A Dog bite is a bite inflicted upon a person, a group of persons or another animal by a dog. One or more successive bites is often considered a dog attack. Though the majority of dog bites do not result in injury, disfigurement, infection or permanent disability, those that do are documented by the Centers for Disease Control and Prevention and hospital emergency rooms. Another type of dog bite is the 'soft bite' displayed by well-trained dogs, puppies and in non-aggressive play. Situations in which dog bites occur include dog fighting, mistreatment, trained dogs acting as guard or military animals, provoked or unprovoked.

Epidemiology
Significant dog bites affect tens of millions of people globally each year. It is estimated that 1.5 - 2 percent of the US population, from 4.5-4.7 million people, are bitten by dogs yearly. Pit bulls bit and killed 21 people during the 1980s. Most bites occur in children. In the 1980s and 1990s the US averaged 17 fatalities per year, while in the 2000s this has increased to 26. 77% of dog bites are from the pet of family or friends, and 50% of attacks occur on the dog owner's property. Animal bites, most of which are from dogs, are the reason for 1% of visits to an emergency department in the United States. Young children are sustain bites by familiar or family dogs during normal activities. Some people, like the very young or the very old are more susceptible to being bitten by a dog. More serious injuries from dogs are often described in the media. In 2010, more people were killed by dogs (34) than were hit by lightening (29). Emergency room visits and treatment by those bitten number in the thousands.
In a study of 1616 dog attacks treated by the emergency room staff at Children's Healthcare of Atlanta, 58% of all pediatric patients bitten by dogs needed treatment for lacerations and 5.5% of all those treated required an operation to make repairs. Very young children (infants) were more than six times more likely to bitten by a family pet and over six times more likely to sustain injuries in their neck and head. Children aged five and younger needed treatment and repair 62% of the time. Those dogs identified as Pit bulls were implicated in 50% of the bites needing surgical treatment of the child. Dogs identified as pit bulls were more likely to make multiple bites in different body areas of the children.

Health effects
Rabies results in the death of approximately 55,000 people a year, with most of the causes due to dog bites. Capnocytophaga canimorsus, MRSA, Tetanus, and Pasteurella can be transmitted from a dog to someone bitten by the dog. Bergeyella zoohelcum is an emerging infection transmitted through dog bites. Infection with B.zoohelcum from dog bites can lead to bacteremia.
Causes
Even without provocation, some dogs will bite.
Reducing the risk of bites
The human-dog relationship is based on unconditional trust; however if this trust is lost it will be difficult to reinstate. As a last resort, humans will use a slap but a dog will use a bite. A dog's thick fur protects it to some degree from the bite of another dog.
Human activities may increase the risk of a dog bite as does age, height, and movement. The CDC and the American Veterinary Medical Association have published recommendations which encourage those that are around dogs to:
- not approach an unfamiliar dog.
- not run from a dog.
- Remain motionless when approached by an unfamiliar dog.
- Curl into a ball, while protecting your head and ears if knocked over.
- not panic or make loud noises.
- Report dogs that are behaving strangely.
- Disturb a dog that is caring for puppies.
- not pet a strange dog
- not encourage your dog to play aggressively.
- not small children play with a dog unsupervised.
- Avoid the family dog if it is ill
- Avoid waking the dog, call the dog by name
- Avoid retrieving objects from the dog's mouth
- Avoid face-to-face interaction with the dog
- not disturb the dog while the animal is eating.
- reduce the dog's interaction with children
- not attempt to break up a dog fight.
Dog behavior
In isolation, predatory behaviors are rarely the cause of an attack on a human. 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.
Breeds
All dog breeds can inflict a bite. Breed is not accurate predictor of whether or not will bite. In the US pit bull-type and Rottweilers most frequently are identified breeds in cases of severe bites. This may be due to their size. These breeds are more frequently owned by people involved in crime.
from 2000 to 2009, media accounts were compared with reports available from animal control officials. It was determined that in a sample of 256 dog bite related fatalities, breed could only be validly determined in 45 cases, and the attacks in these 45 cases were dispersed among 20 different breeds and 2 known mixes. For a further set of 401 dogs in media accounts of dog bite related fatalities, breed determination differed between different media accounts of the same attack 31% of the time, factoring in animal control accounts produced disagreement on breed for 40% of attacks.
A 2000 study by the US by the Centers for Disease Control and Prevention (CDC) reports of 327 people killed by dogs "pit bull terrier" or mixes thereof were reportedly involved in 76 cases. The breed with the next-highest number of attributed fatalities was the Rottweiler and mixes thereof, with 44 fatalities. Pit bull-type dogs and Rottweilers are disproportionately more dangerous than other dog breeds, the American Veterinary Medical Association released a statement that this study "cannot be used to infer any breed specific risk for dog bite fatalities". These figures reporting certain breeds as being more prone to biting has found those to be the breeds in the greatest population where the dog bites are reported.
A 2015 study in Ireland found that dog bite injuries greatly increased since the introduction of legislation targeting specific dog breeds. This study also suggested that targeting dog breeds may actually contribute to increases in dog-bite hospitalisations through the reinforcing of incorrect stereotypes of risk being determined by breed. The study reported that as a result of targeting dog breeds, stereotypes of the dangerousness of certain breeds and assuming the safety of others simply due to their breed may result in people incorrectly interacting with dogs from both categories.
Treatment
Since an infection from a dog bite can occur, the risk of serious infection can be reduced by:
- Applying pressure on the bite with a clean, dry cloth to stop the bleeding.
- Calling 911 or other emergency services if the bleeding can't be stopped.
- Seeking treatment from a healthcare provider immediately
Local animal control agencies or police are sometimes able to capture the animal and determine whether or not it is infected with rabies. This is important if the dog appears sick or is acting strangely.
Prevention
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 cities, states and municipalities limiting the ownership and activities of dogs perceived to be more likely to bite and attack. This breed specific regulations are usually directed toward those animals perceived to be Rottweilers, American Staffordshire Bull Terriers ("Pit Bulls"), Chow Chows, German Shepherd Dogs, and Doberman Pinschers, "breeds traditionally known as 'dangerous,' or those that have demonstrated particular propensities for aggression and violent behavior". Though effective in reducing the number of bites and attacks from dogs, such prevention measures are often opposed by dog owners. To prevent dog bites, some regulations intend to make the owner liable for bites of their dogs.
Other measures in preventing dog bites are signage ("Beware of Dog") and locked dog enclosures. Dog owners often oppose protective regulations in the courts claiming either that the regulations will not prevent bites and attacks and/or their rights as dog owners are being infringed.
Controversy and legal issues
Austria
About 5,900 Austrians are treated annually after being bitten by dogs. One fifth of those injured are children.
United States
Controversy exists on whether or not certain breeds of dogs are more prone to bite than others. Although some research suggests that breed-specific legislation is not completely effective in preventing dog bites, efforts to establish regulations limiting dogs that bite is ongoing. The rights of animals is often in question. The targeting of specific dog breed creates stereotypes. This influences the perceived risk of sustaining a bite from a dog of a particular breed.
Dog owners are liable for the bites and injuries that their dog causes to people or other dogs. States that enact legislation that assigns liability are Michigan, Rhode Island, Florida, California, and Texas.
