A dog bite is a bite upon a person or other animal by a dog. More than one successive bite is often called a dog attack, although dog attacks can include knock-downs and scratches. Though some dog bites do not result in injury, they can result in infection, disfigurement, temporary or permanent disability, or death. Another type of dog bite is the "soft bite" displayed by well-trained dogs, by puppies, and in non-aggressive play. [1] Dog bites can occur during dog fighting, as a response to mistreatment, by trained dogs working as guard, police or military animals, or during a random encounter. [2] [3]
There is debate on whether or not certain breeds of dogs are inherently more prone to commit attacks causing serious injury (i.e., so driven by instinct and breeding that, under certain circumstances, they are exceedingly likely to attempt or commit dangerous attacks). [4] It is recognized that the risk of dog bites can be increased by human actions such as abuse or bite training, or through inaction such as neglect, carelessness in confinement or lack of control.
Significant dog bites affect tens of millions of people globally each year. [5] It is estimated that 2% of the U.S. population, 4.5–4.7 million people, are bitten by dogs each year. [6] Most bites occur in children, [7] with nearly half of all children in the U.S. being bitten by a dog at least once by the age of 12. [8] In the 1980s and 1990s, the U.S. averaged 17 deaths per year. [9] Between 2011 and 2021 approximately 468 people were killed by dog bites in the United States, averaging 43 deaths per year. [10] Between 2018 and 2021, deaths were more than doubled for both males (age 15 to 37) and females (age 20 to 44). [11] Animal bites, most of which are from dogs, are the reason for 1% of visits to emergency departments in the United States. [7]
All dog breeds can inflict a bite; breed is not an accurate predictor of whether or not a dog will bite. [12] In the US pit bull-type and Rottweilers most frequently are identified breeds in cases of severe bites. [7] [12] In a study comparing media accounts of 256 dog bite related deaths 2000–2009, when a strict definition was used ("documented pedigree, parentage information, or DNA test results or on the basis of concordance among media breed descriptor, animal control breed descriptor, and the veterinarian-assigned breed from a photograph") the resulting 45 dogs comprised 20 recognized breeds and 2 known crosses. The study also published information comparing when multiple media reports (or media reports compared with animal control reports) differed in reporting the breeds. When using a strict definition ("Rottweiler" is not equal to "Rottweiler-mix") 30%-40% of the reports varied. When using a less strict definition ("Rottweiler" and "Rottweiler-mix" are equal enough) only 12%-15% of the reports varied. [13] [ non sequitur ]
A 2000 study by the Centers for Disease Control and Prevention (CDC) of human fatalities from dog bites during the twenty years 1979–1998, reported that pit bull-type dogs and Rottweilers were involved in more than half of the deaths. [9] Published in the Journal of the American Veterinary Medical Association, the AVMA's opinion was that the study could not be used to infer any breed-specific risk for dog bite fatalities without also noting the numbers of each breed residing in the US. [14]
In isolation, predatory behaviors are rarely the cause of an attack on a human. [15] Predatory aggression is more commonly involved as a contributing factor for example in attacks by multiple dogs; a "pack kill instinct" may arise if multiple dogs are involved in an attack. [16] [17]
Dog bite prevention is efforts to prevent people being attacked and bitten by dogs. Legislative bodies have addressed concerns about dog bites that include licensing laws, statutes outlawing organized dogfights, and leash laws. Breed-Specific Legislation (BSL) has been enacted in some areas limiting the ownership and activities of dogs perceived to be more likely to bite and attack. [19] [20] [21] [22] Dog breeds targeted by breed-specific regulations include Rottweilers, American Staffordshire Bull Terriers ("Pit Bulls"), Chow Chows, German Shepherd Dogs, and Doberman Pinschers. Other measures in preventing dog bites are Beware of the dog signage and locked dog enclosures. [2]
Some people, like the very young or the very old, are more susceptible to being bitten and therefore may need additional methods of prevention. [23] [24]
Dogs can be extremely territorial and protective. Dogs can attack anyone who poses a threat to their companions, whether humans, other dogs, or even cats. Dogs can rival bears and big cats in ferocity when confronting burglars, even if they are ordinarily docile.
In addition to causing pain, injury, or nerve damage, almost one out of five bites becomes infected. Those who work and live around dogs should be aware of the risk and take precautions. [23] Rabies is a particular risk associated with dog bites. In the United States between 16,000 and 39,000 people come in contact with potentially rabid dogs and other animals and receive rabies pre- and post-exposure prophylaxis against the rabies virus each year. [25] Because anyone who is bitten by an unvaccinated dog is at risk of getting rabies, local animal control agencies or police are sometimes able to capture the animal and determine whether or not it is infected with rabies. [23]
Identifying the risk of being bitten by a dog can prevent an attack and subsequent injury or death. Infants and children are more likely to be bitten. Small children can be attacked if they approach or play with a dog when they are not supervised. Among children, the rate of dog-bite–related injuries is highest for those five to nine years old. Children are more likely than adults to need medical attention for dog bites. Men are more likely than women to be bitten by a dog. Over half of dog-bite injuries occur in the home. Having a dog in the household is associated with a higher likelihood of being bitten than not having a dog. As the number of dogs in the home increases, so does the likelihood of being bitten. Adults with two or more dogs in the household are five times more likely to be bitten than those living without dogs at home. [23] [24]
The behavior of a dog may not always indicate its friendliness or unlikelihood of biting. This is because when a dog wags its tail, most people interpret this as the dog expressing happiness and friendliness. Though indeed tail wagging can express these positive emotions, tail wagging is also an indication of fear, insecurity, anxiety, challenging of dominance, establishing social relationships or a warning that the dog may bite. [26]
Rabies results in the death of approximately 55,000 people per year, with most of the causes due to dog bites. [5] Capnocytophaga canimorsus , MRSA, tetanus, and Pasteurella can be transmitted from a dog to someone bitten by the dog. [27] Bergeyella zoohelcum is an emerging infection transmitted through dog bites. [28] Infection with B. zoohelcum from dog bites can lead to bacteremia. [29]
When a person receives a dog bite where the skin is broken, the risk of a serious infection can be reduced by cleaning the wound and getting appropriate health care treatment. [30] It is important to find out if the dog's rabies vaccinations are current. [23] A Cochrane review found that there is not much evidence for or against current practices of keeping dog bite wounds left open to heal for a short time before closure (delayed closure) or not stitched at all (no closure) over immediate closure by stitching. [31]
Significant dog bites affect tens of millions of people globally each year. [5] It is estimated that 1.5–2 percent of the US population, from 4.5 to 4.7 million people, are bitten by dogs yearly. [32] [6] Most bites occur in children. [7] Over half of dog bite injuries occur at home with familiar dogs and having a dog in the household is linked to a higher likelihood of being bitten than not having a dog. As the number of dogs in the home increases, so does the likelihood of being bitten. [33] Dog bites may transmit zoonotic infections, which may also result in illness or death. Dogs are the primary source of rabies transmission to humans. [34] Information on the extent of traumatic injuries from dog attacks is incomplete, and the number of bites is thought to be underreported. [35] [36] [37] In a survey of dog bites in Pennsylvania, the rate of dog bites was 36 times higher than what had been reported to authorities. [38] [37] According to national estimates, almost 1,000 persons per day are seen in US emergency departments for dog bites. [37] [39] It has been estimated that 1 out of 2 people will sustain a dog-related injury during his lifetime. [40] [37] Most victims are involved in normal, apparently nonprovoking activities before dog attacks. [41] [42] [43]
Animal bites, most of which are from dogs, are the reason for 1% of visits to an emergency department in the United States. [7] Some people, like the very young or the very old are more susceptible to being bitten by a dog. [24] From 1979 through 1994 there were approximately 279 deaths related to dog attacks in the United States. [44]
More serious injuries from dogs are often described in the media. [45] [2] In 2010, more people were killed by dogs (34) than were hit by lightning (29). [46] [47] Emergency department visits and treatment by those bitten number in the thousands. [48]
On average 2,061 people received treatment for dog bite injuries each year between 2001 and 2013. [49]
About 5,900 Austrians are treated annually after being bitten by dogs. One fifth of those injured are children. [50]
In the United States, approximately 4.5 million people are bitten by dogs each year. Approximately twenty percent of dog bites become infected. [23]
In a survey of dog bites in Pennsylvania, the rate of dog bites was 36 times higher than what had been reported to authorities. According to national estimates, almost 1,000 persons per day are seen in emergency departments for dog bites. It has been estimated that 1 out of 2 people will have a dog-related injury during their lifetime. [37]

Dog owners may be legally liable for the bites and injuries that their dog causes to people or other dogs. In addition, states and local governments have passed laws and ordinances that allow the government to take action against dogs that are considered dangerous. [51] [52] [53] [54] In some cases, a dog owner may be criminally prosecuted for a dog attack on another person. [55] [56] Homeowner's insurance policies typically provide some liability coverage for dog bites that occur on the insured properties.
All US states recognize that a dog owner may be potentially liable for dog bites. Depending upon the state, the rules for when a dog owner may be liable for a bite will vary. Models of liability for dog bites fall into three broad categories:
The United States is not receptive to the idea that the dog itself can be criminally liable for a bite. [57] A California court explained that, although the tendency to anthropomorphize animals is understandable, especially with beloved pets like dogs, the law does not recognize dogs as having the mental state that can incur criminal liability. That is, although dogs and other animals may have the capacity to commit vicious and violent acts, they do not possess the legal ability to commit crimes. [58]
States that have enacted legislation that assigns liability include Michigan, [59] Rhode Island, [60] Florida, [61] California, [62] [63] and Texas. [54]
Connecticut's dog bite statute provides for strict liability in most situations, subject to exceptions if the person bitten by the dog was trespassing or involved in a tort, or was teasing, abusing, or tormenting the dog. [64] [65]
Pit bull is an umbrella term for several types of dog believed to have descended from bull and terriers. In the United States, the term is usually considered to include the American Pit Bull Terrier, American Staffordshire Terrier, American Bully, Staffordshire Bull Terrier, and sometimes the American Bulldog, along with any crossbred dog that shares certain physical characteristics with these breeds. In other countries, including the United Kingdom, the term is used as an abbreviation of the American Pit Bull Terrier breed specifically, while the Staffordshire Bull Terrier is not considered a pit bull. Most pit bull–type dogs descend from the British bull and terrier, a 19th-century dog-fighting type developed from crosses between the Old English Bulldog and the Old English Terrier.
In law, breed-specific legislation (BSL) is a type of law that prohibits or restricts particular breeds or types of dog. Such laws range from outright bans on the possession of these dogs, to restrictions and conditions on ownership, and often establishes a legal presumption that such dogs are dangerous or vicious to prevent dog attacks. Some jurisdictions have enacted breed-specific legislation in response to a number of fatalities or maulings involving pit bull–type dogs or other dog breeds commonly used in dog fighting, and some government organizations such as the United States Army and Marine Corps have taken administrative action as well. Due to opposition to such laws in the United States, anti-BSL laws have been passed in 21 of the 50 state-level governments, prohibiting or restricting the ability of jurisdictions within those states to enact or enforce breed-specific legislation.
The American Pit Bull Terrier (APBT) is a dog breed recognized by the United Kennel Club (UKC) and the American Dog Breeders Association (ADBA), but not the American Kennel Club (AKC). It is a medium-sized, short-haired dog, of a solid build, whose early ancestors came from England. When compared with the English Staffordshire Bull Terrier, the American Pit Bull Terrier is larger by margins of 6–8 inches (15–20 cm) in height and 25–35 pounds (11–16 kg) in weight. The American Pit Bull Terrier varies in size: males are normally about 18–21 inches (45–53 cm) in height and around 35–60 pounds (15–27 kg) in weight, while females are normally around 17–20 inches (43–50 cm) in height and 30–50 pounds (13–22 kg) in weight.
An animal bite is a wound, usually a puncture or laceration, caused by the teeth. An animal bite usually results in a break in the skin but also includes contusions from the excessive pressure on body tissue from the bite. The contusions can occur without a break in the skin. Bites can be provoked or unprovoked. Other bite attacks may be apparently unprovoked. Biting is a physical action not only describing an attack but it is a normal response in an animal as it eats, carries objects, softens and prepares food for its young, removes ectoparasites from its body surface, removes plant seeds attached to its fur or hair, scratching itself, and grooming other animals. Animal bites often result in serious infections and mortality. Animal bites not only include injuries from the teeth of reptiles, mammals, but fish, and amphibians. Arthropods can also bite and leave injuries.
The Dobermann is a German breed of medium-large working dog of pinscher type. It was originally bred in Thuringia in about 1890 by Louis Dobermann, a tax collector. It has a long muzzle and – ideally – an even and graceful gait. The ears were traditionally cropped and the tail docked, practices which are now illegal in many countries.
The health of dogs is a well studied area in veterinary medicine.
The dog is a domesticated descendant of the wolf. Also called the domestic dog, it was selectively bred from an extinct population of wolves during the Late Pleistocene by hunter-gatherers. The dog was the first species to be domesticated by humans, over 14,000 years ago and before the development of agriculture. Experts estimate that due to their long association with humans, dogs have gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.
Rabies is a viral disease that causes encephalitis in humans and other mammals. It was historically referred to as hydrophobia because its victims would panic when offered liquids to drink. Early symptoms can include fever and abnormal sensations at the site of exposure. These symptoms are followed by one or more of the following symptoms: nausea, vomiting, violent movements, uncontrolled excitement, fear of water, an inability to move parts of the body, confusion, and loss of consciousness. Once symptoms appear, the result is virtually always death. The time period between contracting the disease and the start of symptoms is usually one to three months but can vary from less than one week to more than one year. The time depends on the distance the virus must travel along peripheral nerves to reach the central nervous system.
The prevalence of rabies, a deadly viral disease affecting mammals, varies significantly across regions worldwide, posing a persistent public health problem.
In animals, rabies is a viral zoonotic neuro-invasive disease which causes inflammation in the brain and is usually fatal. Rabies, caused by the rabies virus, primarily infects mammals. In the laboratory it has been found that birds can be infected, as well as cell cultures from birds, reptiles and insects. The brains of animals with rabies deteriorate. As a result, they tend to behave bizarrely and often aggressively, increasing the chances that they will bite another animal or a person and transmit the disease.
Fatal dog attacks in the United States cause the deaths of thirty to fifty people each year. According to the National Center for Health Statistics, there were 468 deaths in the United States from being bitten or struck by a dog between 2011 and 2021. This is an average of 43 deaths annually, ranging from a low of 31 deaths in 2016 and a high of 81 deaths in 2021. Dogs killed more males than females during the tracking decade. Children between the ages of one to four are most often the victims, accounting for 29.4% of the fatalities from dog attacks in 2022; those under the age of seventeen accounted for 56.7% of all fatalities that year.
Dogs in the United States have significant popularity and status – they are often treated as family members. Currently, the American Kennel Club is the largest registry of pure breed dogs across the world.
Animal attacks are violent attacks caused by non-human animals against humans, one of the most common being bites. These attacks are a cause of human injuries and fatalities worldwide. According to the 2012 U.S. Pet Ownership & Demographics Sourcebook, 56% of United States citizens owned a pet. In the United States in 1994, approximately 4.7 million people were bitten by dogs. The frequency of animal attacks varies with geographical location, as well as hormonal secretion. Gonad glands found on the anterior side of the pituitary gland secrete androgen and estrogen hormones. Animals with high levels of these hormones, which depending on the species can be a seasonal occurrence, such as during rutting season, tend to be more aggressive, which leads to a higher frequency of attacks not only to humans but among themselves. In the United States, a person is more likely to be killed by a domesticated dog than they are to die from being hit by lightning according to the National Safety Council.
Rabies is a viral disease that exists in Haiti and throughout the world. It often causes fatal inflammation of the brain in humans and other mammals, such as dogs and mongooses in Haiti. The term "rabies" is derived from a Latin word that means "to rage"; rabid animals sometimes appear to be angry. Early symptoms can include fever and tingling at the site of exposure, followed by one or more of the following symptoms: violent movements, uncontrolled excitement, fear of water, an inability to move parts of the body, confusion, and loss of consciousness. Once symptoms appear, death is nearly always the outcome. The time period between contracting the disease and showing symptoms is usually one to three months; however, this time period can vary from less than a week to more than a year. The time between contraction and the onset of symptoms is dependent on the distance the virus must travel to reach the central nervous system.
Cat bites are bites inflicted upon humans, other cats, and other animals by the domestic cat. Data from the United States show that cat bites represent between 5–15% of all animal bites inflicted to humans, but it has been argued that this figure could be the consequence of under-reporting as bites made by cats are considered by some to be unimportant. Though uncommon, cat bites can sometimes transmit rabies, cause health complications, and even, though very rarely, lead to death.
A monkey bite is the bite of a monkey and is the second most common animal bite after dog bites in India. Monkey bites account for 2–21% of animal bite injuries. Monkey bites are an important risk among travelers and after dog bites is the most common animal bite for travelers. Treatment depends upon many factors including the suspicion of rabies.

DogsBite.org is a nonprofit organization that publishes accounts of and compiles statistics of dog bite related fatalities throughout the United States, victim testimonies, an overview of breed-specific legislation within the United States, and advocates for victims of dog bites by promoting breed-specific legislation as a means to reduce serious dog attacks. The organization provides statistics and information to news organizations and has filed amicus briefs in court cases related to breed-specific legislation. The organization has been criticized for publishing misleading or inaccurate information.
Fatal dog attacks are human victim's deaths caused by dogs. The study of fatal dog attacks can lead to prevention techniques which can help to reduce all dog bite injuries, not only fatalities. Dog bites and attacks can result in pain, bruising, wounds, bleeding, soft tissue injury, broken bones, loss of limbs, scalping, disfigurement, life-threatening injuries, and death.
The Sarawak rabies outbreak is an ongoing rabies outbreak in the state of Sarawak in Malaysia. Until 6 December 2022, 49 confirmed rabies cases and 44 deaths have been reported.
Incredibly, nearly half of all American kids have been bitten by the age of 12.
An Albanian town had to call in police and hunters after a pack of 200 stray mountain dogs attacked at least nine people. Headed by a clearly identifiable leader, the snarling pack overran the main street of the small northern town of Mamurras, its mayor said on Wednesday. "Even in the movies I have never seen a horde of 200 stray dogs from the mountains attacking people in the middle of a town," Anton Frroku said on Wednesday. He said the dogs bit at least nine people, aged from 20 to 60, dragging them to the ground and inflicting serious wounds.
