As of May 25, 2013, the USA death count from dogs in 2013 is 14. Of these, 13 people were killed by pit bulls. In recent years, the dogs responsible for the bulk of the homicides are pit bulls and Rottweilers:
"Studies indicate that pit bull-type dogs were involved in approximately a third of human DBRF (i.e., dog bite related fatalities) reported during the 12-year period from 1981 through1992, and Rottweilers were responsible for about half of human DBRF reported during the 4 years from 1993 through 1996....[T]he 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." (Sacks JJ, Sinclair L, Gilchrist J, Golab GC, Lockwood R. Breeds of dogs involved in fatal human attacks in the United States between 1979 and 1998. JAVMA 2000;217:836-840.)
The Clifton study of attacks from 1982 through 2006 produced similar results. According to Clifton study, pit bulls, Rottweilers, Presa Canarios and their mixes were responsible for 65% of the canine homicides that occurred during a period of 24 years in the USA. (Clifton, Dog attack deaths and maimings, U.S. & Canada, September 1982 to November 13, 2006; click here to read it.)
Other breeds were also responsible for homicides, but to a much lesser extent. A 1997 study of dog bite fatalities in the years 1979 through 1996 revealed that the following breeds had killed one or more persons: pit bulls, Rottweilers, German shepherds, huskies, Alaskan malamutes, Doberman pinschers, chows, Great Danes, St. Bernards and Akitas. (Dog Bite Related Fatalities," Morbidity and Mortality Weekly Report, May 30, 1997, Vol. 46, No. 21, pp. 463 et. seq.) Since 1975, fatal attacks have been attributed to dogs from at least 30 breeds.
The most horrifying example of the lack of breed predictability is the October 2000 death of a 6-week-old baby, which was killed by her family's Pomeranian dog. The average weight of a Pomeranian is about 4 pounds, and they are not thought of as a dangerous breed. Note, however, that they were bred to be watchdogs! The baby's uncle left the infant and the dog on a bed while the uncle prepared her bottle in the kitchen. Upon his return, the dog was mauling the baby, who died shortly afterwards. ("Baby Girl Killed by Family Dog," Los Angeles Times, Monday, October 9, 2000, Home Edition, Metro Section, Page B-5.)
In Canine homicides and the dog bite epidemic: do not confuse them, it has been pointed out that the dog bite epidemic as a whole involves all dogs and all dog owners, not just the breeds most likely to kill. In all fairness, therefore, it must be noted that:
- Any dog, treated harshly or trained to attack, may bite a person. Any dog can be turned into a dangerous dog. The owner or handler most often is responsible for making a dog into something dangerous.
- An irresponsible owner or dog handler might create a situation that places another person in danger by a dog, without the dog itself being dangerous, as in the case of the Pomeranian that killed the infant (see above).
- Any individual dog may be a good, loving pet, even though its breed is considered to be potentially dangerous. A responsible owner can win the love and respect of a dog, no matter its breed. One cannot look at an individual dog, recognize its breed, and then state whether or not it is going to attack.
To learn more about dog attacks, see Why dogs bite people To learn about how to take some of the bite out of the dog bite epidemic, see Attorney Kenneth Phillips' 10-point plan for Preventing Dog Bites.
There have been many news reports about deaths caused by dogs in the USA. The attention given to the homicides has put the spotlight on pit bulls and Rottweilers. There is a very good reason for focusing on these two breeds: in recent years, they have usually been the number one and number two canine killers of humans. (See The breeds most likely to kill.) Furthermore, a recent study by hospital physicians also has established that 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. (Read the abstract.)
However, one must differentiate between canine homicides and dog bites. They are hardly the same. For the 30 to 35 canine homicides per year, there are more than 4.5 million bites, with 850,000 of the bite victims requiring medical attention. Pit bulls certainly do cause the worst bites and the highest number of homicides, but they and Rottweilers are not the cause of all dog bites. The dog bite epidemic involves all dogs and all dog owners. While pit bulls and Rottweilers inflict a disproportionate number of serious and even fatal injuries, the dog bite epidemic involves many different breeds, and results from many different causes.
To reduce dog bites, we must address all of the reasons for the epidemic. They include things like underfunding of animal control departments, and failure to educate children and dog owners. Efforts should not be limited to only banning breeds, or only reducing the population of breeds, or only increasing criminal penalties when dogs bite. The war on this epidemic must be comprehensive.

The number of dogs
There currently are 83.3 million dogs in the USA, which are kept by 56.7 million households. (American Pet Products Association, 2013-2014 APPA National Pet Owners Survey Statistics: Pet Ownership & Annual Expenses.)
The number of victims
The most recent USA survey of dog bites conducted by CDC researchers concluded that in 2001, 2002 and 2003 there were 4.5 million American dog bite victims per year (1.5% of the entire population). Sacks JJ, Kresnow M. Dog bites: still a problem? Injury Prevention 2008 Oct;14(5):296-301.
885,000 bites per year -- almost one out of every 5 -- are serious enough to require medical attention. (Centers for Disease Control, Dog Bites, accessed May 10, 2014.)
Dog bites send nearly 368,000 victims to hospital emergency departments per year (1,008 per day). Centers for Disease Control and Prevention, Nonfatal Dog Bite–Related Injuries Treated in Hospital Emergency Departments — United States, 2001, MMWR 2003;52:605-610.
In 2012, more than 27,000 people underwent reconstructive surgery as a result of being bitten by dogs. (Centers for Disease Control, Dog Bites, accessed May 10, 2014, quoting from American Society of Plastic Surgeons. 2012 Plastic Surgery Statistics Report [online]. 2012. [cited 2013 Oct 24]. Available from URL: http://www.plasticsurgery.org/Documents/news-resources/statistics/2012-Plastic-Surgery-Statistics/full-plastic-surgery-statistics-report.pdf.)
16,476 dog bites to persons aged 16 years or greater were work related in 2001. (Ibid., Nonfatal Dog Bite–Related Injuries Treated in Hospital Emergency Departments — United States, 2001, MMWR 2003;52:608.
Getting bitten by a dog is the fifth most frequent cause of visits to emergency rooms caused by activities common among children. (See Weiss HB, Friedman DI, Coben JH. Incidence of dog bite injuries treated in emergency departments, JAMA 1998;279:53; also see US Consumer Product Safety Commission, Injuries associated with selected sports and recreational equipment treated in hospital emergency departments, calendar year 1994. Consumer Product Safety Review, Summer 1996;1:5.) Note that this comparison is limited to activities that children more or less voluntarily engage in, such as playing sports, playing with animals, etc. Dog bite injuries are not specifically set forth in Federal Interagency Forum on Child and Family Statistics, Child Injury and Mortality, pp. 36, 37, 136 and 137, which states that the leading causes of emergency room visits overall are falls, being struck by or against an object, natural or environmental causes, poisening, being cut or pierced, and motor vehicle accident.
Dog bites have risen in number and severity since the 1980s
It appears clear that the number of dog bites as well as their severity has risen dramatically since the 1980s.
- There was a 36% increase in medically attended bites from 1986 to 1994. In 1986, 585,000 people required medical attention or restricted activity (Sosin DM, Sachs JJ, Sattin RW. Causes of nonfatal injuries in the United States, 1986. Accid. Anal. Prev. 1992;24:685-687) but by 1994 an estimated 800,000 sought medical care for bites. (Weiss HB, Friedman D, Coben JH. Incidence of dog bite injuries treated in emergency departments. JAMA 1998;279:51-53.)
- There was an 86% increase in hospitalizations because of dog bites from 1993 to 2008. The number went from 5,100 hospitalizations in 1993, to 9,500 in 2008. The average cost of treatment was $18,200 per patient. The patients generally were kids under 5 years old and seniors over 65. (US Dept. of Health and Human Services, Hospital Admissions for Dog Bites Increase 86 Percent Over a 16-Year Period, Dec. 1, 2010.)
- There was a 10% increase in emergency room visits for new dog bites from 1992 to 2001. From 1992 to 1994, there were 914 dog bite patients per day who were treated in emergency departments across the USA. (Weiss HB, Friedman D, Coben JH, Incidence of dog bite injuries treated in emergency departments. JAMA 1998;279:51-53.) The number increased to 1,008 per day by 2001. Centers for Disease Control and Prevention, Nonfatal Dog Bite–Related Injuries Treated in Hospital Emergency Departments — United States, 2001, MMWR 2003;52:605-610.
- There was an 82% increase in fatal dog attacks from the 1980s to 2012. The average number of canine homicides per year was 17 in the 1980s and 1990s (see below); it has risen to an average of over 31 human deaths per year since 2007, with the number reaching 37 in 2012. There were 33 fatalities in 2007, 23 in 2008, 30 in 2009, 34 in 2010, 31 in 2011, 37 in 2012 and 32 in 2013. (Kenneth M. Phillips, Canine Homicides, a section of Dangerous and Vicious Dogs, dogbitelaw.com, 2013.)
The number of human fatalities caused by dog bites is rising
The number of fatal dog attacks in the USA has been going up. The yearly average was 17 in the 1980s and 1990s; in the past 6 years, the average has been 31.
The yearly number of fatal dog attacks in the USA is variously reported as 12, 17 and 26, but this discrepency is caused by citing studies which took place in different years. It is most accurate to say that the average number was 17 in the 1980s and 1990s, and that it has risen to over 30 in this decade. The article mentioning 12 deaths per year was published by CDC as Dog-Bite-Related Fatalities -- United States, 1995-1996, MMWR 46(21):463-467, 1997. It related that there were 25 documented deaths in 1995 and 1996 (i.e., 12.5 per year), but a footnote said that the figure 25 probably represented only 75% of the actual number of dog bite related fatalities. This article nevertheless is the source of the oft-cited and misquoted statistic that there are only 12 deaths per year; the footnote is always ignored. This is especially puzzling because the same article cited two prior studies: Sacks JJ, Sattin RW, Bonzo SE. Dog bite-related fatalities from 1979 through 1988, JAMA 1989;262:1489-92, and Sacks JJ, Lockwood R, Hornreich J, Sattin RW. Fatal dog attacks, 1989-1994. Pediatrics 1996;97:891-5. Taken together, the three articles show that from 1979 to 1996, 304 people in the USA died from dog attacks, making the average number of deaths per year 17. Therefore, it is more accurate to summarize the publications as showing that the average number of deaths during the 18-year period of 1979 to 1996 was 17, despite the fact that the CDC itself routinely says the figure is 12, ignoring the footnote mentioned above.

The deadliest dogs
A review of 82 dog bite cases at a level 1 trauma center where the breed of dog was identified concludes that 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. Bini, John K. MD; Cohn, Stephen M. MD; Acosta, Shirley M. RN, BSN; McFarland, Marilyn J. RN, MS; Muir, Mark T. MD; Michalek, Joel E. PhD; for the TRISAT Clinical Trials Group, Mortality, Mauling, and Maiming by Vicious Dogs, Annals of Surgery (April 2011, Vol. 253, Issue 4, pp. 791–797).
Merritt Clifton, editor of Animal People, has conducted an unusually detailed study of dog bites from 1982 to the present. (Clifton, Dog attack deaths and maimings, U.S. & Canada, September 1982 to November 13, 2006; click here to read it.) The Clifton study show the number of serious canine-inflicted injuries by breed. The author's observations about the breeds and generally how to deal with the dangerous dog problem are enlightening. According to the Clifton study, pit bulls, Rottweilers, Presa Canarios and their mixes are responsible for 74% of attacks that were included in the study, 68% of the attacks upon children, 82% of the attacks upon adults, 65% of the deaths, and 68% of the maimings. In more than two-thirds of the cases included in the study, the life-threatening or fatal attack was apparently the first known dangerous behavior by the animal in question. Clifton states:
Clifton's opinions are as interesting as his statistics. For example, he says, "Pit bulls and Rottweilers are accordingly dogs who not only must be handled with special precautions, but also must be regulated with special requirements appropriate to the risk they may pose to the public and other animals, if they are to be kept at all."
Clifton's website is Animals 24/7 and his compendium of pit bull information is titled Pit Bull Statistics. He is one of the top two researchers in the USA pertaining to pit bulls, the other being Colleen Lynn whose website is Dogs Bite. Ms. Lynn's entire website is devoted to detailed analysis of pit bull mayhem.
The areas of the body that are bitten
Judging only by hospital admissions, 43 percent of people hospitalized for dog bites required treatment for skin and underlying tissue infection; 22 percent had wounds of the legs or arms; 10.5 percent had wounds of the head, neck and torso; and the remaining patients had problems ranging from bone fracture to blood poisoning. (US Dept. of Health and Human Services, Agency for Healthcare Research and Quality.)
The financial impact of dog bites
Dog attack victims in the US suffer over $1 billion in monetary losses every year. ("Take the bite out of man's best friend." State Farm Times, 1998;3(5):2.) That $1 billion estimate might be low -- an article in the Journal of the American Medical Association reported that, in 1995, State Farm paid $70 million on 11,000 claims and estimated that the total annual insurance cost for dog bites was about $2 billion. (Voelker R. "Dog bites recognized as public health problem." JAMA 1997;277:278,280.)
Researchers from the CDC estimated that the direct medical costs of dog bites per year equaled $164.9 million in the USA toward the end of the 1990s. Quinlan KP, Sacks JJ. Hospitalizations for Dog Bite Injuries [letter] JAMA 1999; 281:232-233.
Dog bites accounted for more than one-third of all homeowners insurance liability claim dollars paid out in 2012, costing more than $489 million, according to the Insurance Information Institute (I.I.I.) and State Farm, the largest writer of homeowners insurance in the United States. The average cost paid out for dog bite claims was $29,752 in 2012. From 2003 to 2012 the cost of the average dog bite claim increased by 55.3 percent. (Average Number of Dog Bite Claims Falls in 2012; Claims Costs Still on the Rise, Increasing by More Than 50 Percent Since 2003, Insurance Information Institute, May 2013.)
In 2010, State Farm Insurance Company paid 3,500 dog bite claims throughout the USA made uder homeowners insurance policies. The average payout was $25,714, for a total of $90 million. During the same period, the company paid 369 dog bite claims in California under homeowners policies. The average in California was $29,810 per claim -- 16% higher than the national average. The company paid a total of $11 million for such claims during that period. (State Farm press release, May 10, 2011.)
The scene of the attack
Over 50 percent of the bites occur on the dog owner's property. (See Insurance Information Institute, Dog Bite Liability, accessed 8/30/07.)
Dogs bite family and friends
The vast majority of biting dogs (77%) belong to the victim's family or a friend.
The USA is not the only country with the dog bite problem. In Britain, the number of people being admitted to accident and emergency (A&E, called the "emergency room" or "ER" in the USA) as a result of dog attacks has risen by 43 per cent in the last four years. Hospitalisation of children and young people has risen by a fifth, while 58 per cent more adults are being admitted to A&E due to attacks by dogs. In London there has been a 119 per cent rise in hospitalisation of under-18s as a result of dog attacks. (Read the articles in the Evening Standard and on inthenews.co.uk.)
Canadian statistics are contained in Injuries Associated With Dog Bites and Dog Attacks, from CHIRPP (Canada). Australian statistics are summarized in The public health impact of dog attacks in a major Australian city, from The Medical Journal of Australia.

See the links to Karen Delise and Colleen Lynn, above. They and Merrit Clifton have ongoing studies of the dog bite problem and have different points of view as to its cause, significance and effect.
Dog bite losses exceed $1 billion per year. In 2015, 35 Americans were killed by dogs, down from 42 the prior year. Each year, more than 350,000 dog bite victims are seen in emergency rooms, and approximately 850,000 victims receive medical attention. Data that the CDC collected in the USA between 2001 and 2003 indicated there were 4.5 million dog bite victims per year, but that figure appears to be rising.
Despite the number of victims, only 15,000 to 16,000 of them per year receive money from homeowners insurance companies and renters insurance companies. This means that out of the 850,000 who get medical attention, only two victims per 100 receive compensation. Although insurers pay over $350 million to victims, the nationwide, average insurance payment for a dog bite case is only $29,752. The payouts have increased by 55.3 percent in the past decade.
