A couple of months ago, I noted that Delta, BC was looking at the possibility of repealing their breed-specific law.
Dropping the ban remains part of the discussion in Delta - and the idea appears to have a lot of support. But there is a bit more information that I want to share for those who have not spent a lot of time clicking through comment links here.
Back in April, Municple Solicitor Greg Vanstone wrote up a review of the community's current breed-specific law. But there are a couple of pieces of of his review that I want to highlight -- because he did a wealth of research on the topic of breed-specific laws, and I think his findings speak for themselves (all emphasis mine):
Staff researched this topic extensively but were unable to locate any studies that arrived at a list of dogs that are more genetically prone to fight or kill other animals or people. Instead, it appears that animal behaviour, characteristics and traits are determined by both genetics and environmental factors. Environmental factors that may affect a dog's behaviour include:
Other factors that may impact the aggressiveness of a dog include:
-
whether or not the dog is spayed or neutered
- pregnancy and whelping
- medical problems or injuries
As a result of this, dogs of the same breed can display a wide range of behavioural variability.
So after extensive research, they concluded that dog breeds can have a wide range of behaviors -- much of which is determined by its environment. Makes sense.
However, there's more. In a previous report -- which also included conversations with British Columbia's only Veterinary Behavior Specialist and the Canadian Vet Medical Association -- he concluded:
...staff are not aware of any studies that arrive at a list of dogs that are more genetically prone to fight or kill other animals or people. Instead, it appears that animal behaviour, characteristics and traits are determined by both genetics and environmental factors. One very influential element of environment is the wide range of human behaviour that dog may be exposed to. As a result, dogs of the same genotype (Breed) can display a wide range of behavioural variability.
This report goes on to give more detail over each of the individual environmental elements as well.
In the earlier report Vanstone notes:
To summarize, when determining if "Pit Bull" type dogs should remain in the bylaw as "Dangerous" or "Aggressive", genetics are only part of the equation. Evaluating society's influence on breeds should also be considered. Human involvement in breeding and influencing environmental factors have to be considered when determining if one type of dog is going to be more aggressive than another.
Most people shouldn't be surprised by Vanstone's findings. You can't judge dogs without judging people -- because people are one of the single biggest determinents of how dogs turn out. Focusing only on the dogs (by focusing on breed) misses the largest part of the equation.
And this is why Breed Specific Laws fail.
Vanstone's report is not at all a surprise to me (or to most I'm sure). When unbiased research is done, and when experts are consulted, the evidence becomes clear -- laws should be focused on owners, not breeds of dogs. It is only when decisions are made in the hysteria of the moment, or under the hope of political gain, that breed-based laws come into play.
Good luck to the city of Delta as they work to possibly remove breed-specific laws from their books based on sound research and expert opinion.
