Dog Bite Statistics: What the Numbers Really Show

What are the statistics on dog bites?

Bite statistics refer to the systematic recording of dog bite incidents: frequency, severity, victim profile, dog breeds involved, and contextual factors. They form the data basis for legal regulations (breed bans, leash laws) and prevention campaigns.

The problem: Bite statistics are incomplete in most countries. Only a fraction of bites receive medical treatment, and an even smaller proportion are reported to the police. The available figures significantly underestimate the actual incidence.

Background + Scientific Context

Sarenbo and Svensson (2021, *Forensic Science International*, PubMed 33246867) analyzed European deaths caused by dogs (ICD-10 code W54) based on Eurostat data from 1995–2016: In 2016, 45 Europeans died from dog-related causes (incidence 0.009/100,000). The death rate increased over the observation period, with significant national variations. Those most frequently affected were children and older adults. While mortality is rare, it represents a real threat to vulnerable groups.

In a UK community-based study (n=694), Westgarth et al. (2018, J Epidemiol Community Health, PubMed 29437877) found that 24.8% of respondents had been bitten at least once in their lifetime, with an incidence of 18.7 per 1,000 per year. Only one-third of the bites required medical attention. Men and owners of multiple dogs were bitten more frequently. Most bites were caused by familiar dogs—not by unfamiliar stray dogs.

Cornelissen and Hopster (2010, Veterinary Journal, PubMed 19879172) analyzed Dutch data on bite victims (n=1,078): Breed-specific risk indices showed no consistent pattern that would justify breed-specific legislation. The authors recommend context-based prevention rather than breed bans.

Vitomalia-Position

Breed bans are not evidence-based. The scientific evidence—including Cornelissen and Hopster (2010) and several comparative European studies—provides no convincing proof that breed bans reduce the number of dog bites. Dog breed accounts for only a small portion of the risk of biting; socialization, ownership practices, training, and context account for far more. We support the position of the AVSAB and the German Veterinary Association: regulation should target behavior and the context of ownership, not breed characteristics.

Anatomy is not a trait. This also applies to breeds on national lists.

When do dog bite statistics become relevant?

• As a basis for discussions about dogs on the list and breed bans
• When interpreting media reports about "dangerous dogs"
• For dog owners whose dogs are subject to dog ownership regulations
• When assessing whether a particular dog poses a statistically higher risk
• As an argument in political debates regarding leash laws and pet ownership regulations

Practical application

What the statistics consistently show:

What statistics CAN'T show:

Total number of bites (significantly underreported), data on causes and context (lack of documentation), and the preventive effect of breed bans (difficult to isolate and verify).

Risk factors supported by robust evidence: - Unneutered male dog (increased risk of aggression) - Lack of socialization - Fear as a trigger (pain, threat, confinement) - Children left unsupervised with unfamiliar dogs

Common Mistakes & Myths

• “Certain breeds bite more often.” Breed statistics are methodologically problematic: population sizes are unknown, breed identification is unreliable, and reporting patterns are skewed. No study has shown that individual breeds are biologically more aggressive—context and handling are the dominant factors.
• “Breed bans make cities safer.” The evidence is scant. UK data from the Dangerous Dogs Act shows no clear decline in the number of dog bites following the ban on certain breeds.
• “Bites always happen because of strange dogs.” The opposite is actually more common: Westgarth et al. (2018) show that most bites are inflicted by dogs known to the victim within the family or social circle.

Current State of Research (2026)

Europe-wide harmonization of bite documentation remains a priority for further research. Current recommendations (WHO, European Veterinary Chambers) prioritize context-based prevention—educating parents and children, ensuring safe human-dog interactions, and implementing behavior-based ownership requirements—over breed-specific regulations.

Frequently Asked Questions

Which dogs bite the most?

There is no reliable breed-specific data—breed classification in bite statistics is unsystematic, and population sizes are unknown. What is consistently documented is that children are the most common victims, intact male dogs are more frequently involved, and the most common context is when the dog is known and in a familiar environment.

Do breed bans reduce the number of dog bites?

The evidence does not support this. Studies from the UK, the Netherlands, and other countries with breed-specific bans show no consistent decline in the number of dog bites. Context-based prevention—education, socialization, and ownership requirements—is considered more effective.

What is the risk of being bitten by a dog?

Westgarth et al. (2018) report a lifetime prevalence of ~25% for the UK—meaning that about one in four people will be bitten at some point in their lives. Most bites are minor and do not require medical attention. Serious injuries and fatalities are rare, but disproportionately affect children.
