Postal Worker Dog Bites: How Chicago Compares to Every Major U.S. City
Every working day, more than 300,000 U.S. Postal Service letter carriers walk up to front doors across the country, and a growing number of them are being attacked by dogs. The USPS tracks every dog bite incident involving its employees and publishes annual city and state rankings as part of its National Dog Bite Awareness Campaign. Because carriers visit nearly every residential address on a daily basis, this federal dataset serves as one of the most consistent, geographically detailed measures of dog bite risk in the United States.
The numbers are moving in the wrong direction. In 2024, more than 6,000 postal workers were attacked by dogs nationwide, up from approximately 5,300 in 2022 and roughly 5,800 in 2023. That 15% increase over just two years pushed the total to its highest level in at least seven years.
Chicago sits near the top of every ranking. The city placed third among all U.S. cities for mail carrier attacks in both 2023 and 2024, behind only Los Angeles and Houston. Illinois ranked fourth among all 50 states in 2024, and between 2022 and 2023 it recorded the largest percentage increase in postal worker attacks of any state in the country at 29%. This report breaks down how Chicago and Illinois compare to every other major city and state, examines the year-over-year trajectory, and explores what these attacks cost victims, dog owners, and the communities where dog bite injuries are concentrated.
DID YOU KNOW...?
Animal Attacks on USPS Mail Carriers Hit a Seven-Year High
The three-year trend shows a clear and accelerating problem. After dipping below 5,400 attacks in 2022, the national total rebounded sharply to more than 5,800 in 2023 before crossing the 6,000 mark in 2024. That means the rate of attacks grew faster in the most recent year, suggesting the issue is not stabilizing.
The Midwest is the most dangerous region for letter carriers. An NBC News analysis of 2024 USPS data found that Midwestern states averaged 5.24 dog attacks per 100,000 households, a rate 75% higher than the South. Chicago's persistent third-place city ranking and Illinois's fourth-place state ranking are part of this broader regional concentration.
Each of these incidents carries real consequences for the carrier involved. Dog bite injuries can require emergency care, surgery, and months of rehabilitation. They also affect entire neighborhoods: when a carrier feels unsafe, USPS can halt mail delivery for every address on the route, not just the home with the aggressive dog. Service is not restored until the animal is properly restrained. Understanding why dogs bite is the first step toward reversing these trends.
Chicago Holds Steady at 3rd Most Dangerous for Postal Worker Dog Bites
Nine of the ten cities saw attacks increase from 2023 to 2024. Cleveland was the sole exception, dropping from 44 to 37 attacks, a 15.9% decline. Every other city on the list grew, with Denver (+25.9%), San Francisco (+25.0%), and Cincinnati (+18.9%) posting the steepest increases.
Chicago's 18.8% increase matched the growth rate of Los Angeles and Sacramento, but what makes Chicago's position more concerning is the trend behind the headline number. Chicago has held the third spot for at least two consecutive years, and the city's 2024 total of 57 represents a significant jump from the 48 recorded in 2023. For a city where certain dog breeds present elevated bite risk, the upward trajectory demands attention from both animal control authorities and dog owners.
The concentration in a handful of cities is striking. The top four cities alone accounted for 246 of the more than 6,000 attacks nationwide in 2024. But thousands of additional incidents occurred in smaller cities and suburban areas that do not make the ranked list, meaning the national problem extends well beyond these urban hotspots.

Illinois Posts the Fastest Growth Rate for Dog Bites in the Country
California, Texas, and Ohio have held the top three state positions for multiple years, driven largely by their population size and geographic spread of postal routes. But Illinois's story is different: the state's ranking is rising not because of its size, but because attacks are growing faster there than anywhere else.
Between 2022 and 2023, Illinois recorded a 29% increase in postal worker dog attacks, the largest percentage jump of any state in the country. That growth pushed Illinois from outside the top five into fourth place by 2024 with 344 incidents, leapfrogging New York and Pennsylvania. The state continued to climb even as several of its peers saw slight declines.
Three of the top five states actually saw attacks decline from 2023 to 2024: California dropped 3.6%, Ohio fell 2.5%, and New York declined 3.6%. That makes the states still climbing, Illinois (+8.9%), Texas (+6.6%), and Michigan (+5.4%), even more conspicuous.
Illinois's trajectory is the most aggressive in the country. Between 2022 and 2023, the state posted a 29% year-over-year increase, the single largest jump of any state tracked by the USPS. The 2023-to-2024 growth moderated to 8.9%, but the two-year compounding effect has moved Illinois from approximately 245 attacks in 2022 to 344 in 2024, a cumulative increase of roughly 40% in just two years.
Chicago alone accounted for roughly one in six of the state's total incidents in 2024 (57 of 344), meaning the remaining 287 attacks were distributed across the rest of the state's postal routes, from the collar counties to downstate communities. The problem is not confined to Chicago, but Chicago is its most visible concentration point.
Year-Over-Year Trend of Postal Worker Dog Bites
The chart tells a story of a brief reprieve followed by a sharp reversal. In 2019, the USPS recorded 5,803 attacks, a number that had already been declining from a peak of 6,755 in 2016. The pandemic years disrupted normal delivery patterns, and by 2022 the total had fallen to approximately 5,300.
Then the rebound began. Animal attacks surged 9.4% in a single year from 2022 to 2023, effectively erasing the pandemic-era decline. By 2024, the total crossed 6,000 for the first time since at least 2017, marking a new post-pandemic high. The 2024 increase of 3.4% over 2023 was smaller in percentage terms, but it added to an already elevated base, pushing the absolute number higher.
Experts point to several factors behind the rebound. Dog ownership rose sharply during the pandemic, with the AVMA reporting 89.7 million dogs in U.S. households by 2024, up from 80.1 million in 2023. Many of those pandemic-era dogs did not receive proper socialization during lockdown periods, and as delivery volumes increased and carriers returned to pre-pandemic schedules, the combination of more dogs and less training produced predictable results.

Chicago in Focus: 57 Animal Attacks and Climbing
Chicago's 57 carrier attacks in 2024 put it closer to the top two cities than the visual might suggest. Los Angeles serves a vastly larger geographic footprint with more than 3.8 million residents compared to Chicago's 2.7 million, yet LA recorded only 20 more incidents. On a per-capita basis, Chicago's attack rate is comparable to, and may even exceed, that of the cities ranked above it.
The 2023-to-2024 jump from 48 to 57 represents nearly one additional attack per month. That sustained acceleration, combined with Illinois's nationally leading growth rate, suggests that the conditions driving attacks in Chicago, density of dog ownership, leash law compliance, and the prevalence of settings where dog bites commonly occur, are getting worse rather than better.
Briskman Briskman & Greenberg has represented postal workers and delivery drivers who have suffered dog bite injuries while on their routes. USPS carriers, UPS drivers, and Amazon delivery workers all face the same risk: a dog that perceives a uniformed stranger approaching its territory as a threat. Under Illinois's strict liability law, the dog's owner is financially responsible for the carrier's injuries regardless of whether the animal had ever bitten anyone before.

The Rising Cost of a Dog Bite in Illinois: What USPS Workers and Victims Face
Dog bite injuries are among the most expensive personal injury claims in homeowners insurance. According to the Insurance Information Institute and State Farm, insurers paid out $1.57 billion nationwide in 2024 across 22,658 claims, both figures representing all-time records. The average cost per claim has risen 86.1% over the past decade.
In Illinois, the financial exposure is even higher. The state recorded 837 dog bite claims in 2023 with total payouts exceeding $61.8 million. At $73,797 per claim, Illinois payout averages ranked among the highest in the country. The gap between Illinois and the national average exists largely because Illinois is a strict liability state: dog owners cannot argue that they did not know their animal was dangerous, which removes one of the primary defenses that reduce payouts in other jurisdictions.
For mail carriers specifically, the financial consequences extend beyond the dog owner's insurance. The medical bills after a dog bite can accumulate quickly: emergency treatment, potential surgery, infection management, and lost work time during recovery. The average hospitalization cost for a dog bite is approximately $18,200, nearly 50% more than for other acute injuries.
Illinois Strict Liability in Dog Bite Cases: What Carriers and Dog Owners Need to Know
Illinois is a strict liability state for dog bites under the Animal Control Act (510 ILCS 5/16). Dog owners are legally responsible for injuries caused by their animals regardless of whether the dog had any prior history of aggression. There is no "one bite" rule in Illinois. If a mail carrier is attacked while lawfully delivering mail, the dog's owner is liable for all resulting damages as long as the carrier did not provoke the animal.
This is directly relevant to postal worker cases. A letter carrier walking up to a front door to deliver mail is unquestionably in a place they have a legal right to be. The carrier has not provoked the dog. Both conditions for strict liability are satisfied in virtually every mail carrier attack. That makes these cases straightforward from a legal standpoint, and it is one reason Illinois's average claim payout is so much higher than the national average.
Illinois law also requires mandatory reporting. Under 510 ILCS 5/13, when an animal bites someone, the owner must have it examined by a veterinarian within 24 hours. Healthcare providers who treat bite wounds are separately required to report the incident to the local health department. There is no damage cap for personal injury claims in Illinois, meaning victims can pursue full compensation for medical expenses, lost wages, pain and suffering, and emotional distress. One of Briskman Briskman & Greenberg's Chicago personal injury lawyers can advise you on the best course of action based on the details of your case.
What to Do If a Dog Attacks You While Delivering or Receiving Mail
Carriers are trained to defend themselves, but prevention remains the most effective strategy. USPS employees carry dog repellent and are trained to use their mail satchels as barriers. A dog alert feature on handheld scanners warns carriers of known hazards on their routes. Despite these precautions, more than 6,000 attacks still occurred in 2024.
The single most effective prevention measure is for dog owners to keep their animals secured during delivery hours. Many of the attacks documented by the USPS involved dogs whose owners said the animal had never bitten anyone before. Under Illinois law, that history is irrelevant. The owner is liable from the first bite, and the scarring and long-term consequences of a dog bite can affect a victim for years.
