When a dog bites someone, the dog is almost always placed under a mandatory 10-day quarantine while animal control investigates. What happens to a dog that bites a person after that depends on how serious the bite was, whether the dog was provoked, and whether it has bitten before. Outcomes range from a return home with a warning, to a formal “dangerous dog” designation with lifelong restrictions, to court-ordered euthanasia in the most severe cases.
The 10-Day Quarantine
Once a bite is reported, the dog goes into observation so officials can rule out rabies. The CDC confirms that a dog, cat, or ferret that remains healthy for 10 days after a bite was not infectious for rabies at the time of the exposure.1CDC. Rabies – Yellow Book That window is the whole point of the quarantine, and it governs where the dog spends it.
A vaccinated dog with a responsible owner is often allowed to quarantine at home under strict confinement rules. An unvaccinated dog, or one considered higher risk, is usually confined at a veterinary clinic or animal shelter instead. Either way, the owner pays. Boarding runs roughly $10 to $50 per day, and once veterinary exams are added, the 10-day total can reach several hundred dollars. Ignoring a quarantine order carries fines, mandatory facility confinement at the owner’s expense, or both.
During this same period, animal control documents the circumstances of the bite: was the dog provoked, was it off-leash, does it have prior incidents on record. That background shapes what comes next.
What Happens to the Dog After Quarantine
If the dog stays healthy through the 10 days, animal control or a court decides its future based on the investigation. There are three realistic outcomes.
Returned Home With a Warning
If the bite was minor, provoked, or a genuine first-time incident, the dog goes back to the owner. The bite is still logged, which matters if anything happens again, but no further restrictions apply. This is the most common result for lower-severity bites.
Declared a Dangerous or Vicious Dog
A more serious result is a formal “dangerous” or “vicious” designation under state or local law. This typically applies when a dog inflicts a serious injury without provocation, or when it has a documented history of aggression. The label carries ongoing requirements the owner has to follow for the rest of the dog’s life. These commonly include:
- A locked, escape-proof enclosure for the dog when it is outdoors on the owner’s property.
- A muzzle and short leash any time the dog leaves that enclosure.
- Visible warning signs posted on the property.
- A special liability insurance policy, often with a minimum of $100,000 in coverage.
- Separate annual registration, with fees that typically run $100 to $200.
Violating any of these conditions can trigger seizure of the dog, fines, or misdemeanor charges against the owner. Some jurisdictions let an owner petition to remove the designation after a stretch of years with no further incidents, but in most places the label stays with the dog for life.
Court-Ordered Euthanasia
Euthanasia is reserved for the worst cases. It is most likely when the dog caused a death or catastrophic injury without provocation, when earlier interventions have already failed to control a documented history of aggression, or when the dog tests positive for rabies. A judge usually makes the call after a hearing where the owner can present evidence. In rabies-positive cases, the outcome is essentially automatic.
Contesting a Dangerous Dog Designation
Owners have the right to challenge a dangerous dog finding, and because the designation reshapes what it means to own the dog, the challenge is worth taking seriously. In most jurisdictions, the process begins with a formal hearing before a local hearing board or court, typically held within five to 10 working days of notice. The owner receives written notice and is allowed to present evidence.
The defenses that tend to succeed cluster in a few areas. Misidentification matters when multiple dogs were present and the owner can argue a different animal was responsible. Provocation is a strong defense, because most dangerous dog statutes exclude bites where the victim was taunting, hitting, or otherwise provoking the dog. Severity matters too, since the legal threshold for “dangerous” generally requires more than a minor scratch or nip.
If the initial hearing goes against the owner, an appeal to a higher court is usually available within a short window, often five days. The appeal court typically conducts a fresh review of the evidence rather than just checking for procedural errors, and its decision is usually final.
If the Dog Tests Positive for Rabies
If the dog shows rabies symptoms during the quarantine, or dies and later tests positive, the situation changes immediately. The dog will not come home. The bite victim will need rabies post-exposure prophylaxis, which involves a dose of human rabies immune globulin and a series of rabies vaccine injections on days 0, 3, 7, and 14.2CDC. Rabies Post-Exposure Prophylaxis Guidance PEP is highly effective when started promptly, though it can cost several thousand dollars.
If the dog cannot be found or the owner is unknown, health officials generally recommend starting PEP as a precaution rather than waiting. Rabies is nearly 100% fatal once symptoms develop, so the medical calculus favors treatment whenever there is any uncertainty.
What the Bite Means for the Owner
The dog’s fate is only half of what a bite sets in motion. The owner faces civil liability for the victim’s medical costs, lost wages, and pain and suffering. About 35 states and the District of Columbia have strict liability statutes, meaning the owner is responsible regardless of whether the dog ever showed aggression before.3National Conference of State Legislatures.

The money adds up fast. In 2024, the average insurance payout for a dog-related injury claim was $69,272, and total payouts nationwide reached $1.57 billion.4Insurance Information Institute. US Dog-Related Injury Claim Payouts Hit $1.57 Billion in 2024 Standard homeowners and renters policies generally cover dog bite liability up to policy limits, which typically run $100,000 to $300,000.5Insurance Information Institute. Spotlight on: Dog Bite Liability After a bite, insurers often raise the premium, nonrenew the policy, or add an exclusion for the specific dog going forward. That creates a bind: a dangerous dog designation requires liability insurance that the market may now refuse to sell.
Criminal charges are also possible when an owner’s recklessness contributes to a serious attack. Prosecutors have brought involuntary manslaughter, criminally negligent homicide, and second-degree murder charges against owners after fatal attacks, with prison sentences in reported cases ranging from 18 months to 20 years. Even without a death, violating dangerous dog laws, leash laws, or quarantine orders can bring misdemeanor charges carrying fines and up to a year in jail. The criminal case runs separately from any civil lawsuit, so an owner can face both at once.
What a Bite Victim Should Do
If you were bitten, report the bite to local animal control or the police. Many jurisdictions require it, and in some areas treating medical professionals and veterinarians are required to report as well. The report creates the official record that starts the quarantine and the investigation.
Preserve evidence while it is fresh. Photograph your injuries before they are bandaged and again as they heal. Get the owner’s name, address, and proof of the dog’s rabies vaccination if you can. Write down the names and contact information of anyone who witnessed the bite. These details carry weight if the case later turns into a civil claim or a dangerous dog proceeding, and victims generally have between one and three years to file a lawsuit depending on the state’s personal injury statute of limitations.
