The latest research on breed specific legislation formalises a lot of the information that I already suspected or knew from other sources:  that BSL doesn’t work and is a flawed concept.    Read more below:

Research conducted by animal behaviour experts challenges the basis of breed specific legislation designed to protect the public from ‘dangerous’ dogs.

A team from the University of Lincoln, UK, concluded that rather than making people safer, current legislation could be lulling them into a false sense of security. Their findings were recently published in the journal Human Animal Interaction Bulletin published by the American Psychological Association, in a freely available paper “Acculturation – Perceptions of breed differences in behavior of the dog (Canis familiaris)”.

Dr Tracey Clarke and Professors Daniel Mills and Jonathan Cooper from Lincoln’s School of Life Sciences set out to discover the source of people’s perceptions about ‘typical behaviours’ associated with different breeds of dog.

Professor Mills said: “This work provides good scientific evidence to explain why the pursuit by governments of breed specific legislation to reduce the risk of harm to citizens is not only doomed to failure, but also giving people a false sense of security, which may actually be making the situation worse.”

The researchers applied a theory known as the ‘contact hypothesis’ – used by sociologists to understand the origin of racial stereotyping and other forms of prejudice.

They surveyed more than 160 people to examine if their contact with dogs influenced their tendency to believe populist and negative breed stereotypes.

They found significant variations in attitudes between people who owned dogs or had regular contact with them, and those who did not. More than half (54%) of respondents who identified themselves as “experienced or knowledgeable” of dogs disagreed with the statement that some breeds are more aggressive than others. Only 15% of respondents who said they had little or no experience of dogs held the same view.

Similarly, more than half of the “experienced” respondents felt there was no valid reason for breed specific legislation, whereas less than 1 in 10 of the inexperienced respondents felt the same.

The results were consistent with the prediction that not just the level but also the quality of contact with dogs are major influences on the tendency to believe populist breed stereotypes, despite scientific evidence which challenges the validity of such generalisations.

The variability within a breed is nearly always greater than the variability between breeds for behavioural traits, meaning while there may be differences on average, when it comes to assessing the likelihood that a particular individual will behave in a certain way generalisations are often unsound. The type of person attracted towards certain breeds and encouraging certain behaviours may be a much better predictor.

It was discovered that a dog’s visible characteristics informed strong attitudes, resulting in over-generalisation. Not only bull-breeds but also those with much more superficial characteristics such as being well-muscled, or even short-haired, were stigmatised more often as dangerous by those with less experience or knowledge of dogs.

Attraction to certain types on the basis of their appearance, can then lead to these being preferred for use as a weapon or status dog, creating a self-fulfilling prophecy about their behaviour through environmental rather than genetic effects.

The team suggest that further scientific research is needed to improve understanding of the origins and basis of negative breed stereotypes, and that this in turn should be used to inform future legislation.

The White House’s official position on breed specific legislation

Whoopee!  (or should I say ‘woof woof’).  This week the White House put out an official statement concerning its position on breed specific legislation.   And it’s great news…

“We don’t support breed-specific legislation — research shows that bans on certain types of dogs are largely ineffective and often a waste of public resources.

In 2000, the Centers for Disease Control and Prevention looked at twenty years of data about dog bites and human fatalities in the United States. They found that fatal attacks represent a very small proportion of dog bite injuries to people and that it’s virtually impossible to calculate bite rates for specific breeds.

The CDC also noted that the types of people who look to exploit dogs aren’t deterred by breed regulations — when their communities establish a ban, these people just seek out new, unregulated breeds. And the simple fact is that dogs of any breed can become dangerous when they’re intentionally or unintentionally raised to be aggressive.

For all those reasons, the CDC officially recommends against breed-specific legislation — which they call inappropriate. You can read more from them here.

As an alternative to breed-specific policies, the CDC recommends a community-based approach to prevent dog bites. And ultimately, we think that’s a much more promising way to build stronger communities of pets and pet owners.”

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.
