This was an interesting news report from a couple of weeks ago out of Calgary.
In a citywide poll, seniors in Calgary were more likely to be in favor of outlawing 'pit bulls and other large canines' more so than younger Calgarians, who overwhelmingly rejected such a law.
According to the poll, 64% of those over the age of 70 supported breed bans, while only 19% of those aged 18-29 were in favor. Overall, 48% opposed breed bans, while 40% supported them.
It's worth noting that the poll was done as a non-random internet poll, so the data is far from scientific, but it does reflect similar research done over the years that indicates that while older people tend to favor breed specific laws (likely rooted in decades old hysteria that no longer has merit), younger people overwhelmingly oppose BSL. This also helps us understand why more and more communities are continuing to move away from the idea of breed-specific legislation and instead, moving more toward breed-neutral policies that focus on the behavior of the dogs.
It's also worth noting that Calgary, with its breed-neutral, behavior-based policies, has long been upheld as one of the models of animal control in North America (even though a very recent trend line, in part due to how bites are reported, has caused an increase in bite reports in the past cocuple of years).
