Fatal Dog Attacks in the United States

fatal dog attacks
Fatal dog attacks remain a challenging public health problem in the USA. About 30-40 people in the USA are killed annually by dogs.

The task of providing readers my readers with verifiable and accurate  statistics on fatal dog attacks in the USA is a time-consuming task.  Moreover, collecting stats on fatal dog attacks is not as meaningful as it once was. Why? Because the epidemiology and statistics about fatal dog attacks remain approximately the same from year-to-year. Hence, fatal dog attack statistics in USA for 2019 – as presented below – will be the final year in which information of this kind will be published on

Annual statistics basically show that about 30-40 fatalities occur each year. The vast majority of victims are the elderly or young. An unsupervised male pit bull type dog is the kind of dog usually implicated. And the incident usually happens near where the dog lives.

Moreover, collecting additional statistics on a yearly basis is of limited value. Such statistics do not further  enhance an understanding of how animal behavior factors motivate a dog to kill a person. For example, how does having knowledge about who was killed, the name of the person, the circumstances of such, viewing the photo the victim published on a website, etc. help with the prevention of future fatal dog attacks?  Probably not much. Nonetheless, we all must realize that each incident must be unspeakably tragic for family members and friends of the victim!!

For students doing research on fatal dog attacks, visit Wikipedia for trustworthy epidemiological findings. However, be critical about the information found on other websites. This information may be misleading, particularly on websites written by individuals who have a strong negative bias against pit bulls

2019 statistics – Summary of findings

Fourty-eight (48) people were fatally killed by dogs in 2019. Most of the victims were children or the elderly and in almost all instances the victim was alone when the incident happened. Many of the incidences happened in the “territory” of the dog or shortly after the dog(s) escaped from the property in which the dog was living. A surprisingly high number people were killed by a dog a “family” dog. 

Various breeds were involved, but mostly pit-bull type dogs, although there were fatalities involving Coonhounds, Rottweilers and even an attack-trained Belgian malinois. The majority of the incidents happened when the dogs were acting together as a pack.[1]The estimated number people bitten by dogs in the United States in 2019, and not necessarily killed, did not change markedly despite the abundance of information about dog bite safety available on … Continue reading.

Are pit bulls inherently dangerous?

Granted, pit bull type dogs have likely been implicated in a disproportional number of fatal dog attacks on people. However, this should not be taken to mean that every pit bull or pit bull type dog has the temperament or inclinations to kill a personEvery dog, regardless of breed, must be be judged on its own merits.  How it is maintained, controlled properly, past bite history, etc.  Tremendous individual differences exists between pit bull type dogs. This belief has been stated many times by many animal behavior experts but it is worth repeating again to discredit the nonsense that all pit bulls are naturally dangerous.

Are attack-trained police canines more dangerous than pit bulls?

Certainly, some pit bulls type dogs pose an extreme danger to public safety and in certain circumstances can readily kill a person. However, there are other breeds potentially as dangerous as some pit bulls. For example, I would rank an attack-trained police K9 equally as dangerous, particularly when the K-9 handler loses control over his dog.  And, not surprisingly, there are many anecdotal examples in which this has happened. These instances usually lead to severe dog bite injury inflicted onto the victim by the attack-trained police K-9, but usually not to a fatality.

Concerns about false or misleading information on other websites

  • Second, the accuracy of data on fatal dog attacks depends on the validity and accuracy of facts about the incident as reported in news stories by the journalists who write the stories.  Website authors depend on this information to create the content on their sites, yet the extent to which the information published is independently verified remains dubious.  Generally, the information is taking on face value. This may be problematic for a number of reasons. Particularly significant is the information reported about the breed of dog involved.  Occasionally, mistakes in correctly identifying the breed of dog(s) involved in a fatal attack happen (see problems with pit bull terrier identification). Likewise, other data collection techniques (animal control reports, police reports, witness observation) used for breed identification purposes in fatal dogs attack investigations may  be flawed because of problems inherent with accurate breed identification through visual means.
  • Third, because breed identity may be mistaken, the numbers may be inflated for certain dogs, such as pit bull dogs. That it is a mastiff-type dog was implicated in incident but mistakenly identified as pit bull.
  • Fourth, it is important to note that a pit bull is not a breed of dog.  Instead, the term “pit bull” only describes a dog that has an appearance similar to a American Pit Bull terrier or American Staffordshire terrier.   In some cases a dog identified as a pit bull, based on its physical appearance, may be genetically similar to the American Staffordshire Terrier (AKC recognized) or an American Pit Bull (UKC recognized), but in other cases the dog is genetically dissimilar.

  • Fifth, the reader should note the incidences of fatalities listed on any website may not represent every case in the United States where death was caused by a dog attack. It is conceivable that some fatal dog attacks in the United States go unreported and never make news headlines, particularly in rural areas.
  • Sixth, the fatalities reported on many websites may not be a direct result of injuries sustained from a dog attack.For example, in some dog bite fatalities the primary cause of death is secondary to bite injuries caused by an attack.  Examples include caradic arrest, freezing to death after falling unconscious following an attack, rabies, septicaemia, infection or falling on head as a result of being attacked. I recall a reported incident in March 2010 incident in Lucknow, South Carolina involving a 65-year-old lady.  Several websites reported this as a dog bite fatality caused by a pit bull attack, but subsequently the autopsy indicated a fatal heart attack was the primary cause of death (presumably from the stress of the attack). Also, note that a human fatality can be caused by the behavior of a dog that does not involve aggressive intent (e.g. smothering). Click here for medical perspective on the causes of death as a direct result of the dog attack.
