What is Breed-Specific Legislation (BSL)?
Breed-specific legislation refers to laws that regulate or ban certain dog breeds based on the assumption that certain breeds are more dangerous or prone to aggression. These laws are enacted by various governments, municipalities, and regions to address concerns about dog attacks, injuries, and public safety.
However, BSL is controversial. Opponents argue that it unfairly targets specific breeds rather than addressing individual dog behavior, training, and owner responsibility. Supporters of BSL argue that banning specific breeds reduces the risk of attacks by focusing on breeds with certain physical characteristics, such as strength and bite capacity.
