It’s impossible to predict a dog’s behaviour simply based on its appearance. The genes that determine a dog’s physical traits are not the same ones responsible for their behavioural traits.close
A zoologist from Stockholm University analyzed the behaviour of more than 13,000 dogs and concluded that pit bull type dogs were no more aggressive than other breeds. Another zoologist compiled data on the behaviour of more than 30,000 dogs from 300 different breeds over the course of 10 years. Conclusion: the most aggressive dogs toward humans are not pit bull type ones.close
The pit bull is not a breed, but a mix of several breeds, therefore making it difficult to identify a pit bull in order to implement BSL.
In Ontario, from 2005 to 2012 (when pit bull type dogs were prohibited), the number of hospitalizations due to severe dog bites actually rose by 45%!
Several countries have repealed BSL after noting how ineffective it was: the Netherlands, Spain, and the United Kingdom. In the United States, more than 20 states have prohibited municipalities from adopting BSL.close
