Dog bite statistics

A large amount of data about dog bite statistics and injury inflicted by dogs to people has been researched and published in the last several decades. We now know more about who gets bit, where they get bit and who they are bitten by. So for example, children are bitten more often than adults, the majority of victims are bitten by a dog they know and most of the incidences happen on the dog’s home turf. What is more controversial is what breeds are involved and to what extent. This topic remains controversial. Recent peer-reviewed research has provided answers to this question, however.

The epidemiological and statistical analyses of dog bites cover a broad range of topics such as:

  • The breed, gender, and age of the dog which inflicted the bite;
  • The circumstances and context in which the bite occurred;
  • The gender, age of the dog bite victim;
  • Costs associated with treating dog bite injuries;
  • Types of injuries associated with dog bites, including psychological trauma such as  post-traumatic stress disorder;
  • Fatal dog attacks;
  • Statistical analyses of breed specific legislation;
  • Statistical analysis of the effects of  programs for dog bite safety 

Collecting dog bite statistics is an important area of public health inquiry: the frequency of dog bites is high, costs are staggering and the emotional and physical damage inflicted onto a human, particularly a child, from an attack by a dog can be great. A better understanding of the epidemiology of dog bites thru understanding of statistical patterns is, therefore, necessary for programs and education about dog bite prevention.

Important considerations about dog bites statistics

 #1. The frequency of dog bites in the USA is no longer at epidemic proportions

In recent years there has been a substantial decrease in frequency in nonfatal dog bites to children. Currently, it appears that the overall frequency of nonfatal dog bites has decreased or at least stabilized. Consequently, it would be misleading to characterize dog bites in the USA as an “epidemic”, as it was done 30 years ago.  No doubt that dog bite problem continues, as evidenced in the 4.5 million people are bitten by dogs in the United States. nonetheless, the dog bite problem in the USA appears to have lessened, probably the result of educational efforts -and not through legislation which restricts or prohibits ownership of certain so-called “dangerous” breeds.

Attacks on people by dogs will always happen because dogs are ingrained into culture and society.  Moreover, attacks happen because of the recklessness and careless handling of certain dog owners. The bottom line: this public health problem will never go away: the best that could be done is to control it. Fortunately, unlike India, in the USA and in other Western countries, rabies is not a serious concern.

 #2. Bite statistics should always be considered in the context in which an incident happens

Statistical information on dog bites should not be presented out of context. As much specificity should be given, if available, about the particular statistic. For example, since relatively detailed information and statistics about dog bites to children are available, it would be misleading (but not necessarily inaccurate), to represent in a general sense that children are the ones most frequently bitten by dogs (as some attorneys might do to argue foreseeability in a personal injury case). Specificity should be provided because it is also known that boys are more frequently bitten than girls, children under 10 years of age are bitten more frequently than children over 10 years, children under 6 years are the population most severely bitten, and children sustain dog bites most frequently during the springtime and summer months.

#3. No conclusive evidence indicates that BLS lowers the frequency of dog bites in the general population

Studies have been undertaken about dog bite frequency and in Ireland, England, Spain, and  Belgium.  Results from these studies show no correlation between the frequency of dog bites in the general population and the restriction of certain so-called “dangerous” breeds.
