late. Go to a hospital and let a clinician assess the risk.

Can I sue for the cost of rabies shots?

Yes, the cost of PEP is a compensable damage in a dog bite claim, especially where the dog was unvaccinated. PEP often runs into thousands of dollars per patient, sometimes higher. The dog owner’s homeowners or renters insurance policy typically covers dog bite liability, including the PEP cost. When the dog was unvaccinated in violation of state or local law, that violation strengthens the case and the emotional distress of the rabies exposure workup is a separate line of damages on top of the physical injury.
