More evidence against breed specific legislation

UK legislation that targets ‘dangerous dogs’ has not been shown to reduce dog bites and policies should be based on evidence and risk assessment, suggests a new article.

Rachel Orritt, a PhD student of psychology at the University of Lincoln says that dog bites present a “public health risk of unknown magnitude but no scientific evidence upon which to base a reliable UK estimate has been obtained in the past two decades.”

She also says that discussion by medical professionals about the impact of dog-human interactions “sometimes ignores the health benefits concomitant with dog ownership” with one writer in The British Medical Journal suggesting that “the only way to stop dog bites will be to ban dogs.”

Orritt says there are several studies that show owning a dog is associated with increased physical activity, better self esteem and fewer annual visits to the doctor. She adds that “eradicating dogs would have negative consequences for human health.”

She argues that the British news media “confound the matter further through inaccurate representation of the risk posed by dogs.”

Inaccurate reporting of dog bites, coupled with public pressure “have contributed to the drafting of legislation,” she writes. The Dangerous Dog Act 1991 has been amended in an effort to improve this legislation “but has been shown to be ineffective at reducing dog bite incidence.”

Orritt says that to reduce dog bite incidence, “academics and medical and veterinary practitioners need to cooperate to develop effective, scientifically sound risk management strategies. These should be evidence based and should not depend on politically driven initiatives such as the current legislation.”

Risk assessment for human violence has proved to be accurate and reliable and Orritt says this “might be a practical preventative measure to reduce injury from dog bite” along with medical and veterinary professionals “familiarising themselves with evidence based resources.”

She says that attention must also be given to the psychological health of patients after trauma.

Orritt believes that research is needed to improve care and an “estimate of dog bite incidence” but until this is done, “the scale of the problem is entirely unknown.”

She concludes that evidence based measures to inform ongoing risk management, such as developing effective risk assessments, “should result in the reduction in dog bite injuries that punitive legislation has not achieved.”

Visual identification of breed – one reason why BSL doesn’t work

I’m ‘on the record’ that I don’t support breed specific legislation (BSL) and I consider it one of New Zealand’s great shames that it has adopted such laws  (just one of the issues I raised when I submitted to the review of the Animal Welfare Act).

Breed specific legislation doesn’t work because, in part, these laws rely on visual identification of breeds.  If a dog is identified as one of the banned or dangerous breeds, it can (literally) be ‘all over, Rover.’

There’s scientific research that shows why visual identification is a fatal flaw in BSL.  Some of this research has been conducted by Dr Victoria Lea Voith who is based at the Western University of Health Sciences, College of Veterinary Medicine.

In 2009, Voith and her colleagues published results of a study comparing visual identification of dog breed with DNA results.   They showed that there was a very low accuracy rate when visual identifications were verified with DNA.  The research team concluded:

  • There is little correlation between dog adoption agencies’ identification of probable breed composition with the identification of breeds by DNA analysis
  • Further evaluation of the reliability and validity of visual dog breed identification is warranted
  • Justification of current public and private policies pertaining to breed specific regulations should be reviewed

This year (2013), Voith and her colleagues published another paper entitled “Comparison of Visual and DNA Breed Identification of Dogs and Inter-Observer Reliability”   Since their previous paper was based on the identification of breed by a single person, the research team wanted to see if the success rate of breed identification improved when multiple people were involved.  The research team presented one-minute video clips of the same 20 dogs to over 900 people who were engaged in dog-related professions or services.

For 14 of the dogs, fewer than 50% of the respondents visually identified breeds of dogs that matched DNA identification. For only 7 of the dogs was there agreement among more than 50% of the respondents regarding the most predominant breed of a mixed breed.  In 3 of those 7 cases, the visual identification did not match the DNA analysis.

This time, the research team concluded:

This study reveals large disparities between visual and DNA breed identification as well as differences among peoples’ visual identifications of dogs. These discrepancies raise questions concerning the accuracy of databases which supply demographic data on dog breeds for publications such as public health reports, articles on canine behavior, and the rationale for public and private restrictions pertaining to dog breeds.
