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,{{r|Hoffman|Oxford|Webster}} while the Staffordshire Bull Terrier is not considered a pit bull.{{r|Hoffman|Olson|Allen}} 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.{{r|Fogle|Morris|Beaufoy}}

Proponents of the type and advocates of regulation have engaged in a highly contentious nature-versus-nurture debate over whether aggressive tendencies in pit bulls may be appropriately attributed to owners' poor care for and competency to handle the dog or inherent qualities owing to their breeding for fighting purposes.{{Cite web|last=Glazebrook|first=Louise|date=2016-04-13|title=What makes an animal dangerous?

History
File:Benjamin Marshall - Dustman - Bulldog and Terrier Mix.jpg
The term has been used since at least the early 20th century.{{cite web |title=The Dog fancier v.12 1903 |url=https://babel.hathitrust.org/cgi/pt?id=hvd.32044095334702&view=1up&seq=258&q1=%22pit%20bull%22 |publisher=The Dog fancier |page=28 |date=1903}}{{r|Webster}} It is believed all dogs that are now classified as pit bulls descend from the British bull-and-terrier, which were first imported into North America in the 1870s.{{r|Fogle|Morris}} The bull-and-terrier was a breed of dog developed in the United Kingdom in the early 19th century for the blood sports of dog fighting and rat baiting. It was created by crossing the ferocious, thickly muscled Old English Bulldog with the agile, lithe, feisty Black and Tan Terrier.{{r|Fogle|Morris}} The aggressive Old English Bulldog, which was bred for bear and bull baiting, was often also pitted against its own kind in organized dog fights, but it was found that lighter, faster dogs were better suited to dogfighting than the heavier Bulldog.{{r|Fogle|Morris|Beaufoy}} To produce a lighter, faster, more agile dog that retained the courage and tenacity of the Bulldog, outcrosses from local terriers were tried, and ultimately found to be successful.{{r|Fogle|Morris|Beaufoy}}
As it was in the UK, dog fighting became a popular pastime in 19th century America and bull-and-terriers were imported to the New World to pursue the blood sport.{{r|Fogle|Morris}} In the United States, organized dog fights have been progressively outlawed in various states since 1874, culminating in federal legislation criminalizing animal fighting in 2007.{{r|Kalouf}}
In the 1890s breeders of American pit bull–type dogs attempted to have their dogs recognized by the American Kennel Club, but because of the type's association with dogfighting, the club rejected these entreaties.{{r|Fogle|Morris}} Following this rejection, in 1898 breeders of American Pit Bull Terriers established a rival kennel club, the United Kennel Club. In addition to being a breed registry, the United Kennel Club also regulated dogfights.{{r|Fogle|Morris|Wilcox}} In the 1930s the American Kennel Club was faced with a dilemma: whilst not wishing to condone dogfighting, there was a desire to recognize a uniquely American dog breed for which over 30 years of breed records existed.{{r|Fogle|Morris|Wilcox}} The solution was to recognize Pit Bull Terriers under a different name and prohibit these dogs from being used in organized fights, and in 1935 the American Kennel Club recognized Pit Bull Terriers as Staffordshire Terriers.{{r|Fogle|Morris|Wilcox}}File:003 American Pit Bull Terrier.jpg
The name "Staffordshire Bull Terrier" was first used in Britain in 1930 in advertisements for bull-and-terrier-type dogs.{{r|Beaufoy}} Organized dog fighting had been effectively eliminated in the United Kingdom by the Protection of Animals Act 1911, but devotees of the bull-and-terrier type continued to breed these dogs, predominantly in England's Black Country.{{r|Beaufoy}} Throughout the early 1930s attempts were made in England to gain recognition for these dogs with The Kennel Club; these efforts were successful in 1935.{{r|Fogle|Morris|Kalouf}} In order to avoid confusion with the British breed, in 1972 the American Kennel Club changed the name of their American breed to the American Staffordshire Terrier.{{r|Morris|Wilcox}}
Despite criminalisation, illegal fights using pit bull–type dogs have continued to be widespread in the United States. In the 1990s in that country it was estimated 1,500 dogs died annually in organized fights, and by the mid-2000s it was estimated over 40,000 people were involved in the illegal blood sport.{{r|Fogle|Morris|Kalouf}} Pit bull–type dogs are also used by criminal organizations to guard illegal narcotics, and to intimidate and attack civilians, other criminals and police, the type becoming a status symbol in American gang culture.{{r|Kalouf}}{{cite news|last=Cook|first=Frank|title=Pit bulls becoming drug dealers weapon of preference|url=https://www.upi.com/Archives/1987/06/29/Pit-bulls-becoming-drug-dealers-weapon-of-preference/6208551937600|date=June 29, 1987|publisher=United Press International|access-date=December 21, 2019|archive-date=December 21, 2019|archive-url=https://web.archive.org/web/20191221182621/https://www.upi.com/Archives/1987/06/29/Pit-bulls-becoming-drug-dealers-weapon-of-preference/6208551937600/|url-status=live}}{{cite news |first1=Al |last1=Baker |first2=Mathew R. |last2=Warren |title=Shooting highlights the risks dogs pose to police, and vice versa |date=July 9, 2009 |place=New York, NY |newspaper=The New York Times |url=https://www.nytimes.com/2009/07/10/nyregion/10pitbull.html |access-date=January 7, 2010 |archive-date=November 16, 2012 |archive-url=https://web.archive.org/web/20121116022218/http://www.nytimes.com/2009/07/10/nyregion/10pitbull.html |url-status=live }} On the other side of the law, pit bull–type dogs have been used by U.S. Customs and Border Protection as drug detection dogs.{{cite journal |date=October 2002 |title=Cool K-9 Popsicle retires |journal=U.S. Customs Today |volume=38 |issue=#10 |url=http://www.cbp.gov/xp/CustomsToday/2002/October/k9.xml |access-date=August 7, 2009 |archive-url=https://web.archive.org/web/20111024001344/http://www.cbp.gov/xp/CustomsToday/2002/October/k9.xml |archive-date=October 24, 2011}}{{cite news |first=Adrienne Mand |last=Lewin |title=Protecting the Nation — One Sniff at a Time |date=October 12, 2005 |publisher=ABC News |url=https://abcnews.go.com/Technology/Terrorism/story?id=1200304&page=1 |access-date=February 2, 2009 |archive-date=March 22, 2007 |archive-url=https://web.archive.org/web/20070322183804/http://abcnews.go.com/Technology/Terrorism/story?id=1200304&page=1 |url-status=live }}

The burden of proof can lie with the dog owner or with the authorities. In Denmark, the police can request that a dog owner provides proof that the dog is not prohibited under the Danish Dog Act. Danish authorities recommend that dog owners make sure they have documentation of their dog's origin and breed, especially if their dog has characteristics similar to those prohibited: "Possessors of a dog, which in appearance have some features in common with one or more of the prohibited breeds, are recommended to ensure that they possess documentation of their dog's breed."{{Cite web |title=Danish Legislation on Dogs |url=https://en.foedevarestyrelsen.dk/animals/animal-welfare/danish-legislation-on-dogs |access-date=2025-02-11 |website=en.foedevarestyrelsen.dk |language=en}}{{Citation |last=Ministeriet for Fødevarer, Landbrug og Fiskeri |title=Bekendtgørelse af lov om hunde |date=2021-02-03 |url=https://www.retsinformation.dk/eli/lta/2021/329 |access-date=2025-02-11}}
In the United Kingdom it is also a dog owner's responsibility to prove that the dog is not one of the prohibited types (dog types bred for fighting) under the Dangerous Dogs Act 1991 or that the dog has a Certificate of Exemption (grandfather clause). The UK uses Dog Legislation Officers (DLO) which have special training and experience in dog identification. Those officers also provide expert evidence for authorities.{{Cite web |title=Controlling your dog in public |url=https://www.gov.uk/control-dog-public/banned-dogs |access-date=2025-02-11 |website=GOV.UK |language=en}}{{Cite web |title=Dangerous Dog Offences |website=The Crown Prosecution Service |url=https://www.cps.gov.uk/legal-guidance/dangerous-dog-offences |access-date=2025-02-11}}
Methods
There are various ways to identify a pit bull's specific breed. It can be proven through registration papers (pedigree){{Cite web |title=Importance of Pedigree Papers |url=https://dogsaustralia.org.au/getting-a-dog/importance-of-pedigree-papers/ |access-date=2024-12-12 |website=dogsaustralia.org.au}} and through testing a dog's DNA to validate parentage or it can be determined through testing DNA-based ancestry,{{Cite web |last=Wiley |first=Claire |date=2023 |title=Genetic Testing in Dogs – an Overview |url=https://www.akc.org/expert-advice/dog-breeding/genetic-testing-dogs-overview/ |access-date=2024-12-12 |website=American Kennel Club |language=en}} through examining a dog's traits{{Cite journal |last1=Kriangwanich |first1=Wannapimol |last2=Nganvongpanit |first2=Korakot |last3=Buddhachat |first3=Kittisak |last4=Siengdee |first4=Puntita |last5=Chomdej |first5=Siriwadee |last6=Ponsuksili |first6=Siriluck |last7=Thitaram |first7=Chatchote |date=2020 |title=Genetic variations and dog breed identification using inter-simple sequence repeat markers coupled with high resolution melting analysis |journal=PeerJ |volume=8 |pages=e10215 |doi= 10.7717/peerj.10215|doi-access=free |issn=2167-8359 |pmc=7605226 |pmid=33194413}} or the use of artificial intelligence.{{Cite journal |title=Hybrid Deep Learning Algorithms for Dog Breed Identification—A Comparative Analysis |url=https://ieeexplore.ieee.org/document/10192536 |archive-url=http://web.archive.org/web/20240420045846/https://ieeexplore.ieee.org/document/10192536/ |archive-date=2024-04-20 |access-date=2024-12-12 |journal=IEEE Access |date=2023 |doi=10.1109/ACCESS.2023.3297440 |language=en-US |last1=Valarmathi |first1=B. |last2=Gupta |first2=N.

While some methods might be good enough to satisfy a dog owner's curiosity, not all methods are accepted for legal reasons. For example, France banned pit bull type dogs (category 1) in 1999, but purebred registered American Staffordshire Terriers (category 2) are only restricted, not banned. Therefore only American Staffordshire Terriers registered with Central Canine Society (fr. Société centrale canine) are legally allowed to be in or to re-enter the country. Parental DNA testing of a not-registered purebred dog would not be sufficient under French law to legally transfer such a dog into or through France.{{Cite web |title=Avoir un chien de catégorie: quelles sont les règles ? |trans-title=Having a category dog: what are the rules? |url=https://www.service-public.fr/particuliers/vosdroits/F1839 |access-date=2025-02-11 |website=www.service-public.fr |language=Fr}}

Dog type identification
Breed assessors look at a suspected pit bull's physical characteristics like the shape of the head, ears, flews, jowls, teeth, eyes, chest, legs and tail, as well as the characteristics of the dog's coat (color, hair length, growth and texture), skin, weight, height and body length to determine if a dog categorizes as a pit bull type dog or not.{{Cite web |last=Council |first=Manawatū District |date=2024-04-23 |title=Dog Classification |url=https://www.mdc.govt.nz/services/animal-control/dogs/dog-classification |access-date=2025-02-12 |website=www.mdc.govt.nz |language=en}}[https://www.olg.nsw.gov.au/wp-content/uploads/2020/03/Guidelines-For-Breed-Assessors-may-2013.pdf Companion Animals Act 1998, Guidelines for breed assessors].

"Pit bull-type dogs are defined as any dog displaying a majority of physical traits of any one or more of the specific breeds mentioned above [American Pit Bull Terrier, American Staffordshire Terrier, or Staffordshire Bull Terrier], or any dog exhibiting those distinguishing (physical) characteristics that substantially conform to the standards established by American Kennel Club or United Kennel Club".[https://denver.prelive.opencities.com/files/assets/public/v/1/animal-shelter/documents/restrictedbreed_faq_1.8.21.pdf Denver Pit Bull Fact Sheet].

Whether the dog type pit bull can be sufficiently defined has been the subject of legal disputes. For example, the claim that the legal phrase "commonly known as a pit bull dog" is unconstitutionally vague has been dismissed by judicial decisions: "...the ownership of a dog 'commonly known as a pit bull dog' is prima facie evidence of the ownership of a vicious dog, is not unconstitutionally void for vagueness since dogs commonly known as pit bulls possess unique and readily identifiable physical and behavioral traits which are capable of recognition both by dog owners of ordinary intelligence and by enforcement personnel." The court also found that specific behavioral features distinguish pit bulls from other dogs and therefore can be taken into account when identifying a pit bull: "Furthermore, the dog owner of ordinary intelligence, when determining whether he or she owns a pit bull dog, need not rely solely on the dog's physical traits. Rather, the pit bull possesses certain distinctive behavioral features which differentiate it from other dog breeds."[https://casetext.com/case/state-v-anderson-227 State v.

Challenges of mixed or cross breed identification
Mixed or cross breed identification can be more challenging than pure breed identification and can be supported by testing for genetic markers. However, DNA-based ancestry testing that works with owner-reported databases can be unreliable and the American Kennel Club does not recommend using those. For example, the Manawatū District Council does not accept DNA heritage testing for pit bulls, instead they look at a dog's certain physical traits.{{Cite web |last= |first= |date=2024-04-23 |title=Dog Classification |url=https://www.mdc.govt.nz/services/animal-control/dogs/dog-classification |access-date=2025-01-19 |website=www.mdc.govt.nz |publisher=Manawatū District Council |language=en |quote="The Manawatū District Council will use the guidance set out in this section to identify the American Pit Bull type.

For a range of reasons, this testing is not always conclusive, especially where a dog is a mix of breeds."}}

Deliberate mislabeling of pit bulls
In Australia some dog owners give false information regarding the breed of their dog to local authorities, despite this being an offence under the Crimes Act. Inquests after fatal or serious dog attacks showed that pit bull owners registered their dogs under a wide range of other breeds, like the Australian Terrier, to evade their local laws and regulations.{{Cite news |last=Fife-Yeomans |first=Janet |date=2014-04-26 |title=Lethal dogs in disguise: pitbulls registered under other breeds |url=https://www.couriermail.com.au/news/lethal-dogs-in-disguise-pitbulls-registered-under-other-breeds/news-story/99e777e8a5547e33beecad813c0a3c23 |access-date=2024-12-12 |work=The Courier Mail}}{{Cite web |last=Deare |first=Steven |date=2024-02-19 |title=Dog breeder claims may put unsuspecting owners at risk |url=https://www.canberratimes.com.au/story/8526406/dog-breeder-claims-may-put-unsuspecting-owners-at-risk/ |access-date=2024-12-12 |website=www.canberratimes.com.au |language=en-au}}

Dog attack and death risk
{{See also|Dog bite|List of fatal dog attacks}}A 2000 joint review project between researchers in the Centers for Disease Control and Prevention (CDC), Humane Society of the United States (HSUS) and American Veterinary Medical Association (AVMA) found the data indicated that Rottweilers and pit bull–type dogs accounted for 67% of human dog bite-related fatalities in the United States between 1997 and 1998, and followed with "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." Pit bull–type dogs were identified in approximately one-third of dog bite-related fatalities in the United States between 1981 and 1992. The review notes that studies on dog bite-related fatalities which collect information by surveying news reports are subject to potential errors, as some fatal attacks may not have been reported, a study might not find all relevant news reports, and the dog breed might be misidentified.{{cite web |last1=Sacks |first1=Jeffrey J. |last2=Sinclair |first2=Leslie |last3=Gilchrist |first3=Julie |title=Breeds of dogs involved in fatal human attacks in the United States between 1979 and 1998 |url=https://www.cdc.gov/homeandrecreationalsafety/images/dogbreeds-a.pdf |publisher=Centers for Disease Control and Prevention |archive-url=https://web.archive.org/web/20151116130816/http://www.cdc.gov/homeandrecreationalsafety/images/dogbreeds-a.pdf |archive-date=November 16, 2015 |date=September 15, 2000 }} However, after 2000 the CDC stopped tracking dog bites, and in 2001, Julie Gilchrist, a CDC pediatrician and epidemiologist, stated that part of the reason the CDC stopped collecting dog bite data was because "making meaningful analysis [of the data][was] nearly impossible".{{Cite web|url=https://www.avma.org/javma-news/2017-11-15/dangerous-dog-debate|title=The dangerous dog debate | American Veterinary Medical Association|date=November 2017 }}
In a 2021 review of 19 retrospective dog bite studies from U.S. Level I trauma centers, pit bulls were found to inflict a higher prevalence and severity of injuries compared with other breeds.{{Cite journal|pmid = 34100808|year = 2021|last1 = Reuter Muñoz|first1 = K.

The study found that the proportion of bites caused by German Shepherds decreased by 0.63 percent per year over that time interval while the proportion caused by pit bulls increased by 1.17 percent per year. The pit bull proportion of dog bites increased more slowly in Denver, Colorado, where breed-specific legislation had been in place.
In a 2014 literature review of dog bite studies, the American Veterinary Medical Association (AVMA) argues that breed is a poor sole predictor of dog bites. According to the AVMA, controlled studies have not identified pit bulls as disproportionately dangerous, but other studies have found that, compared with other dog breeds, pit bulls were more likely to inflict complex injuries, are more likely to attack unprovoked, and are more likely to go off property to do so.{{Cite journal|pmid = 31816277|year = 2020|last1 = Khan|first1 = K.|last2 = Horswell|first2 = B.

Pit bulls were originally developed from dogs that were bred for bull baiting and dog fighting. Pit bull attacks are often perceived as taking place "without warning", possibly due to the type's fighting heritage, as fighting dogs that do not signal aggression may do better in the ring.{{cite journal |last1=Bini |first1=John K. |last2=Cohn |first2=Stephen M. |title=Mortality, Mauling, and Maiming by Vicious Dogs |journal=Annals of Surgery |date=April 2011 |volume=253 |issue=4 |pages=791–797 |doi=10.1097/SLA.0b013e318211cd68 |pmid=21475022|url=https://assets.gov.ie/224373/f881b086-0803-4e92-8773-e45ef1e4db94.pdf}} However, recent research suggests that this perception may reflect a lack of knowledge of dog body-language, and owners' over-confidence in their ability to interpret those signs.{{cite web | url=https://phys.org/news/2023-06-reveals-links-dog-behavior.html | title=New research reveals links between dog attacks and misunderstanding of dog behavior }} In fighting with dogs of other breeds, pit bulls, German Shepherds, Great Danes and Rottweilers were often the aggressor, and more than twenty percent of studied Akitas, Jack Russell Terriers and pit bulls displayed serious aggression towards other dogs.{{cite journal |last1=Duffy |first1=D.L. |last2=Hsu |first2=Yuying |last3=Serpell |first3=James A. |title=Breed differences in canine aggression |journal=Applied Animal Behaviour Science |date=18 April 2008 |volume=114 |issue=3–4 |pages=441–460 |doi=10.1016/j.applanim.2008.04.006 |url=https://www.sciencedirect.com/science/article/abs/pii/S0168159108001147 |access-date=13 September 2020}} Although there may be a connection between breed of dog and aggression towards humans, the difficulty of classifying dog attacks by specific breed after the fact has made this point controversial and debated.{{cite journal |last1=Gunter |first1=Lisa M. |last2=Barber |first2=Rebecca T. |last3=Wynne |first3=Clive D.L. |title=What's in a Name?

Pit bulls also have higher rates of unsuccessful adoptions, and are more likely than other kinds of dogs to be returned to a shelter multiple times and eventually euthanized. Whether pit bull adoptions fail more often than other types of dog due to breed behavioral traits, or due to public stigma, is not known, but in general the most common reasons why shelter dog adoptions fail are behavioral problems or incompatibility with the adopter's existing pets.

Many of the jurisdictions that restrict pit bulls apply their restriction to the modern American Pit Bull Terrier, American Staffordshire Terrier, Staffordshire Bull Terrier, and any other dog that has the substantial physical characteristics and appearance of those breeds, such as the Canadian province of Ontario.{{cite web |date=August 29, 2005 |title=An Act to amend the Dog Owners' Liability Act to increase public safety in relation to dogs, including pit bulls, and to make related amendments to the Animals for Research Act |url=http://www.e-laws.gov.on.ca/html/statutes/english/elaws_statutes_90d16_e.htm |url-status=live |archive-url=https://web.archive.org/web/20100702074542/http://www.e-laws.gov.on.ca/html/statutes/english/elaws_statutes_90d16_e.htm |archive-date=July 2, 2010 |access-date=July 5, 2010 |publisher=Government of Ontario, Canada}} A few jurisdictions, such as Singapore, also classify the modern American Bulldog as a "pit bull–type dog".{{cite web |date=November 15, 2010 |title=List of Scheduled Dogs |url=https://www.ava.gov.sg/docs/default-source/tools-and-resources/resources-for-businesses/summaryofab_doglicensingcontrol_rules_15nov2010 |archive-url=https://web.archive.org/web/20150827031216/http://www.ava.gov.sg/docs/default-source/tools-and-resources/resources-for-businesses/summaryofab_doglicensingcontrol_rules_15nov2010 |archive-date=August 27, 2015 |access-date=February 20, 2018 |publisher=Agri-Food and Veterinary Authority of Singapore}}
Breed-specific legislation has been largely found to be ineffective at reducing the number of dog attacks.{{cite web |title=Position Statement on Breed-Specific Legislation |url=https://avsab.org/wp-content/uploads/2018/03/Breed-Specific_Legislation-download-_8-18-14.pdf |url-status=live |archive-url=https://web.archive.org/web/20200527062101/https://avsab.org/wp-content/uploads/2018/03/Breed-Specific_Legislation-download-_8-18-14.pdf |archive-date=May 27, 2020 |access-date=August 15, 2020 |publisher=The American Veterinary Society of Animal Behavior}} Debates often center on whether apparent aggressive tendencies are the result of poor dog ownership or natural behaviors of the breed.
Some municipalities take the opposite approach, and have passed anti-BSL laws. Anti-BSL laws have been passed in 21 of the 50 states in the United States, prohibiting or restricting the ability of jurisdictions within those states to enact or enforce breed-specific legislation.{{cite web |title=Overview of States that Prohibit BSL - Animal Legal & Historical Center |url=https://www.animallaw.info/article/overview-states-prohibit-bsl |website=www.animallaw.info}}
Some municipalities started with BSL laws, then repealed them, such as Denver, Colorado.{{Cite web |last=Swanson |first=Conrad |date=2020-11-04 |title=Denver election results for 2J: Voters repeal city's pit bull ban |url=https://www.denverpost.com/2020/11/03/denver-election-results-2j-pit-bull/ |access-date=2023-03-17 |website=The Denver Post |language=en-US}}

= Liability insurance =
Dog owners in the United States can be held legally liable for injuries inflicted or caused by their dogs. In general, owners are considered liable if they were unreasonably careless in handling or restraining the dog, or if they knew beforehand that the dog had a tendency to cause injury (e.g., bite); however, dog owners are automatically considered liable if local laws hold an owner strictly liable for all damage caused by their dog, regardless of carelessness or foreknowledge of a dog's tendencies. Homeowners and renters insurance policies typically provide liability coverage from US$100,000–300,000 for injuries inflicted by dogs;{{cite web |title=Dog Bite Liability |publisher=Insurance Information Institute |date=September 2009 |url=http://www.iii.org/media/hottopics/insurance/dogbite/ |access-date=September 24, 2009 |archive-date=June 15, 2009 |archive-url=https://web.archive.org/web/20090615052434/http://www.iii.org/media/hottopics/insurance/dogbite/ |url-status=live }} however, some insurance companies limit their exposure to dog bite liability claims by putting restrictions on dog owners that they insure. These restrictions include refusing to cover dog bites under the insurance policy, increasing insurance rates for homeowners with specific breeds, requiring owners of specific breeds to take special training or have their dogs pass the American Kennel Club Canine Good Citizen test,{{cite web |title=Homeowners Insurance Available to Breeds Previously Excluded with CGC Certification |publisher=American Kennel Club |date=October 1, 2004 |url=http://www.akc.org/news/index.cfm?article_id=2408 |access-date=February 4, 2009 |archive-date=September 14, 2010 |archive-url=https://web.archive.org/web/20100914051327/http://www.akc.org/news/index.cfm?article_id=2408 |url-status=live }} requiring owners to restrict their dogs with muzzles, chains, or enclosures, and refusing to write policies for homeowners or renters who have specific breeds of dogs.
Owners of rental properties may also be held liable if they knew an aggressive dog was living on their property and they did nothing to ensure the safety of other tenants at the property; as a result, many rental properties forbid pit bull–type dogs and any other breeds if the rental property's insurance will not cover damage inflicted by that type of dog.{{cn|date=April 2024}} The dog breeds most often not covered by insurance companies include pit bull–type dogs, Rottweilers, German Shepherd Dogs, Doberman Pinschers, Akitas (Akita Inu and American Akitas), and Chow Chows.{{cite web |first=Brian |last=Sodergren |title=Insurance companies unfairly target specific dog breeds |publisher=Humane Society of the United States |url=http://www.hsus.org/pets/issues_affecting_our_pets/insurance_companies_unfairly_target_specific_dog_breeds.html |access-date=August 12, 2009 |archive-url=https://web.archive.org/web/20090707221314/http://www.hsus.org/pets/issues_affecting_our_pets/insurance_companies_unfairly_target_specific_dog_breeds.html |archive-date=July 7, 2009}}{{better source needed|date=October 2021}}
In 2013, Farmers Insurance notified policyholders in California that it would no longer cover bites by pit bulls, Rottweilers and wolf-dog hybrids. A spokeswoman for Farmers said that those groups account for more than a quarter of the agency's dog bite claims.
