Dog bites and other dog-related attacks are a nationwide public-safety problem. They send hundreds of thousands of people to emergency departments, cause severe and sometimes fatal injuries, disrupt the work of delivery employees and other professionals, and generate more than a billion dollars in homeowners liability claims in a single year. But no one national database counts every bite, and the most frequently repeated statistic about annual dog bites comes from research conducted decades ago.

This guide brings the best available national evidence into one place. It explains what current U.S. datasets do and do not measure, who faces heightened risk, when attacks are more likely to occur, what injuries require urgent attention, how dog-bite laws vary across the country, and what an injured person can do to protect both health and legal rights.

Dog bite risks nationwide: key takeaways

• There is no single current national count of all dog bites. Surveys, hospital records, death certificates, insurance claims, and workplace reports each capture a different part of the problem.
• The often-cited estimate of roughly 4.7 million U.S. dog bites per year is based on a 1994 telephone survey, not a current national reporting system.
• Children face a disproportionate risk of severe injury, especially to the head, face, and neck. Very young children require active adult supervision around every dog, including a family dog.
• Many attacks involve a dog the injured person knows. Familiarity does not eliminate risk, and any dog may bite in the wrong circumstances.
• High-risk situations include a child interacting without close supervision, territorial behavior at a door or fence, pain or illness, guarding food or puppies, loose dogs, multiple-dog attacks, and work that requires entering yards or approaching homes.
• A bite may damage skin, nerves, tendons, muscles, eyes, bones, or blood vessels. A person can also be knocked down or pulled by a leash and suffer a fracture or traumatic brain injury without a bite.
• Rabies exposure requires a prompt public-health assessment. Tetanus protection, wound infection, and rare but dangerous bacterial complications also require medical attention.
• Dog-bite liability is state-specific. Some states impose statutory liability with defined exceptions; others rely more heavily on prior knowledge, negligence, local ordinances, or a combination of rules.
• Homeowners, renters, umbrella, commercial, landlord, and other insurance may be relevant. Coverage depends on the policy, the facts, exclusions, and applicable law.
• Serious cases should be evaluated before evidence disappears or a deadline expires. Contact Pritzker Hageman to tell us what happened.

What does “dog bite risk” include?

A nationwide discussion should not be limited to puncture wounds. Dog-related harm can arise when a dog:

• bites, tears, crushes, or shakes a person;
• jumps on, charges, or knocks someone to the ground;
• causes a bicyclist, runner, or motorcyclist to fall or swerve;
• pulls a person holding a leash, causing a fall or upper-extremity injury;
• attacks another animal while a person intervenes;
• corners or chases a worker, child, resident, visitor, or passerby; or
• creates an infection, rabies concern, scarring, disability, or psychological injury after the physical wound.

Insurance datasets may include both bites and other dog-related injuries. Medical datasets may be limited to people who reach a hospital. Death data may classify a person as bitten or struck by a dog. For accuracy, this guide uses the broader term dog-related injury when the source is not limited to bites.

Why no single statistic tells the whole story

The United States does not have a mandatory national registry into which every dog bite is entered. A minor wound may be cleaned at home and never reported. A serious attack may appear in an emergency-department database, an animal-control report, a workplace record, an insurance file, and a lawsuit. Those records can overlap, but they cannot be reliably matched nationwide.

The result is a measurement problem. A survey can estimate unreported bites but depends on memory and sampling. Emergency-department data capture medically significant injuries but omit urgent-care visits, physician-office visits, telehealth, and wounds treated elsewhere. Insurance data reflect claims under participating policies, not every attack. Death certificates capture the rarest and most severe outcomes.

The historical 4.7 million estimate: useful context, not current surveillance

A CDC report published in 2003 summarized a national telephone survey conducted in 1994. Researchers estimated that about 4.7 million people were bitten by dogs that year; approximately 799,700 sought medical attention, 333,700 went to an emergency department, and about 6,000 were hospitalized.

The estimate remains widely quoted because a newer all-bites national survey is not available. It can help explain that many bites never reach a hospital or insurer. It should not be described as the number of people bitten “each year” today without disclosing that the underlying survey measured 1994.

A credible modern resource should say both things clearly: the 1994 study suggested that the total burden was much larger than hospital records alone, and current national surveillance does not establish that the same number applies now.

Emergency-department injuries: a current measure of medically significant harm

A peer-reviewed national study of dog-bite injuries treated in emergency departments estimated 344,201 nonfatal visits in 2018. The researchers analyzed 2005 through 2018 data and found that the rate rose through 2011 and then declined through 2018. Dog bites were the 13th leading cause of nonfatal emergency-department injury in 2018 in the study’s ranking.

This measure is narrower than all bites and more useful for understanding injuries serious or concerning enough to prompt emergency care. It still omits people treated in urgent care, primary care, specialty clinics, or at home. It also does not capture a person’s later plastic surgery, counseling, infection treatment, or disability unless that later care generated another included emergency visit.

Fatal dog-related injuries

A peer-reviewed analysis of CDC WONDER mortality records identified 420 U.S. deaths with an underlying cause coded as bitten or struck by a dog, ICD-10 code W54, during 2018 through 2023. That equals an average of 70 deaths per year. The study also found that annual fatalities increased 2.7-fold between 2018 and 2023. These records exclude rabies deaths and do not provide a complete account of the circumstances surrounding each event.

A fatality count should never be used to minimize nonfatal harm. Deaths are uncommon compared with emergency visits, but they demonstrate the potential force and speed of an attack. Fatal events can involve blood loss, crushing injuries, head or neck trauma, infection, or a fall. Children, older adults, people with limited mobility, and people unable to escape or defend themselves can be especially vulnerable to catastrophic outcomes.

Current mortality queries can also be run through the CDC’s WISQARS injury data system. Because coding practices and finalized mortality years change, any future update to this article should record the query date, years selected, mechanism definition, and whether provisional or final data were used.

Insurance claims show the financial scale of dog-related harm

The Insurance Information Institute’s April 2026 analysis reported 28,450 homeowners liability claims involving dog bites and other dog-related injuries in 2025. Those claims cost insurers about $1.862 billion, and the average claim cost was $65,450.

The number of claims rose from 22,658 in 2024 to 28,450 in 2025, a 25.6 percent increase. Total cost rose 18.6 percent. The average cost declined 5.5 percent from $69,272 in 2024, but the 2025 average was still 97 percent higher than the 2016 average.

Those figures are not a verdict on the value of any individual case. A claim involving a small hand wound is different from one involving facial reconstruction, nerve damage, lost earning capacity, or death. The data also combine bites with some other dog-related injuries and reflect claims made under homeowners policies included in the analysis.

States with the most homeowners dog-related injury claims in 2025

State	Estimated claims	Average cost per claim	Estimated total cost
California	2,830	$81,789	$231.5 million
Florida	2,347	$62,375	$146.4 million
Michigan	1,432	$68,018	$97.4 million
Ohio	1,348	$41,413	$55.8 million
Pennsylvania	1,324	$68,786	$91.1 million
Texas	1,313	$70,885	$93.1 million
New York	1,308	$92,154	$120.5 million
Illinois	1,283	$79,596	$102.1 million
Indiana	824	$53,396	$44.0 million
New Jersey	818	$77,447	$63.4 million

These are raw claim counts, not population-adjusted risk rates. A populous state can generate many claims even if its per-resident rate is lower than that of another state. Policy prevalence, reporting behavior, insurance practices, housing, dog ownership, state law, and claim definitions can also influence rankings. It would be misleading to label these the “most dangerous states for dog bites” based on claims alone.

Worker risk: more than 5,200 USPS employee attacks in 2025

The U.S. Postal Service reported that its employees experienced more than 5,200 dog attacks in 2025. California recorded 673 incidents, followed by Texas with 358 and Ohio with 287. Los Angeles led the city list with 70 incidents.

These are occupational incidents within a single workforce, not a count of every U.S. delivery-worker attack. They nevertheless show how routine activities can create predictable exposure: opening a gate, approaching a porch, handing over mail, entering a yard, or encountering a dog that escapes through a door.

USPS advises owners to place dogs in a separate closed room before opening the door, make sure doors latch, use a leash outside, and avoid accepting mail in the dog’s presence. The agency warns that even a predictable pet may act differently when startled or defending territory.

Who faces the greatest risk of serious dog-bite injury?

Any person can be bitten, but exposure, body size, mobility, health, work, and the circumstances of an encounter affect both the likelihood and severity of injury. Risk should be understood as a combination of how often a person is exposed, whether the person can recognize and avoid danger, and how much harm the person’s body can withstand.

Children, especially very young children

Children are more likely than adults to be bitten and can suffer severe injuries at a lower point on the body. Historical CDC emergency-department data found that children ages 5 through 9 had the highest injury rate in 2001. Among children younger than 4, 64.9 percent of injuries involved the head or neck. These figures come from the CDC’s 2003 report and should be labeled by year, but the underlying safety lesson remains important.

The CDC’s current dog-safety guidance states that young children are more likely to be bitten and to be severely injured. It also emphasizes that many bites affecting young children happen during ordinary activities with familiar dogs.

A child may not recognize stiff posture, guarding, staring, lip licking, yawning, retreat, growling, or other signs that a dog wants space. A young child may hug, climb on, corner, wake, chase, or approach a dog that is eating. The child’s face may be close to the dog’s mouth. A supervising adult must be close enough to intervene immediately, not merely somewhere in the same home or yard.

After a child’s serious attack, the family should consider more than the initial wound. Facial growth can change the appearance of a scar. Additional procedures may be recommended after healing or as the child matures. Fear of dogs, nightmares, avoidance, guilt, school problems, and post-traumatic stress symptoms can also require treatment. Pritzker Hageman’s child safety lawyers evaluate the long-term effect of preventable injuries on children and families.

Older adults and people with mobility limitations

An older adult may be less able to move away, remain standing, protect the head and neck, or recover from a fracture. Falls can be devastating even when teeth never break the skin.

A Johns Hopkins analysis estimated that 422,659 adults were treated in U.S. emergency departments for injuries related to walking a leashed dog from 2001 through 2020. Finger fractures, traumatic brain injuries, and shoulder sprains or strains were among the most common injuries. The study found that older adults faced greater fracture and traumatic-brain-injury risk.

This does not mean older adults should avoid dogs. It means dog size and strength, leash equipment, training, terrain, footwear, balance, and the handler’s physical ability matter. A dog that lunges toward another animal or suddenly changes direction can produce enough force to pull a person down.

Delivery, utility, home-service, and public-safety workers

Postal carriers are not the only workers exposed to dogs. Package drivers, food-delivery workers, utility employees, cable technicians, home-health professionals, repair workers, landscapers, meter readers, police officers, firefighters, emergency medical personnel, property inspectors, and contractors may enter territory a dog perceives as protected.

Work-related attacks raise additional questions. Workers’ compensation may provide benefits without requiring proof that the dog owner was negligent. A separate claim against a dog owner, property owner, business, or another third party may also be possible, depending on the facts and state law. The interaction between benefits, liens, subrogation, and a third-party recovery requires careful analysis.

People with weakened immune systems or specific medical vulnerabilities

Any bite can become infected. Some people face a greater risk of severe complications because of a weakened immune system, cancer treatment, diabetes, absent or impaired spleen function, alcohol-use disorder, age, vascular disease, or other conditions.

The CDC explains that Capnocytophaga bacteria commonly live in the mouths of dogs and cats. Human infection is rare, but it can progress to sepsis, tissue death, gangrene, or amputation, particularly in people with certain risk factors. A clinician needs to know about the animal exposure and the patient’s health history.

People confronted by multiple dogs

Multiple-dog attacks can make escape and defense more difficult. The person may be pulled to the ground, attacked from different directions, or unable to protect the face and neck. The event may also complicate proof because the dogs can have different owners or handlers, and witnesses may not be able to identify which dog caused a particular wound.

Investigators should identify every dog, owner, keeper, property controller, witness, animal-control record, photograph, video, and insurance policy. A case should not be reduced to the conduct of the dog that left the most obvious bite mark if other failures contributed to the attack.

Familiar dogs can bite: why “the dog knows us” is not a safety plan

The idea that only stray or unfamiliar dogs are dangerous is false. A dog may react to pain, fear, surprise, competition, resource guarding, territorial behavior, restraint, handling, or a change in the home. The CDC notes that children are often bitten during everyday interactions with familiar dogs.

Familiarity can create overconfidence. Adults may allow a child to approach a sleeping dog, take a toy, climb into the dog’s bed, interrupt feeding, or touch a painful area because the dog has “never done anything before.” A lack of prior injury does not guarantee that a future interaction is safe.

Owners should respond to warning behavior rather than punish the warning out of the dog. Growling, freezing, retreating, showing the whites of the eyes, guarding, and snapping can signal stress or fear. Veterinary evaluation is important when behavior changes suddenly because pain or illness may be contributing.

Breed is not a substitute for evaluating behavior, control, and circumstances

Dog-bite prevention and liability discussions often become arguments about breed. That can obscure more actionable evidence: the individual dog’s history and behavior, whether the dog was secured, the number and size of dogs, the victim’s vulnerability, the owner’s supervision, and the conditions immediately before the event.

The American Veterinary Medical Association explains why breed-specific rules are not a complete answer. A dog’s breed alone does not reliably predict whether that individual dog will bite. Visual breed identification can also be inaccurate, particularly for mixed-breed dogs.

This does not mean physical characteristics are irrelevant to injury severity. Size, strength, jaw mechanics, number of dogs, duration of the attack, and the victim’s size and health can affect the damage. The sound approach is to evaluate the individual animal and the full event, not assume either safety or danger from a label alone.

High-risk dog-bite situations

Most attacks are not truly random. The exact bite may occur in seconds, but the risk often develops through a series of preventable conditions.

1. A young child and a dog are together without active supervision

“Supervised” should mean that an attentive adult is close enough to see the interaction and physically intervene. A baby gate, separate room, crate, or other secure separation is safer when an adult cannot give full attention. A child should never be expected to manage a dog’s warning signs alone.

2. A dog is eating, sleeping, injured, ill, caring for puppies, or guarding an object

Dogs may protect food, toys, resting spaces, territory, or offspring. Children and visitors should be taught to leave a dog alone in these situations. An owner who knows of guarding behavior should use barriers and professional guidance rather than depend on verbal warnings after a person is already within reach.

3. A visitor, worker, or delivery person approaches the home

Doors, porches, fences, gates, and driveways are recurring attack locations. The dog may rush through an opening, clear a fence, break a tether, or interpret an exchange as a threat. The owner should secure the dog before opening the door and keep the dog separated until the visitor has left.

4. A loose dog reaches a sidewalk, street, park, or neighboring property

A defective latch, open gate, inadequate fence, off-leash decision, or unattended tether can expose strangers who had no reason to expect a dog. A person lawfully using a public space should not have to determine whether an approaching dog is “friendly” while deciding whether to run, stand still, protect a child, or avoid traffic.

5. A person attempts to separate fighting dogs

Hands, arms, and faces can be injured when a person reaches between dogs or grabs a collar during a fight. The dog may redirect its bite toward the person. Emergency guidance should come from animal-control, veterinary, or public-safety professionals; improvised intervention can intensify the danger.

6. A dog is startled, cornered, hugged, restrained, or handled against its signals

Sudden waking, loud movement, forced contact, painful grooming, nail trimming, veterinary procedures, and being trapped without an escape route can increase stress. Owners and businesses should use appropriate handling plans, trained personnel, barriers, and warnings based on the individual dog.

7. A leash, tether, gate, crate, collar, or fence fails

Equipment should match the dog’s size, strength, and behavior. A retractable leash may give a dog enough distance to reach another person before the handler can regain control. A worn collar, low fence, unlocked gate, or tether attached to a weak fixture can transform a known risk into an attack.

8. Several dogs are loose together

Group arousal can escalate quickly. A chase, fence-line reaction, fight, or excitement around a visitor may draw in additional dogs. Owners, kennels, rescues, daycares, boarding facilities, and businesses need staffing, separation, intake, and emergency procedures that account for group behavior.

9. A business invites customers and dogs into the same space

Pet stores, dog-friendly patios, apartment common areas, groomers, veterinary facilities, boarding operations, daycares, adoption events, and retail locations can create overlapping duties. The facts may involve the dog’s owner, the business, an employee, a property controller, a contractor, or another entity. Read more about dog attacks at PetSmart and similar retail settings.

10. A landlord or property manager knows about a recurring danger but fails to act

Landlord liability is highly state- and fact-specific. Relevant evidence may include lease terms, pet restrictions, complaints, prior attacks, maintenance records, broken gates, common-area control, notices, and the legal power to remove or restrict the dog. Ownership of the building alone does not automatically establish liability, but documented control and notice can matter.

11. A dog is in pain or its behavior has recently changed

Arthritis, dental pain, injury, neurologic disease, vision or hearing loss, and other conditions can alter tolerance. A sudden behavioral change calls for veterinary assessment and stronger management while the cause is investigated.

12. A person runs, cycles, or moves quickly near an unsecured dog

Movement may trigger chasing. A cyclist can suffer a serious crash while avoiding a dog even without contact. The legal analysis may involve the dog owner’s control, leash law, roadway conditions, and proof that the dog’s conduct caused the fall.

What injuries can a dog bite or attack cause?

The external wound may not reveal the full damage. Teeth can create narrow punctures while crushing deeper tissue. Pulling and shaking can enlarge the injury. A person can also suffer blunt-force trauma or a fall.

Punctures, lacerations, avulsion, and tissue loss

A puncture can drive bacteria below the surface. A laceration may require irrigation, debridement, closure, or staged repair. Avulsion occurs when tissue is torn away. Severe attacks can remove part of an ear, lip, nose, scalp, finger, or other structure and may require grafting or reconstruction.

Nerve, tendon, muscle, and blood-vessel damage

Hand, wrist, forearm, leg, and facial wounds can damage structures responsible for sensation, movement, expression, and blood flow. Numbness, weakness, limited range of motion, chronic pain, cold sensitivity, and loss of dexterity can persist after the skin closes.

Fractures and crush injuries

A bite can fracture small bones. A dog can knock a person down, and a fall can fracture the wrist, arm, hip, ankle, or facial bones. Crushing and prolonged pressure can compromise tissue and circulation.

Eye and vision injuries

A bite or claw can injure the eyelid, tear duct, orbit, cornea, or eye itself. Facial swelling can make the extent of injury difficult to assess. Prompt specialist evaluation can be critical. Pritzker Hageman provides additional information about serious eye injury claims.

Traumatic brain injury and concussion

A person may strike the head while falling, be knocked into an object, or sustain facial and skull trauma. Loss of consciousness is not required for a concussion. Headache, vomiting, confusion, unusual sleepiness, balance problems, memory changes, or behavior changes warrant urgent assessment. See the firm’s guide to traumatic brain injury cases.

Infection

Redness, warmth, swelling, increasing pain, drainage, red streaks, fever, chills, or reduced function may indicate infection. Hand bites, deep punctures, delayed treatment, crushed tissue, and certain medical conditions can increase concern. Medical professionals decide whether antibiotics, imaging, surgery, or hospital care are needed.

Scarring and disfigurement

Scars may be raised, depressed, discolored, painful, itchy, tight, or sensitive. A facial scar can affect expression and identity. A scar crossing a joint can limit motion. Treatment may include silicone products, injections, laser treatment, revision, grafting, or other procedures. The final appearance may not be known for months.

Amputation

Severe tissue destruction, vascular injury, infection, or gangrene can make amputation medically necessary. Loss of a finger or limb can affect work, self-care, balance, recreation, and emotional health. Learn more about the firm’s amputation practice.

Psychological injury

Fear, intrusive memories, nightmares, panic, avoidance, depression, guilt, and post-traumatic stress symptoms can follow an attack. A child may stop playing outside, visiting friends, or sleeping alone. An adult may be unable to return to a delivery route, neighborhood, or job. Psychological harm deserves evaluation and treatment just as physical harm does.

Death

Fatal cases require immediate evidence preservation. Animal-control records, body-camera footage, emergency calls, photographs, veterinary history, prior complaints, property records, witness accounts, and insurance information can disappear or become harder to obtain. Families can learn about wrongful-death claims and ask for a prompt case review.

What should you do after a dog bite or attack?

Medical safety comes first. The right response depends on the severity of the wound, the person’s age and health, the location of the injury, whether the dog can be identified, and what happened during the attack.

1. Get away from the dog without escalating the encounter

Move behind a solid barrier if possible. Do not make sudden movements that increase pursuit. If the dog knocks you down, protect your head and neck and curl into a compact position when you can. Do not attempt to capture an unknown dog yourself.

2. Control bleeding and clean minor wounds

Use clean material and direct pressure for bleeding. For a minor wound, wash promptly with soap and running water. Deep punctures, crushed tissue, facial wounds, hand wounds, significant bleeding, and wounds in a medically vulnerable person require professional evaluation even when the surface looks small.

3. Obtain prompt medical care

Tell the clinician exactly how the injury occurred, when it happened, the body areas affected, whether the dog is available for observation or testing, and whether you have conditions that increase infection risk. Ask what symptoms require urgent reassessment and when follow-up should occur.

A legal claim should never drive a medical decision. Follow the treating professional’s recommendations, keep appointments, and report new symptoms. Gaps in care can harm recovery and later make it harder to understand which problems were caused by the attack.

4. Ask about rabies exposure

Rabies is almost always fatal after symptoms begin, but timely post-exposure treatment is highly effective. The decision is not based solely on whether the owner can immediately produce a vaccination certificate. Public-health professionals consider the species, behavior, availability of the animal, local rabies epidemiology, type of contact, and other facts.

The CDC’s rabies post-exposure guidance states that people who may have been exposed should receive a risk assessment. When post-exposure prophylaxis is indicated for a person not previously vaccinated, it generally includes immediate wound care, human rabies immune globulin, and vaccine doses on days 0, 3, 7, and 14. Immunocompromised patients may need an additional dose and follow-up testing. A public-health or medical professional must make the decision for the individual exposure.

Do not try to capture a loose or wild animal at the risk of another injury. Contact animal control or law enforcement. If the dog is known, preserve the owner’s identity and the animal’s description so authorities can determine whether observation or testing is appropriate.

5. Review tetanus protection

Animal bites are considered dirty or major wounds because saliva can contaminate damaged tissue. The CDC’s tetanus wound-management guidance explains that vaccination recommendations depend on the wound and vaccination history. For a person who completed the primary series, a booster is generally considered for a dirty or major wound when five or more years have passed since the last tetanus vaccine. People with an unknown or incomplete series may need vaccination and, in some circumstances, tetanus immune globulin.

A clinician should make the recommendation. Antibiotics do not prevent tetanus.

6. Watch for infection and systemic illness

Follow wound-care instructions. Seek prompt reassessment for increasing redness, warmth, swelling, pain, drainage, fever, chills, red streaks, reduced motion, numbness, weakness, foul odor, discoloration, or feeling suddenly ill.

Rare infections can progress rapidly. The CDC’s Capnocytophaga information describes symptoms including blisters around the wound, redness or swelling, fever, diarrhea or stomach pain, headache or confusion, and muscle or joint pain. People without a spleen, people with weakened immunity, and people with certain alcohol-use patterns face increased risk of severe disease.

7. Report the attack to the appropriate local authority

Animal-control or law-enforcement reporting can protect other people, help locate and observe the dog, document the event, and identify prior incidents. Reporting rules vary. Ask for the report number and the name of the agency handling the matter.

Be accurate. Describe what you saw and experienced without guessing about breed, intent, ownership, prior behavior, or facts you did not personally observe. Correct a material error in a report promptly and in writing when possible.

8. Identify the dog, owner, handler, property, and witnesses

Obtain names, addresses, telephone numbers, email addresses, vehicle information, and the location where the dog is normally kept. Identify the person who controlled the property and anyone who saw the dog before, during, or after the incident.

If doing so is safe, note the dog’s size, color, markings, collar, tags, and direction of travel. Avoid confrontation. Police or animal control can assist when the owner refuses information or the dog remains dangerous.

9. Preserve photographs and physical evidence

Photograph the injury before and after cleaning when medical safety permits, then throughout healing. Use consistent lighting and include wide and close views. Photograph torn clothing, blood, the location, gates, fencing, signs, leashes, broken equipment, and sight lines.

Keep damaged clothing, shoes, glasses, phones, bicycles, bags, or equipment in a clean, dry place. Do not repair, discard, or give an insurer the only version of an item without first documenting it and getting advice.

10. Preserve digital evidence quickly

Doorbell cameras, security systems, delivery apps, dash cameras, body cameras, business cameras, and nearby homes may have recorded the attack or the dog’s earlier behavior. Many systems overwrite video in days. Send a written preservation request to the person or entity controlling the footage.

Save text messages, social-media posts, online warnings, neighborhood-app discussions, photographs, and communications with the owner, landlord, business, animal control, or insurer. Preserve the original file and metadata rather than relying only on a screenshot when possible.

11. Document medical, financial, and daily effects

Keep medical records, bills, pharmacy receipts, mileage, wage-loss documents, school records, repair or replacement receipts, and correspondence. Maintain a simple contemporaneous journal of pain, sleep, wound care, limitations, missed activities, fear, and assistance needed.

Do not exaggerate. A specific, honest record is more useful than a dramatic one. Note good days as well as difficult days and update the record when a diagnosis, work restriction, surgery recommendation, or prognosis changes.

12. Use care when communicating with insurance companies

An adjuster may request a recorded statement, medical authorization, photographs, prior records, or a release. The insurer’s role is to evaluate exposure under the policy, not to advise the injured person about the full value of the claim.

A broad medical authorization may reach unrelated records. A release can end the claim even if a scar matures poorly or another procedure is later recommended. Before signing, understand what information is being requested, what rights are being released, what liens or reimbursement obligations may apply, and whether future harm has been evaluated.

13. Speak with a lawyer before evidence or deadlines are lost

Different deadlines can apply to injury claims, claims against government entities, workers’ compensation, minors, estates, insurance notice, and preservation of evidence. Waiting can also make a case harder even when the formal limitations period has not expired.

How do dog-bite laws vary across the United States?

There is no single federal civil-liability rule for dog bites. State statutes, state court decisions, city or county ordinances, property law, insurance contracts, workers’ compensation rules, and the facts of the event can all matter.

The phrase “one free bite” is misleading. Even in a state that considers whether an owner knew or should have known of dangerous tendencies, proof can come from more than a prior bite. Lunging, snapping, chasing, escaping, fighting, threatening visitors, prior complaints, warning signs, restraint practices, or the owner’s own statements may be relevant. Negligence or ordinance violations may provide another path to liability.

A January 2026 National Conference of State Legislatures overview classified about 10 states as using variations of a one-bite rule and described 35 states, the District of Columbia, and four territories as having strict-liability laws. Classifications differ because statutes contain important conditions and exceptions. The Michigan State University Animal Legal and Historical Center’s state table illustrates those variations.

Legal framework	Core question	Evidence that may matter
Statutory or strict liability	Does a state statute impose liability when its conditions are met, regardless of prior knowledge?	Lawful presence, provocation, victim conduct, dog ownership or keeping, location, law-enforcement exceptions, and whether the statute covers bites or any injury
Knowledge-based or “one-bite” rule	Did the owner know or have reason to know the dog had dangerous or abnormal tendencies?	Prior bite, snapping, lunging, chasing, fighting, escape history, complaints, warnings, training records, and owner statements
Negligence	Did a person or entity fail to use reasonable care under the circumstances?	Leash or fence failures, supervision, property control, policy violations, foreseeability, staffing, handling, and compliance with ordinances
Negligence per se or statutory violation	Did violation of a safety law or ordinance establish or support breach?	The rule’s purpose, protected class, causation, excuses, and the jurisdiction’s treatment of statutory violations
Premises or landlord liability	Did a property controller have notice, control, and a duty to address the condition?	Lease, complaints, common-area control, inspection, broken barriers, authority over the dog, and prior incidents
Business or institutional liability	Did a business, employer, school, facility, rescue, or other entity create or fail to manage a foreseeable risk?	Policies, training, staffing, intake records, warnings, placement decisions, supervision, and ownership or control

Common statutory exceptions and defenses

The details vary, but dog-bite statutes may address:

• provocation, including how the jurisdiction treats intentional and unintentional acts;
• trespass or other unlawful presence;
• crimes or attacks on the owner or another person;
• law-enforcement and military dogs performing official duties;
• warning signs or conduct in restricted areas;
• comparative or contributory fault;
• assumption of risk for veterinarians, handlers, groomers, kennel workers, or others with occupational exposure;
• the difference between a legal “owner,” “keeper,” “harborer,” or person with custody; and
• whether the law covers only a bite or any injury caused by the dog.

A defense is not established merely because an insurer or owner mentions it. The legal definition, burden of proof, and actual evidence matter.

Minnesota dog-bite law as one example of statutory liability

Minnesota has a specific dog-injury statute. Minnesota Statutes section 347.22 generally provides that when a dog, without provocation, attacks or injures a person who is peaceably conducting themselves in a place where they may lawfully be, the dog’s owner is liable for the full amount of the injury. The statute defines “owner” to include a person harboring or keeping the dog, while making the actual owner primarily liable.

The statutory words matter. A Minnesota case may turn on whether the injured person was acting peaceably, was lawfully present, provoked the dog under Minnesota law, and whether a person other than the title owner was harboring or keeping the dog. Other legal theories can also require analysis.

This is why a generic statement that every state gives a dog “one free bite” is wrong, and why a generic statement that every dog owner is automatically liable is also wrong. The jurisdiction and facts must be examined together. The firm’s Minnesota dog-bite attorneys can explain how the law may apply to a particular event.

Who may be legally responsible after a dog attack?

The obvious defendant is not always the only one, and the person holding the leash may not be the legal owner. A complete investigation asks who created, controlled, knew about, insured, or had the legal ability to correct the danger.

Dog owner

The owner may face statutory liability, negligence liability, or both. Relevant evidence can include ownership records, licensing, veterinary files, adoption papers, prior incidents, training, warnings, restraints, and statements made before or after the attack.

Keeper, harborer, custodian, walker, or handler

Some statutes extend responsibility beyond the title owner. A person who regularly keeps, houses, controls, walks, or supervises a dog may fit a statutory definition or owe an independent duty of care.

Landlord, property manager, or homeowners association

Liability is not automatic. It may depend on notice, control, common-area responsibility, lease authority, maintenance failures, and state law. A broken gate under the landlord’s control creates a different analysis from an attack entirely inside a tenant’s private premises with no prior notice.

Business or commercial property operator

A store, restaurant, hotel, apartment operator, daycare, veterinary clinic, groomer, kennel, rescue, boarding facility, or event organizer may be responsible for its own policies, premises, employees, or handling decisions. The dog’s owner can remain responsible at the same time.

Employer

An employer may be responsible for an employee’s conduct within the scope of employment or for workplace safety failures. If the injured person is an employee, workers’ compensation may also apply.

Government entity

Police dogs, government-owned property, animal-control decisions, and attacks involving public employees can trigger special immunities, notice requirements, and short deadlines. Prompt legal review is especially important.

Manufacturer or seller of failed equipment

In an unusual case, a defective leash, collar, harness, gate component, crate, or restraint system may contribute. Product preservation and expert examination become important. Ordinary wear, misuse, installation, and maintenance must be distinguished from a product defect.

What insurance may cover a dog-bite claim?

Potential coverage can include homeowners, renters, umbrella, excess, landlord, commercial general liability, business, farm, auto, and specialized animal-liability policies. Workers’ compensation, health insurance, Medicare, Medicaid, disability benefits, and other programs may pay certain losses while creating reimbursement rights.

Coverage is not automatic. A policy may contain an animal exclusion, dog-specific exclusion, business-use restriction, location condition, notice requirement, intentional-act provision, limit, deductible, or reservation of rights. The insured’s status and the place of the attack can affect the analysis. State law may restrict or interpret exclusions differently.

Do not assume there is no coverage because the dog owner rents, does not own the attack location, or says the policy “doesn’t cover dogs.” Do not assume there is coverage because the attack happened at a house. Obtain and review the actual policy and every potentially applicable policy.

A serious claim can exceed a primary policy limit. An umbrella policy, another insured, a commercial policy, or personal assets may become relevant. A lawyer can identify coverage, request disclosures permitted by law, coordinate benefits, and evaluate whether an insurer is handling the claim appropriately.

What compensation may be available?

Compensation depends on governing law, proof, causation, insurance, collectability, and the individual harm. No responsible lawyer can value a case from a wound photograph or national average alone.

Potential damages may include:

• emergency transportation and treatment;
• hospitalization, surgery, medication, rehabilitation, and follow-up care;
• plastic surgery, scar management, dental care, eye care, or future procedures;
• counseling and treatment for post-traumatic stress, anxiety, or depression;
• lost wages, lost earning capacity, and loss of employment benefits;
• pain, disability, disfigurement, emotional distress, and loss of normal life;
• assistance with household tasks and personal care;
• damaged clothing, glasses, phones, bicycles, or other property;
• funeral and burial expenses and other wrongful-death damages where allowed; and
• other losses recognized by the applicable jurisdiction.

Medical liens, workers’ compensation liens, health-plan reimbursement rights, subrogation, taxes, structured settlements, guardianship or court approval for minors, and allocation among claimants can affect the net recovery. Read more about dog-bite compensation.

Can punitive damages be awarded?

Punitive damages are exceptional and state-specific. They are not simply extra compensation whenever the injuries are severe or compensatory damages feel inadequate. The purpose, proof standard, pleading procedure, and available amount vary by jurisdiction.

Minnesota, for example, generally requires clear and convincing evidence that the defendant acted with deliberate disregard for the rights or safety of others under Minnesota Statutes section 549.20. A plaintiff generally may not include a punitive-damages claim in the initial complaint and must later seek permission to amend under section 549.191 by presenting the required prima facie showing.

Evidence such as repeated attacks, explicit warnings, deliberate release, concealment, chronic restraint failures, or conscious refusal to correct a known extreme danger may be relevant, but the facts must satisfy the controlling law. See the firm’s page on punitive damages after a dog attack.

What evidence can establish what happened and what was known before the attack?

Dog-bite cases often turn on evidence controlled by other people. A prompt, targeted investigation can reveal whether the event was truly unforeseeable or followed a pattern.

Animal-control and law-enforcement records

Prior complaints, citations, dangerous-dog proceedings, bite reports, dispatch records, body-camera footage, photographs, quarantine records, and witness names may show notice, recurring escape, or inconsistent accounts. Requests should identify the dog, owner, address, date range, and all relevant agencies.

Veterinary, training, boarding, and adoption records

These records may contain behavior notes, muzzle recommendations, aggression during handling, bite history, medication, surrender reasons, or instructions given to the owner. Access may require authorization, subpoena, or litigation procedures.

Housing and property records

Leases, pet addenda, applications, complaints, emails, inspection records, maintenance requests, fence or gate repairs, association rules, and notices can address control and notice. Photographs and measurements should document conditions before repairs or weather changes them.

Digital and social evidence

Doorbell video, security footage, delivery notes, texts, emails, online posts, neighborhood messages, and photographs may show escape history, owner knowledge, or the attack itself. Authenticity and completeness matter. Preserve the original data and context.

Witness testimony

Neighbors, prior visitors, delivery workers, family members, tenants, employees, trainers, veterinary staff, and other witnesses may have observed behavior or warnings. Record names and contact information promptly; memories fade and people move.

Medical and expert evidence

Treating professionals document the injury, infection risk, surgery, prognosis, scars, function, and psychological harm. Depending on the case, experts in plastic surgery, hand surgery, neurology, vocational loss, life-care planning, animal behavior, premises safety, economics, or other fields may be needed.

How can dog bites be prevented?

Prevention is a shared responsibility, but ownership carries the central duty to manage the dog. A person should not have to absorb the risk created by an owner who ignores behavior, allows escape, or places a vulnerable child in an unsafe interaction.

Safety steps for parents and caregivers

• Never leave a baby or young child alone with a dog, including a family dog.
• Use physical separation when active supervision is not possible.
• Teach children not to disturb a dog that is sleeping, eating, injured, hiding, guarding, or caring for puppies.
• Do not allow climbing, riding, hugging, face-to-face contact, ear pulling, tail pulling, or taking food and toys.
• Ask an owner before approaching an unfamiliar dog, and accept “no” immediately.
• Do not encourage a child to prove bravery around a fearful or uncomfortable dog.
• Model calm behavior. Do not run toward a dog, scream in its face, or reach through a fence.
• Treat growling, freezing, retreating, guarding, or snapping as a reason to separate, not as disobedience to punish in the moment.
• Seek qualified veterinary and behavior help for concerning conduct.
• Make a child-specific plan for visits, parties, sleepovers, childcare, and homes with dogs.

The CDC’s dog safety page and the AVMA’s dog-bite prevention resources provide additional guidance.

Safety steps for dog owners

• Choose a dog whose size, energy, needs, and behavior fit the household’s ability to provide care and control.
• Arrange appropriate veterinary care, socialization, and humane, evidence-based training.
• Learn the individual dog’s stress signals and triggers.
• Use secure doors, gates, fencing, leashes, collars, harnesses, crates, and barriers appropriate for the dog.
• Separate the dog before opening the door for a visitor or delivery.
• Do not let a dog roam or rely on an invisible boundary where the dog can still reach a person.
• Supervise every child-dog interaction closely.
• Address pain, illness, sudden behavior change, guarding, escape, lunging, or aggression promptly.
• Follow leash, licensing, vaccination, dangerous-dog, and restraint requirements.
• Give walkers, sitters, tenants, guests, employees, and family members clear, accurate safety information.
• Carry adequate liability insurance and disclose the dog truthfully when applying for or renewing coverage.
• Create an emergency plan before a bite occurs.

Safety steps for landlords and property managers

Landlords should use lawful, consistently applied policies; document complaints; inspect and repair common-area gates, doors, and fences; enforce lease terms; and respond to known hazards. Staff should know how to report an incident and preserve video, records, and witness information.

A breed label is not a substitute for a behavior- and control-based safety process. A policy should focus on lawful occupancy, reliable restraint, documented conduct, reasonable accommodations where required, and prompt response to actual risks.

Safety steps for businesses and organizations

Businesses that permit, board, handle, place, groom, treat, train, or display dogs need written procedures that employees actually follow. Depending on the operation, those procedures may address intake history, vaccination, behavior screening, separation, staffing ratios, protective barriers, incident response, warnings, emergency contacts, and record retention.

Customer-facing staff should not be expected to improvise during a fight or attack. Training should cover how to summon help, protect customers, secure other animals, preserve video, identify witnesses, and provide accurate reports.

Safety steps for delivery and home-service workers

Employers should collect and share address-specific dog warnings, allow workers to stop when conditions are unsafe, provide training and protective procedures, and support reporting without retaliation. Workers should follow employer safety rules, avoid entering when a loose dog is present, announce entry when appropriate, keep a barrier available, and document recurring hazards.

An owner who expects a delivery or service visit should secure the dog before the worker arrives. A verbal assurance that the dog is friendly is not a physical barrier.

Frequently asked questions about dog bite risks nationwide

How many dog bites happen in the United States each year?

No current national system counts every bite. The widely repeated estimate of about 4.7 million people bitten comes from a 1994 survey summarized by the CDC. A more recent national study estimated 344,201 nonfatal emergency-department visits for dog bites in 2018. These figures measure different things and should not be treated as interchangeable.

Are dog bites increasing nationwide?

The answer depends on the dataset and period. The emergency-department study found the rate increased through 2011 and then declined through 2018. Homeowners dog-related injury claims increased sharply from 2024 to 2025. Those trends can coexist because the datasets cover different events, populations, years, and reporting systems.

Which state has the most dog bites?

There is no complete state-by-state count of every bite. California had the largest number of homeowners dog-related injury claims in the 2025 Insurance Information Institute analysis and the most USPS employee incidents in 2025, but it is also the most populous state. Raw counts do not establish the highest per-capita bite risk.

What age group is most at risk?

Children face a high risk of being bitten and seriously injured. Historical CDC data identified children ages 5 through 9 as having the highest emergency-department injury rate in 2001, while very young children often sustained head and neck injuries. Older adults can face heightened risk of fractures and brain injury from being knocked down or pulled by a leash.

Do most attacks involve unfamiliar dogs?

No. Many bites happen during ordinary interactions with a dog the person knows. Family dogs and other familiar dogs still require supervision, boundaries, and appropriate management.

Can a dog cause a legal injury without biting?

Yes. A dog may knock a person down, pull a handler to the ground, chase a cyclist into a crash, or cause another foreseeable injury. Some statutes and insurance datasets expressly include injuries caused by a dog, not only wounds made by teeth.

Is a first bite always excused?

No. “One free bite” is an oversimplification. Many states have statutes that do not require proof of a prior bite when their conditions are met. In knowledge-based jurisdictions, other warning conduct may establish notice. Negligence can also exist without a prior attack.

Does provocation always defeat a claim?

No. The legal definition and effect of provocation vary. The age and capacity of a child, whether the conduct was intentional, whether the response was proportionate, and the wording of the state statute can matter. An owner’s accusation is not the final legal determination.

Can a child be blamed for provoking a dog?

The answer is jurisdiction-specific and fact-intensive. Courts may consider the child’s age, capacity, conduct, and the applicable statute or fault rule. Adults responsible for the child and dog may also have failed to supervise or separate them. A serious child-injury case should be evaluated under the actual state law rather than an insurer’s shorthand.

Is the owner liable if the bite happened on the owner’s property?

Possibly. A person can be lawfully on private property as a guest, customer, tenant, delivery worker, contractor, or for another permitted purpose. Statutory conditions, trespass rules, negligence, warnings, control, and the reason for entry can affect the case.

Is a landlord responsible for a tenant’s dog?

Sometimes, but not automatically. Liability can depend on prior notice, control over the relevant area, authority under the lease, common-area duties, maintenance failures, and state law. Preserve complaints, lease documents, photographs, and communications.

Can a store or restaurant be responsible for a customer’s dog?

Potentially. A business may be responsible for its own premises, policies, employees, warnings, or response to a known hazard. The dog owner may also be liable. The result depends on foreseeability, control, notice, and state law.

Does homeowners insurance always cover dog bites?

No. Many policies provide personal-liability coverage, but exclusions, limits, location, business use, prior incidents, animal restrictions, and insured status can affect coverage. Renters, umbrella, commercial, landlord, or other policies may also apply.

Should I give the insurance company a recorded statement?

You should understand who the adjuster represents, why the statement is requested, how it may be used, and whether you have legal advice. Be truthful and preserve your own account, but do not guess. A serious injury may justify speaking with counsel before a recorded interview or broad authorization.

How long do I have to bring a dog-bite claim?

Deadlines vary by state and claim type. Claims involving a government entity may have notice periods much shorter than the ordinary injury statute of limitations. Special rules may apply to minors, incapacitated people, estates, workers’ compensation, and contractual insurance notice. Prompt review is safer than assuming years remain.

What if the dog owner is a friend, neighbor, or relative?

A claim is often handled by liability insurance rather than paid directly from the person’s checking account. The relationship can make the process emotionally difficult, but it does not erase medical bills, lost income, scars, or future care. A lawyer can communicate with the insurer and explain options. See the firm’s discussion of claims involving a neighbor’s dog.

What if I was bitten while working?

Report the injury to the employer and seek medical care under the applicable workers’ compensation process. A third-party claim against the dog owner, property controller, or another entity may also exist. Do not sign away rights or assume workers’ compensation is the only potential source of recovery.

What if the dog cannot be found?

Seek medical care and contact public health, animal control, or law enforcement immediately. Rabies decisions are time-sensitive and depend on the exposure and local conditions. Provide the most detailed description possible, but do not endanger yourself by trying to capture the dog.

Should every bite be closed with stitches?

No universal rule applies. Location, depth, contamination, time since injury, tissue damage, infection risk, and cosmetic concerns influence wound management. A qualified clinician should decide whether to close, delay closure, leave open, debride, image, or refer the wound.

When should I worry about infection?

Seek medical advice for increasing redness, swelling, warmth, pain, drainage, fever, red streaks, numbness, weakness, reduced motion, discoloration, or systemic illness. People with weakened immunity, no spleen, diabetes, vascular problems, or other vulnerabilities should be especially cautious.

Can I recover for fear, nightmares, or post-traumatic stress?

Psychological injury can be a real consequence of an attack. Whether and how it is compensable depends on state law and proof. Prompt evaluation, appropriate treatment, and documentation help both recovery and accurate assessment of the harm.

How much is a dog-bite case worth?

There is no reliable calculator. Value depends on liability, jurisdiction, insurance, medical proof, scarring, function, future care, income loss, psychological harm, fault defenses, liens, and collectability. National average claim data cannot value an individual case.

Why hire a lawyer for a serious dog-bite case?

A lawyer can investigate ownership and prior notice, preserve video and records, analyze state law, identify insurance, coordinate benefits and liens, work with medical experts, document future harm, negotiate, and file suit when appropriate. Serious child injuries, facial wounds, nerve or tendon damage, amputation, brain injury, infection, and death deserve careful evaluation.
