Dog bite statistics
Dog bites and other dog-related injuries accounted for more than one-third of all homeowners insurance liability claim dollars paid out in 2016, costing more than $600 million.
In 2016, dogs attacked over 6,750 U.S. Postal Service employees -- over 200 more attacks than last year. The city of Los Angeles had the most attacks (80).
Approximately 4.5 million dog bites occur each year in the United States. Nearly 1 out of 5 bites becomes infected.
In 2015, more than 28,000 people underwent reconstructive surgery as a result of being bitten by dogs.
There was an 86% increase in dog bite-related hospitalization stays between 1993 and 2008 in the United States.
The average cost of a dog bite-related hospital stay was $18,200, about 50% higher than the average injury-related hospital stay.
There were 4 times as many dog bite-related ED visits and 3 times as many hospital stays in rural areas than in urban areas in 2008.
In 2008, Medicare and Medicaid combined paid for 37% of all dog bite-related hospitalization stays in the United States.
Adults with two or more dogs in the household are five times more likely to be bitten than those living without dogs in the home.
Dog bites occur every 75 seconds in the United States. Each day, over 1,000 citizens need emergency medical care to treat these injuries.
Dog attack victims suffer over $1 billion in monetary losses annually. JAMA reports this estimate to be as high as $2 billion.
Severe dog bite injury statistics
Our data were consistent with others, in that an operative intervention was more than 3 times as likely to be associated with a pit bull injury than with any other breed.
Our data revealed that pit bull breeds were more than 2.5 times as likely as other breeds to bite in multiple anatomical locations.
Most alarming is the observation that when attacks come from unfamiliar dogs, the pit bull was responsible for 60% and 63% of all injuries and ocular injuries, respectively.

Of the more than 8 different breeds identified, one-third were caused by pit bull terriers and resulted in the highest rate of consultation (94%) and had 5 times the relative rate of surgical intervention.
Unlike all other breeds, pit bull terriers were relatively more likely to attack an unknown individual (+31%), and without provocation (+48%).
Although a number of dog breeds were identified, the largest group were pit bull terriers, whose resultant injuries were more severe and resulted from unprovoked, unknown dogs.
In this series, dogs causing the injury were overwhelmingly familiar with the patient: 53% of dogs belonged to the family ... In our series (as in Philadelphia), Pit bulls were most commonly responsible.
Attacks by pit bulls are associated with higher morbidity rates, higher hospital charges, and a higher risk of death than are attacks by other breeds of dogs.
Dog bite-related fatality statistics
In 2016, pit bulls accounted for 71% of all deaths, just over 7 times more than the next closest dog breed.
In 2016, family dogs inflicted 45% of all dog bite fatalities. Family pit bulls accounted for 86% of these deaths.
In 2016, 42%, of all dog bite fatality victims were either visiting or living temporarily with the dog's owner when the fatal attack occurred.
In the 12-year period of 2005 to 2016, pit bulls mauled to death 254 Americans, about one citizen every 17 days.
In the 12-year period of 2005 to 2016, two dog breeds accounted for 76% of the attacks that resulted in death: pit bulls and rottweilers.
From 2005 to 2016, 46% of all fatal attacks involved more than one dog. Attacks involving pit bulls contributed to 72% of these deaths.
From 2005 to 2016, only 20% of all deaths resulted in criminal charges. Pit bulls accounted for 74% of these criminal cases.
By 2020, pit bulls are projected to maul 385 Americans to death since 1998, the year the CDC stopped tracking fatal dog attacks by breed.
In 2015, Pit bulls contributed to 82% (28) of the total recorded deaths, the highest fatality count on record for the breed.
In 2015, the combination of pit bulls and rottweilers contributed to 91% of all dog bite-related fatalities.
In 2015, 9% of the attacks resulting in death were inflicted by dogs rehomed by county operated shelters or rescues.
2015 marked the first time a medical examiner ruled "suicide" as the manner of death in a fatal dog mauling.
In 2014, loose dogs off their owner's property inflicted 40% of all fatal attacks, a sharp rise from the 10-year average of 24% (2005 to 2014).
In the 3-year period of 2006 to 2008, 18% of all fatal dog attacks occurred off the owner's property. Pit bulls accounted for 81% of these deaths.
In 2012, "rescue" dogs accounted for 15% (6) of all deadly attacks. Of the adults killed, 3 females, each were killed by their own rescue dog.
In the first eight months of 2011, nearly half of the persons killed by a pit bull was the dog's owner and primary caretaker.
In 2011, adult victims of fatal pit bull maulings more than doubled the number of child victims.
The data indicate that rottweilers and pit bull-type dogs accounted for 67% of human DBRF in the United States between 1997 and 1998. It is extremely unlikely that they accounted for anywhere near 60% of dogs in the United States during that same period and, thus, there appears to be a breed-specific problem with fatalities.

Breed-specific law statistics
Over 1,000 U.S. cities have adopted breed-specific laws since the mid 1980s, just after pit bulls (fighting dogs) began leaking into the general population.
Over 290 U.S. military bases governed by the U.S. Air Force, Air Force Space Command, U.S. Army, U.S. Marine Corps and Navy regulate dangerous dog breeds.
Over 40 countries across the world -- or parts within these countries -- regulate dangerous dog breeds with breed-specific laws.
